Miller 5/8" Left Hand Thread to Quick Release Adaptor - WK-2
The WK-2 Miller 5/8" Left Hand Thread to Quick Release Adaptor provides a simple and reliable solution for connecting TIG welding torches fitted with a standard 5/8"-18 left-hand thread to welding machines equipped with a quick release water connection. Designed as a direct conversion adaptor, it eliminates the need to modify existing torch hoses while allowing fast connection and disconnection during machine changes or routine maintenance.
Manufactured from high-quality precision machined brass, the WK-2 adaptor offers excellent durability, corrosion resistance and leak-free performance in demanding industrial welding environments. It is suitable for both workshop and production use where reliability and ease of use are essential.
Designed for Miller TIG Welding Equipment
This adaptor is commonly used when fitting TIG torches to compatible Miller welding power sources that utilise a quick release water connection. The female 5/8"-18 left-hand thread accepts the standard 'B' size water hose fitting found on many water-cooled TIG torch assemblies, while the quick release male fitting allows rapid connection to the machine. :contentReference[oaicite:0]{index=0}
