Item Details
- The ITW Miller Weldcraft QRW is a quick-release water coupler kit designed for water-cooled TIG welding systems. It features a machined brass construction with a stainless steel ball-bearing locking mechanism to facilitate rapid, tool-free connection and disconnection of coolant hoses. The system includes a single shut-off valve to prevent coolant leaks during disconnection and utilizes industry-standard 5/8"-18 left-hand threads to ensure safety and compatibility with industrial water coolers and TIG torches.
Features
- Tool-free rapid connection and disconnection after initial installation
- Integrated single shut-off valve prevents coolant loss and leaks when disconnected
- Safety-coded left-hand threads prevent accidental cross-connection with shielding gas lines
- Spring-loaded sleeve mechanism for positive locking
- Reduces mechanical wear on machine manifold threads by remaining permanently installed
- Corrosion-resistant brass construction for industrial environments
- Facilitates faster torch changes and simplified cable storage
