CGA-510 Acetylene Regulator Inlet Nut, Brass, Left Hand Male

Reliable Replacement Inlet Nut for Acetylene Regulators

Keep your oxy-fuel equipment running safely and efficiently with the Western Enterprises 15-2 Inlet Nut. Designed for professional welders and fabricators, this replacement nut is essential for connecting your regulator to CGA-510 acetylene cylinders (often referred to as POL connections). Over time, the threads on regulator nuts can become worn, stripped, or damaged from frequent cylinder changes. A compromised nut can lead to dangerous gas leaks or poor flow; replacing it with a high-quality brass fitting ensures a tight, secure seal every time you swap tanks.

Safety is paramount in welding, and this nut incorporates the industry-standard Left-Hand (LH) thread to distinguish it from non-fuel gas fittings. The .880"-14 NGO thread pitch is precision-machined to prevent cross-threading and ensure a smooth connection to the cylinder valve. Constructed from solid brass, it withstands the wear and tear of daily shop use and resists deformation under torque. The brass material also minimizes the risk of sparking during connection, an important consideration when working with fuel gases.

The 1-1/8" hex body provides ample grip for your wrench, making cylinder changes quick and easy even when wearing gloves. Rated for up to 500 PSIG, this nut handles the pressure requirements of standard acetylene service without issue. Whether you are outfitting a cutting torch rig, setting up a heating station, or maintaining a shop manifold, trust Western Enterprises fittings for their consistent quality and adherence to safety standards. Always ensure your regulator nipple is in good condition when replacing the nut to guarantee a proper seat.
