QUICK COUPLING GAS FITTING — durable coupling and fitting sets for hoses and pipework
A quick coupling gas fitting from REAL GAZ combines a coupling body with the correct thread, hose tail or compression end, so the unit can be fitted straight into hose assemblies and distribution pipework. It suits users who want a complete, ready-to-install joint.
Our range includes male and female ends in common metric and inch threads, with right-hand and left-hand forms for fuel gases.

Couplings follow ISO 7289 design principles, with hose connections consistent with EN 560 and hoses to EN ISO 3821, for industrial, trade and maintenance users.
Typical sets use hose bores of 6.3, 8 and 10 mm, brass bodies with nickel plating, and nitrile or EPDM seals. Larger industrial sets with 3/8 inch and 1/2 inch threads are available for heating burners and bulk supply lines.
