Studor Mini-Vent Air Admittance Valve with ABS Adapter is a one way valve used for branch or single fixture ventilation. It protects the water trap seals and does not allow sewer gases and smells to leak into the living space. When a negative pressure in the drainage pipe occurs, the valve opens to allow the entrance of air. When the pressure is balanced the Mini-Vent closes absolutely tight, so the foul air cannot escape. Fits: 1-1/2 or 2-inch x 2.625-inch vent height x 2-inch vent diameter. ABS construction with a temperature rating of -40 to 150 deg F.

It also comes with an adapter for a 2" pipe. **Q: what is life span for mini vent** A: We just replaced two, both had replaced vents that were about 8 years old. **Q: Are these suitable for exterior vent pipes?** A: My understanding is they are only for use inside.
