Care of the Vac Rac

Safety Caution:



Latex is air tight, acquire the knowledge needed to avoid risks of injury or suffocation. When in use ensure that the airway cannot become blocked or obstructed at any time under any situation. Check with your physician if you need information regarding allergies to silicone or latex products.

Parts Making Up The Vac Rac

There are 6 pieces of 2" perforated plastic pipe forms the frame placed inside the vac rac latex bag

The latex bag with one way valve.

Optional: latex hood, connectors and short hose can be used as an airway

Optional: Storage bag recommended

Optional: Vacuum


Use a space that is large enough to walk around the vac rac and a flat continuous surface. Beds are not adequate

Lay out the latex bag on the firm continuous surface. Do not try to use a bed, damage to the vac rac bag will result. Use a floor or large firm padded surface that supports the entire vac rac bag.

Take a pvc end tube (no elbows) and insert the side tube with the sliding connector, the hex head bolt for the slider facing up. Install the two pieces into the foot of the vac rac. The end tube is placed at the foot of the vac rac taking care not to catch or stretch the latex sheet, as well, be careful not to pinch the latex sheeting in the elbow. The side tube will be next to the side furthest from the zipper of the bag.

Should pipes come apart in installation we suggest reaching through the latex to guide the pipes into the proper location and connection.

Similarly take the top tube with no elbows insert a pvc side pipe (no connector) into the top tube furthest from the zipper. Slide the two pieces into the bag with the top tube at the head of the bag. Reaching into the bag or carefully handling through the latex sheet bring the two side pieces together in the centre of the bag and join at the connector. Slide the internal slider tube across to hold the two pipes together.

Insert to the zipper side, the pipe with the slider connector into the foot tube.

The remaining side tube without the connector is best not installed at this point.

Getting In The Vac rac

Note: the users including attendants, should not be wearing any jewelry or metal items that may tear the latex. Sharp finger and toe nails need to be trimmed or covered. It is recommended that socks be used on feet and if necessary hands to prevent nails from tearing or snagging the latex. Using boots or heavy helmets, gas masks, leather gear can cause damage to the sheeting.

The User should sit beside to the midpoint of the open zipper. Put feet into the zipper opening. Now is a good time to install the hood if any is used.

Slide carefully into the bag feet first. With the head in the bag use hands to keep the top latex sheet from blocking the User's airway. Assist the User into position aligning the mouthpiece or breathing tubes so they are directly beneath the breathing hole in the upper latex sheet. Pull the vac rac sheet over the mouthpiece or hose and align for comfort as well as to ensure there is no stretching or stress on the breathing hole.

Insert the zipper side pipe into the top tube.  Slide the connector across the joint between upper and lower side tube.

Check to make sure the elbows, and inner side connections have not loosened or come apart. Fix if necessary at this point by reaching through the latex sheet, be careful to ensure you do not pinch the latex in the joints.

Check carefully that the latex bag is not curled, or, twisted or caught in the pipes.

Confirm with the occupant the use of safety signals, and the airway is clear of obstructions.

Care and Closing the Gasproof Zipper

The zipper is the most expensive component of the vac rac parts. It is a gas proof zipper intended for use in dry suits and hazmat protection gear. Care of the zipper is paramount at all times.

Before operating the zipper ensure that the zipper teeth have been lubricated with the special wax stick or tube designed just for that purpose. The lube stick should be glided over the outer and inner zipper teeth.The drysuit zipper lubricant is available at camping and scuba diving stores. We can also supply the lube. Lubricate the zipper after each wash and dry and if any stiffness is detected in opening or closing the zipper apply lube immediately.

Place one hand on the end of the zipper tape, use the other to gently pull on the zipper slider to close the zipper. Be careful that no latex material gets caught in the zipper, especially when opening the zipper. OPening and closing the zipper is best accomplished only when the piping is installed and rigid. The Zipper can glide more easily against the firm surface. It is not recommended to open or close the zipper any more than is necessary. A rule of thumb is: Each opening or closing of a zipper costs $5.00 in terms of wear. However we have zippers that are 20 years old and still in good condition.

Close the zipper leaving with about 6" remaining from the end.

The outlet valve

Using a vacuum source, hold the suction hose a few inches from the one way valve prtrding from the top of the vac rac sheet.

