Vapour Coupler - VCF500

Vapour couplers allow for vapour transfer between tanker trucks and loading/unloading tanks.

Liquip's vapour couplers automatically open when connected to a compatible vapour adaptor and automatically seal when disconnected.

Liquip offers a 100mm (4") with poppet and spigot that can be used for vapour transfer between the tank truck and loading/unloading tank. 

The VCF500 is a spring loaded coupler that automatically opens when coupled to a compatible adaptor.

Features & Benefits

  • Unique hinged poppet design provides lower pressure drops than standard poppets at high flows rates.
  • Spring loaded poppet retains vapours until coupled to the male vapour adaptor.
  • Universal 4" (100mm) camlock connection.
  • Automatically seals when disconnected for increased operator safety.
  • Patented “dunny lid” poppet to minimum pressure drop across the valve.
