Adaptor Bushing CGA-580 X3/4 " Mnpt

Durable Cylinder Connection for Professional Welding Setups

For professional welders and fabricators, reliable gas flow is the backbone of a quality weld. The Western Enterprises B-73 (SKU: WESB-73) is a heavy-duty brass adaptor bushing that solves the common problem of connecting standard shielding gas cylinders to larger manifold systems or specialized equipment. If you are running a shop with centralized gas distribution or using heavy-duty regulators that require a 3/4" NPT input, this is the fitting you need to bridge the gap from your tank.

This adaptor is designed to fit the standard CGA-580 valve found on Argon, Nitrogen, and Helium tanks—the bread and butter gases for TIG and MIG welding processes. The female end screws directly onto your cylinder valve with a .965"-14 NGO thread, while the male end offers a rugged 3/4" NPT connection. This setup is particularly useful for shop manifolds where multiple cylinders are banked together to provide a continuous gas supply for multiple welding stations. The solid brass construction ensures that the threads won't strip easily and that the fitting can withstand the daily rigors of a busy fabrication shop, including the accidental bumps and knocks that happen when changing out heavy cylinders.

Rated for 3000 PSIG, the B-73 can handle the full pressure of a fresh cylinder with ease. The large 1-1/8" hex shape gives you plenty of surface area to get a wrench on it, ensuring you can tighten it down sufficiently to prevent costly gas leaks. Leaks not only waste expensive shielding gas but can also introduce atmospheric contamination into your weld pool, leading to porosity and defects. Using a high-quality adaptor like the Western Enterprises B-73 minimizes these risks by providing a precision-machined seal you can trust.

Whether you are setting up a purge line for stainless steel pipe welding, configuring a bulk gas system for a robotic cell, or simply adapting a unique piece of equipment, this bushing is a versatile problem solver. It represents the quality and reliability that Western Enterprises is known for in the welding industry. Keep your gas systems tight, safe, and efficient with this essential brass fitting.
