OPW has developed an in-line breakaway that can be used in heavy-duty truck and bus NGV refueling applications. This unit will function consistently, independent of the inlet pressure.


  • Body: - stainless steel
  • Internal Parts: - stainless steel
  • Seals: - specialty formulated polymers and elastomers specific to high pressure NGV applications
