From Airtime:

We developed the Valve Trap because people have asked us for years why they couldn’t re-use their perfectly good valves when they started leaking. This is the solution that lets you quickly and permanently attach a new or used valve to any bladder.

Repair old bladders or assemble new. The Valve Trap sandwiches any valve between two layers of soft foam and seals the valve in place with a specialized adhesive. The Valve Trap then provides a large 4″ diameter base with ‘peel and stick’ adhesive that will permanently adhere to any bladder, new or used. Don’t quite understand how it works?

Perfect fix to re-attach original valves when they come loose and begin to leak. Keep your original valve and be back on the water in minutes.

ATTENTION: – Do not use the Valve Trap with a ball valve. Replace faulty ball valves with new one-way valves (check-flap style). – Make sure the valve spacing is correct when using the valve trap. If the valve spacing is off or if the bladder is not seated correctly and there is “pull” on the valve it can cause premature failure. – Check all valves for cracks and/or wear before re-sticking them with the Valve Trap.
