high pressure fuel line fittings

by Teresa Bechtelar IV Published 4 years ago Updated 3 years ago

The high-pressure tubing and fittings are critical components of NGVs because they carry fuel throughout the entire CNG high-pressure fuel system. CNG vehicles use reliable high-pressure stainless steel, seamless fuel tubes, as well as fittings which are typically double-ferrule compression or O-ring face seal type.