The vacuum directly on the valve may be too strong and cause damage to the valve as well as suck air out too quickly. The strong suction, may leave the occupant fearful. Take your time.

See the photos on our web page.

Check the occupant comfort. We suggest several minutes be provided for the occupant to acclimatize to the sensations. When suitable, close the zipper completely. The bag is airtight unless the occupant exhales into the bag. Hoods or similar devices can limit this air leak.

Slowly suck out air, a little at a time, monitor the occupant comfort. Once the vacuum intensity desired has been reached, you can shut off the vacuum source.

Variations in Use

Once the vacuum is achieved, the User can relax and enjoy the tight latex sensation surrounding them. The ability to move in the bag is limited if not impossible. restraints are really not necessary.

Some people will want some interaction with their partner. Such play should ensure that the late sheet cannot be overstretched, snagged or torn by any type of sharp object especially finger nails and jewelry.

Tactile sensations are heightened by the latex layer. Suggestions include massage with ice, or warm items rubbed across the latex sheet. This may add stimulation to the User. Vibrators can be used as well. Gentle to firm touch can evoke strong sensual sensations .Electrical gear, or clamps of any kind with sharp connectors must be avoided. Ensure that the surface of the vacbed is lubricated with a water based lube or silicone glide so that objects cannot abrade, scratch or tear the surface

Using the latex bag without the pvc frame.

Another way to use the latex vacuum bed is to leave off the pvc pipe. Have the User get in the bag, establish a safe airway and then remove the air. While there is more mobility it offers a different vacuum experience.

About the use of the Optional hood

Vac Rac Hood with mouthpiece

An extra large hood, black colour, mouth opening only.

Supply of tubes and other accessories may be inserted into the scuba mouthpiece

Mouthpiece fits into opening in the hood. If silicone or other lubricants are used, the mouthpiece may be difficult to retain in the hood or vac rac bag.

The mouth piece is then pulled through the opening in the Vac rac bag airway opening. As air is removed the hood will fit tightly over the head, air exchange is only through the breathing tubes or mouthpiece. The risk of the mouthpiece separating from the hood or vac rac bag is possible, be aware of this possibility when moving the head or making sudden movements.

Danger - This is a High Risk Experience

Please read carefully

At no time should the occupant be left unobserved by one or more attendants. Always have the attendants stationed at the side of the vac rac bag to open the zipper instantly if a situation occurs.

There are many risks associated with restriction from suction, vacuum and airway obstruction. Caught-In-The-Act recommends that the participants be trained by knowledgeable and experienced vac rac users. Sources on the Internet, training seminars, books and other resources may help inform the users. Caught-in-The-Act offer their products as novelties only. Please review your risks and responsibilities in the use of any product that may be used in a situation where the partial or complete loss of control by a user may occur. Under no circumstance should the vac rac be used without attendants present (solo experiences).

Cleaning Suggestions

During play with multiple users

Have paper towel, rubber gloves, alcohol available for sanitary use of the vac.

Where it is not practical to clean the vac rac between Users we suggest that isopropyl alcohol (70%) be used to wipe down the surfaces of the vac pac that have come in contact with the User's skin.Any body fluids should be mopped up before cleaning with alcohol. The alcohol will dry in a few minutes. Be sure to clean the hood and mouthpiece with alcohol between Users.


The vac rac bag must be cleaned after use. Leave the zipper open fully, turn inside out and place in a bathtub of cool or warm water with dish soap (unscented and no oil additives) Wash with a soft cloth wiping all areas of the latex surface inside and out. Drain the tub and then rinse thoroughly with cool or cold water. We use a flexible shower head for that. Drain the excess water.


By far the most difficult care aspect of the vac rac. Drape over a railing or similar surface that allows both sides to dry at once. Ensure that there are no sharp objects or points to tear the latex or kink the zipper. We recommend a fan blow across the vac rac to aid in the drying. Once the exposed side top and bottom are dry, powder lightly and turn out the bag so the exterior can be dried. Once dry powder both inside and out or (silicone can be applied to the outside only). It will take a minimum of 24 hours for the bag to dry, in humid weather even longer. Latex does hold moisture, even if the bag feels dry after a few minutes it will take at least 24 hours to dry the latex fully.

