Western Enterprises 73 CGA-555 Brass Nipple, 1/4" NPT Male, 2-1/16" Length

Reliable Connections for Industrial Propane

For welders and fabricators utilizing liquid propane for specialized heating, cutting, or engine fuel applications, the Western Enterprises 73 Nipple is an essential fitting. This brass nipple is specifically engineered to adapt CGA 555 cylinder valves—designated for liquid withdrawal—to standard 1/4" NPT piping systems. When your project demands a consistent liquid fuel supply, ensuring you have the correct adapter is the first step toward a safe and efficient workflow.

Constructed from solid brass, this fitting is built to withstand the rigors of the shop and the field. The 2-1/16" length provides ample clearance for wrenching and ensures compatibility with standard CGA 555 nuts. The 1/4" NPT Male thread allows for easy integration into existing hoses, regulators, or hard piping, making it a versatile problem-solver for custom gas setups. Western Enterprises has a long-standing reputation in the welding industry for producing fittings that don't strip, crack, or leak under normal use.

One of the primary advantages of using the Western Enterprises 73 is the prevention of cross-contamination between liquid and vapor lines. Since CGA 555 is distinct from the vapor withdrawal CGA 510 connection, using this nipple helps enforce safety by mechanically preventing the wrong type of regulator or hose from being attached. This is crucial in busy workshops where cylinders may be swapped frequently.

Whether you are repairing a forklift fuel line, setting up a high-output burner, or maintaining a manifold system, this nipple offers the peace of mind that comes with using professional-grade hardware. It is compatible with standard liquid propane and butane cylinders and is designed to provide a gas-tight seal that you can trust. Upgrade your gas equipment connections with Western Enterprises fittings for superior performance and safety.
