Description of Cooling Adapter Welding Connector Fitting
Water-Cooled and Gas Adapter Quick Connector Fitting for PTA DB SR WP 9 17 18 26 TIG Welding torch. 1pcs Blue Color M8 Female Connector for M7 Hose. 1pcs Red Color M8 Female Connector for M7 Hose. 1pcs Gold Color M8 Female Connector for M7 Hose. 3pcs M6 Male Connector for M5 Hose.
I bought two of these to alternately connect my TIG/Plasma combo welder to argon or to my compressor, but the connectors to insert into the hoses are of different sizes making them unusable. The inner insert is 8mm and the male insert is 4mm.
If items are not listed do not specify items as included or show in photos. To top it all off, I absolutely needed plug connections at the time. I also used the complete set, which is also not included in this list.
