  • The Husky® 5885* pressure / vacuum (P/V) vent incorporates three separate valves to control over-pressure and vacuum conditions that arise in storage tanks. This three valve system provides the necessary protection and durability needed in a UST vent cap.
  • The 5885 has an internal screen to protect the pressure plate in the event of a bad bulk drop.
  • The vacuum valve is diaphragm operated and provides 10 times more sealing force than gravity devices. It consistantly opens at 6” – 10” of water column (WC) / 1.5 – 2.5 KPa vacuum.
  • The first over-pressure valve is diaphragm operated, giving 10 times more sealing force than gravity devices. It opens at 2.5” – 6” WC / .63 – 1.5 KPa pressure.
  • The safety over-pressure valve is designed to handle high pressure / high flow conditions. This valve will vent up to 7900 SCFH at 2 psi / .14 bar.
  • 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.
  • The 5885 is a threaded vent cap that is easily installed by using the cast-on hex nut. This also allows tightening without having to go between vent pipes.
  • Constructed from materials 100% compatible with B0-B20 and E0-E85.
