Simple Air Admittance Valve Kit for 1-1/2 inch Tubing with 2x Superior Seal

The TUUBER Air Admittance Valve is the only patented dual sealing air admittance valve that offers 2x the superior seal to prevent sewer gas and odors from escaping into a home or building. The valve is designed to open and satisfy negative pressures that can develop in the plumbing drain system when a fixture begins to drain, allowing air to enter the drain system. The valve's two seals then close by gravity at zero (0) differential pressure, and under positive internal pressure and in low-pressure conditions.

The TUUBER Air Admittance Valve can be used in new or existing applications as a secondary vent alternative to a vent extended to the roof outside. It features 1-1/2" NPT threads, and approved thread sealant must be used on the threads of the valve. Installers should read all installation instructions prior to use.

The valve's key features include:

• Fits 1-1/2-inch Piping
• Two Seals (2x the superior sealing capability)
• Triple Flow Passage ultra sensitive to pressure changes
• Automatically opens on system vacuum pressure to allow air in
• Closes by Gravity with Dual Seal Protection Capability

The purpose of an air admittance valve is to provide a method of allowing air to enter a plumbing system as an alternative to a vent extended outside, to prevent plumbing system sewer gases from entering a building, and to protect against siphonage of a plumbing fixture trap. The TUUBER valve uses a patented dual seal utility and a patented triple flow passage utility that is sensitive to pressure changes, allowing the upper and lower seals to lock out sewage gases and odors.

The TUUBER Air Admittance Valve offers a Lifetime of Reliability, with its patented dual sealing and triple flow passage design. It automatically opens to satisfy negative pressures, and closes by gravity and under positive internal pressure. The valve can be used with the TUUBER 1-1/2-inch Air Admittance Valve & Trap Kit, which includes a Tubular Tee Pre-Assembled Trap and additional parts for multiple configuration options, connecting to threaded or slip joint pipe ends.
