QRW - Weldcraft QRW Water Quick Connect Coupler Kit

Genuine Weldcraft QRW Water Quick Connect Coupler for TIG Coolers

The Weldcraft QRW Water Quick Release Kit is a premium plumbing accessory designed specifically for water-cooled TIG welding applications. This kit allows for the rapid connection and disconnection of water coolant hoses without the need for hand tools, making it an indispensable upgrade for Miller, Lincoln, and other major brands of water coolers and welding power sources.

Technical Specifications and Compatibility

This kit features standard Left-Hand (LH) water threads (typically 5/8"-18 LH), which are the universal standard for inert gas welding water connections. The use of left-hand threads acts as a safety coding system, physically preventing the cross-connection of water lines with shielding gas lines (which use right-hand threads). The kit consists of two main components:

• Male Nipple: Threads directly into the water output port of your welder or standalone water cooler.
• Female Quick Disconnect: Attaches to the end of your TIG torch's water inlet hose.

Robust Construction

Manufactured by Weldcraft (a Miller Electric brand), the QRW kit is engineered for reliability. The body is machined from solid brass, providing superior durability compared to plastic alternatives. The quick-release mechanism employs a spring-loaded sleeve and stainless steel ball bearings to ensure a positive lock. To disconnect, simply pull back the sleeve and the hose releases instantly. This design minimizes wear on the threads of your expensive equipment, as the threaded connection is made once and left permanently in place.

Application Notes

This coupler is ideal for use with side gas hose setups and standard water-cooled torches (such as the WP-18, WP-20, or CS310 series). It is rated to handle the pressure and flow rates typical of industrial welding coolant pumps. By installing the QRW kit, you facilitate easier maintenance, faster torch changes, and simplified storage of your welding cables. The secure seal prevents coolant loss during operation, maintaining the thermal efficiency of your cooling system and protecting your torch head from heat damage.
