Welding accessories, that even hobby welders can afford.
These purge kits are designed to achieve a perfect sealing surface against your weldment. Even if your tube or pipe is slightly out of round. A leaky inlet plug will pull air and contaminate your argon before it even has a chance to shield the weld. Each plug comes with a multi layer stainless steel diffuser for eliminating turbulence inside the tube/pipe while maximizing the efficiency of argon consumed.
Quit wasting gas, make better welds!
HT silicone is rated to 600 Fahrenheit
Not designed for welds within 1” of plug (depending on amperage and travel speeds)
