Oxy-Fuel & Inert Gas Quick Connect Couplers – Heavy-Duty Brass, UL Listed, CGA Compliant

Improve safety, efficiency, and convenience in your welding setup with these professional-grade Oxy-Fuel and Inert Gas Quick Connect Couplers. Designed for reliability in demanding welding and cutting environments, these quick-connect fittings allow operators to rapidly connect and disconnect gas lines while maintaining a secure, gas-tight seal. Built from durable brass and engineered for long service life, they are ideal for use with B-Size welding and cutting equipment in fabrication shops, repair facilities, and industrial settings.

Colour-Coded Gas Identification for Safety

Each model is colour-coded for gas service to prevent mistakes and enhance workplace safety:

• Green – Oxygen

• Red – Fuel Gas

• Blue – Inert Gas

The non-interchangeable oxygen and fuel gas connectors further prevent accidental gas mixing, protecting both equipment and operators.

Integrated Safety Check Valves

Oxy/fuel models include integral reverse-flow check valves that provide instant shutoff at just 10 oz. of back pressure, preventing dangerous reverse gas flow. This rapid response helps protect regulators, hoses, and torches from contamination or flashback hazards.

High Flow Performance

These quick-connect couplers are engineered to exceed CGA flow specifications, delivering excellent gas throughput for demanding welding and cutting operations:

• 1100 SCFH flow at 125 PSIG inlet pressure

• 800 SCFH flow at 125 PSIG inlet pressure when used with two additional check valves

Durable Brass Construction

Manufactured from high-quality brass, these connectors are cycle-tested for over 10,000 operations, providing an estimated service life of 10–12 years under normal use. Their rugged construction makes them suitable for professional workshops and industrial environments.

Secure, Gas-Tight Connections

A spring-loaded locking mechanism allows for smooth fingertip operation and ensures a secure, gas-tight connection every time. The double-seal socket design adds an additional layer of safety by providing a secondary seal during connection.

Specialized Inert Gas Safety

In inert gas models, a demand valve on the supply side automatically creates a positive seal whenever the fitting is disconnected. This prevents gas leakage and maintains system integrity.
