  • Model 004620 and 004885
  • 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.
  • Model 004620 is not for use in California / EVR applications.
  • Model 004620 is a slip-on vent cap with a main pliable seal that seals to the vent stack and provides leak proof protection because the seal is at the end of the vent stack, not on the threads.
  • Model 004620 uses four (4) stainless steel set screws to grip the vent stack preventing any loosening of the seal.
  • Constructed from materials 100% compatible with B0-B20 and E0-E85.
