Threaded Vapor Recovery Adapter

Use this Vapor Check Valve to return vapor to the truck during terminal loading and service station drops. The 3 in. poppet opens when coupled and closes when disconnected, preventing the vapors from escaping into the atmosphere. The valve has 3 in. or 4 in. female NPSM threads, a 4 in. cam and groove, and tapped mounting holes for the EBW Air Interlock Brake. The 303 series is available without a poppet to serve as a male quick coupler with an Air Interlock Valve mounting pad.

  • Anodized aluminum construction.
  • Stainless steel stem and spring.
