Western Enterprises WES33 Brass Regulator Adaptor 1/4 NPT x 9/16-18 LH

Essential Regulator Outlet Bushing for Fuel Gas Setup

Maintain the integrity and safety of your oxy-fuel welding equipment with the Western Enterprises WES33 Regulator Outlet Bushing. This robust brass adaptor is an indispensable part for welders needing to connect a regulator with a 1/4-inch NPT port to a standard B-Size fuel gas hose. In the world of welding, "B-Size" fittings (9/16"-18 threads) are the most common connection type for industrial hoses, torches, and regulators. This bushing bridges the gap between the internal pipe threads of the regulator body and the external hose connection, ensuring your gas flows smoothly and safely to your torch.

Designed specifically for Acetylene and other fuel gases, the WES33 utilizes Left-Hand (LH) threads on the outlet side. This is a crucial safety feature that distinguishes fuel gas fittings from oxygen fittings (which use Right-Hand threads), preventing cross-connection that could lead to dangerous flashbacks or explosions. The bushing is machined from solid brass, offering excellent resistance to corrosion and wear, which is vital in shop environments where equipment is exposed to heat, sparks, and rough handling. The 5/8-inch hex shape provides a solid grip for your wrench, ensuring you can tighten the NPT side securely into the regulator body without stripping the edges.

This adaptor is not just a replacement part; it is an upgrade in reliability. Cheap or worn fittings can lead to gas leaks, which are both costly and hazardous. By using a high-quality Western Enterprises fitting, you ensure a tight, consistent seal. The component is rated for up to 200 PSIG, making it suitable for a wide range of fuel gas applications including brazing, cutting, and heating. Whether you are refurbishing an old regulator or building a custom kit, the WES33 ensures your connections meet industry standards for safety and performance.

Application Notes:

• Always use an approved thread sealant or PTFE tape on the 1/4" NPT threads during installation to ensure a gas-tight seal.
• Do not use sealant on the 9/16"-18 LH threads; the seal is made by the metal-to-metal contact of the hose gland.
• Verify that your regulator is designed for fuel gas service before installing this left-hand threaded adaptor.
