Western Enterprises AW-15 Brass Adapter, 1/4" NPT Male x 5/8"-18 LH Female

Reliable Connections for TIG Water Coolers

Every TIG welder knows the importance of a reliable water cooling system. When you are pushing high amperage on aluminum or heavy steel, your torch needs consistent cooling to prevent overheating and failure. The Western Enterprises AW-15 Adapter is the piece of hardware that makes those vital connections possible. If you are setting up a new water cooler or replacing old, worn-out fittings on your welding cart, this brass adapter is the standard solution for converting your lines.

This specific adapter converts a standard 1/4" NPT Male pipe thread to a 5/8"-18 Left-Hand Female thread. You might ask, "Why the Left-Hand thread?" In the welding world, left-hand threads are often used for water and fuel gases to distinguish them from oxygen and inert shielding gases. This safety feature ensures you never accidentally hook your water line into your argon regulator or vice versa. Remember: with left-hand threads, it's "righty-loosen, lefty-tighten." This adapter ensures your water lines stay exactly where they belong.

Built from solid brass, this fitting is designed to withstand the rigors of the shop environment. It won't rust out from the water inside, and it stands up to the bumps and knocks of daily use. With a pressure rating of 200 PSI, it easily handles the pump pressure of standard industrial water coolers without breaking a sweat. The 3/4" hex body gives you plenty of grip for your wrench, allowing you to get that snug, leak-free seal that is crucial for keeping your shop floor dry and your equipment safe.

Whether you are plumbing a custom recirculation system or just need a replacement part for a leaky connection, this adapter is a must-have in your spare parts bin. It is also rated for industrial air, making it a versatile fitting for various pneumatic tools and laboratory setups. Don't let a missing $10 fitting shut down your production; keep your connections secure with Western Enterprises quality.
