#004885: Pressure/Vacuum Vents
Standard P/V Vents
2 in / 51 mm Thread-On Pressure / Vacuum Vent Cap
Product Info
Other Information
All Pressure/Vacuum Vents have three (3) separate valves that address pressure/vacuum conditions in underground storage tanks (UST) and above ground storage tanks (AST).
  • The three (3) valve system provides the necessary protection and durability needed in UST and AST vent caps.
  • The vacuum valve is diaphragm operated and provides ten (10) times more sealing force than gravity devices. It consistently opens at 6” - 10” of water column (WC) / 1.5 - 2.5 KPa vacuum.
  • The first over-pressure valve is diaphragm operated, giving ten (10) times more sealing force than gravity devices. It opens at 2.5” - 6” WC / .63 - 1.5 KPa pressure.
  • Not for use in California / EVR applications.
  • Certified to less than 1/3 of the CARB EVR Standard CP-201 which allows installation of three (3) P/V Vents maximum. This reduces installation time by not having to manifold the vent pipes together.
  • Threaded vent cap that is easily installed by using the caston hex nut which allows tightening without having to go between vent pipes.
  • Constructed from materials 100% compatible with B0-B20 and E0-E85.