The Best Way To Dry The Vac rac

After washing lay out the wet vac rac inside out on a flat surface covered with towels or a sheet to absorb the water. Lubricate the zipper and carefully close the zipper part way leaving 10 - 12" from the end. Using a hair dryer rig up the dryer with the end of the dryer in the opening of the zipper. Set the dryer to cool or cold and high speed. With the dryer on the bag will inflate, adjust the inflation so that there is good air flow inside. This inflation keeps the surfaces apart and aids in quickly drying the bag. Latex will stick to itself, therefore the dryer helps to keeps the latex from sticking until dry and powdered. While the bag is inflated wipe off excess moisture form the exterior. When  the outer surface is dry reverse the bag  turning out and dry in a similar manner. You may need to replace the wet sheets or towels with dry ones. Powder or silicone but hang to air dry a minimum of 24 hours before storing. We dry ours for 48 hours after powder and silicone is used to protect the surfaces.


Store in a cool dark place ensuring that the zipper is not compressed or kinked. Apply a small tube to any part of the folded zipper, and always store with the zipper lubricated and in the open position. An inert plastic bag will help prevent the bag from oxidizing. Be careful in using garbage bags that may contain oils and anti-bacterial residues that can easily damage the vac rac. If in double don't use.

We recommend the use of the optional cotton storage bag that holds, the pipes, bag , hood and vacuum.

Summary on Care

Latex sheets can catch on sharp objects and rip, be especially cautious when washing and drying the bag. Protect the latex from sharp finger nails and toe nails. Do not use with any metal devices or jewelry that may come in contact with the surface. If you use a silicone shine as protectorant extra care is needed as the sheets will tend to stick to the occupant. excessive stress can cause a tear. We highly recommend using powder on the bag surfaces inside and out. Wash and dry thoroughly as per the latex FAQ links. The airtight dry suit type zipper does require frequent lubrication. If it is hard to open or close, use dry suit zipper lubricant available at sports stores and dive shops. Do not kink, bend sharply or pull on the zipper components, which could result in damage to the zipper. Store the zipper in the open position to prevent premature wear and leaks. Make sure the latex is washed after use, dry well allow at least 24 hours to dry, then powder and store loosely in a storage bag. Always store in a cool dark location.


About Amber Latex

Why is it not absolutely clear?

Latex is a natural gum rubber taken from trees. The rubber is a translucent white material that when cured and made into latex sheets has a translucent not transparent look. The thicker the latex sheet the darker and less translucent it is. When the latex is wet, it has the wet look, it is more transparent .

Will the colour remain the same or does it get darker?

All natural gum rubber will darken to a deep amber/brown colour with age. The change will be faster if the latex is exposed to sunlight, harsh chemicals or certain metals. Thinner material because it is less dense will stay lighter in tone longer than thick material.

What happens if it comes in contact with metal?

Some metals will turn amber very dark brown on contact. In particular, any copper, brass and composites with darken the material quickly. If left in contact with brass or copper composites the latex will deteriorate rapidly.

Can stains be cleaned off the amber latex?

Not likely. Amber has a drawback and that is the ability to absorb colours. Ink can be wiped off with alcohol, and some stains may wipe off with rubber cement thinner, however, most dyes will not wash out of the latex.

How can I treat it to limit discolouration?

Wash and dry as for any latex but keep the bag out of the way of metals, strong scented soaps, and metallic powders. Store in a clean dry plastic or plain cloth (no dye) storage bag. When in use try to ensure the surfaces used are clean and from from oils, and dirt. If a painted surface make sure the paint is not oil base. Amber does darken and stain easily but the material should remain durable and strong for several years.

Safety Issue on the use of Talc

Very Important Warning - Please Read

Talc and similar powders should not be used except under very careful circumstances. Airborne particles of talc will accumulate in the lungs causing the potential for diseases. If any powder is needed ensure that a respirator is used or similar to limit the inhalation of the dust.

The same concern applies to sprays such as silicone protectorant shine for latex. Once again we caution to use a mask to protect from the particles entering the airways.

Powders that dissolve in water and are also proven to be non-toxic are preferred dusting agents to keep latex from sticking.

Seek out the advice of your physician on medical maters with respect to latex products and protectorants.
