Hose offering naming CNG high-pressure and vent-line service.
The supplier names CNG high-pressure hoses and vent hoses within one catalog offering. The duty should be selected explicitly because a transfer hose and a vent connection need not share the same assembly specification. Provide the required service and end fittings, then confirm the hose construction, length and documented operating limits for the quoted assembly.
