Western Enterprises CGA Fittings

Regulator Inlet Nuts & Nipples

Western offers nuts and nipples in a variety of materials and styles to fit a full range of gas service requirements. Five different types of nut/nipple combinations are available:

Brass nut and nipple.
Stainless steel nut and nipple.
Nut and nipple with check valve.
Nut and nipple recessed for tubing.
Hand tight nut and nipple.

Please note that all types may not be available for certain gas services.

Nipples with check valves:
Nipples with integral check valves are designed to provide additional safety in Manifold Systems and other equipment.

Check valves nipples can be built into pigtails, tee connections and manifold blocks to resist back flow of gases from lines, equipment and cylinders.
Check valves are factory installed and 100% tested.
Check valves are for reverse flows only - they care not to be used as Flashback Arrestors.

Hand tight nuts and nipples:
Western Hand-Tight Nuts provide for easy installation and are available in brass or with plastic grips.

Lightweight plastic grips have labels which are colour-coded for gas service.
All brass nuts are machined to CGA specifications and designed with wrench flats.
Soft tip or O-ring type nipples always should be used with handtight nuts.
CGA fittings rated over 3000 psig do not have soft tips and final gas-tight seating requires wrench action.
