US Hose Corp. 1/2" CNG Hose

What pressure, flow and temperature is it rated for?

This hose is rated for 5000 PSIG maximum allowable working pressure. The listing does not specify flow capacity or temperature range; you'll need to ask the seller for those operating limits and verify them against the manufacturer's data plate or documentation.

What gases is it compatible with, and has it been oxygen cleaned?

This hose is built to NFPA 52 for compressed natural gas (CNG) service. The listing does not indicate oxygen cleaning or compatibility with other gases; CNG hoses typically use elastomers and constructions that are not suitable for oxygen service without specific cleaning and material selection.

What should I inspect before putting it into service?

Examine the entire hose length for kinking, abrasion, cuts, or cover damage that could compromise the reinforcement. Check both end fittings for cracks, corrosion, and thread condition, and verify the hose has not exceeded its service life per NFPA 52 requirements. Pressure test to rated MAWP and inspect for leaks at fittings; also verify the legibility of any date stamps or certifications required for compliance.
