WES72 - CGA-555 Brass Nut .908-14 NGO LH Female for Liquid Propane/Butane

Reliable Liquid Withdrawal Connections for Pros

When your welding or industrial application demands liquid propane or butane, safety and reliability are non-negotiable. The Western Enterprises WES72 CGA-555 Nut is the industry-standard solution for connecting to liquid withdrawal cylinders. Whether you are running high-output heating systems, specialized cutting equipment, or laboratory apparatus, this nut ensures that your gas supply lines are connected securely and correctly every time. Made in the USA, this part represents the durability and precision that professional welders and tradespeople expect from Western Enterprises.

One of the standout features of the WES72 is its specific design for liquid withdrawal. Liquid propane and butane behave differently than their vapor counterparts, and using the wrong connection can lead to equipment damage or dangerous safety hazards. This nut utilizes a Left-Hand (LH) thread pattern (.908"-14 NGO), which means it tightens to the left. This distinct threading acts as a safety key, making it impossible to accidentally attach a vapor regulator or hose to a liquid cylinder. This simple but effective design feature protects your equipment and your crew from potential mishaps on the shop floor.

Constructed from solid brass, the WES72 is built to last. Brass is the material of choice for gas fittings due to its spark resistance and durability. It resists galling, ensuring that the threads remain clean and smooth even after repeated cylinder changes. The 1-1/8" hex design provides ample surface area for your wrench, allowing you to apply the necessary torque for a leak-proof seal without rounding off the edges. Rated for pressures up to 3000 PSIG, this nut handles the requirements of full cylinders with ease.

Installation is straightforward. Simply pair this nut with the appropriate CGA-555 nipple (tailpiece) for your hose or regulator stem. Ensure your cylinder valve is clean, align the threads, and tighten counter-clockwise. Whether you are setting up a new manifold or replacing worn-out fittings on your existing rig, the WES72 provides the peace of mind that comes with using high-quality, compliant hardware. Don't compromise on your gas connections; choose the fitting designed specifically for the job.
