Western Enterprises AW-14 Brass Nut 5/8-18 LH Male CGA-033

Reliable Connections for Your Water-Cooled Gear

For professional welders running water-cooled TIG torches or plasma cutters, a leak is more than just an annoyance—it can stop production and damage expensive equipment. The Western Enterprises AW-14 Brass Nut is the exact replacement part you need to keep your coolant lines secure and your shop floor dry. Designed with a 5/8"-18 Left-Hand thread, this nut is specifically engineered for water hose connections and industrial air lines, ensuring you don't accidentally hook up your coolant line to a shielding gas regulator. The left-hand thread is a standard safety indicator in the industry, and this high-quality brass nut fits perfectly onto standard CGA-033 fittings.

Cheap fittings can crack under pressure or strip out after a few changes, but Western Enterprises is known for manufacturing robust brass parts that stand the test of time. Whether you are building a custom cooler setup, repairing a damaged torch lead, or simply replacing a rounded-off nut, the AW-14 provides the peace of mind that comes with a secure, pressure-rated connection. It handles up to 200 PSI, which is far more than most water coolers generate, giving you a reliable seal that won't fail in the middle of a critical weld.

Installation is straightforward with a standard 11/16" wrench. The hex edges are crisp and durable, allowing you to get the right amount of torque without slipping. Because it is made of solid brass, it resists rust and corrosion from the water or coolant mixture running through your lines. Don't let a worn-out fitting compromise your cooling system. Keep a few AW-14 nuts in your spare parts kit so you are always ready to fix a line and get back under the hood. This small but vital component ensures your focus remains on the puddle, not on a dripping hose.
