The RADNOR 64005965 is a TIG gas lens insulator gasket, industry standard reference 57N56, designed for Gas Tungsten Arc Welding (GTAW). It functions as a thermal, electrical, and pneumatic barrier within the torch head assembly, specifically engineered to adapt large gas lens configurations onto compatible torch bodies and provide a seal for large-diameter ceramic nozzles.
Features
Shielding Gas Sealing: Prevents ambient air aspiration into the torch head and ensures laminar gas flow through the gas lens mesh.
Spatter Resistance: Low-surface-energy PTFE material resists adhesion of welding spatter and airborne particulates.
Thermal Barrier: Redirects radiant heat away from internal brass threads of the torch head to prevent premature failure.
High-Frequency (HF) Arc Stabilization: Prevents current leakage to ground to ensure reliable arc ignition.
Mechanical Interface: Precision-machined internal seating groove locks over the torch body for flush mating with large gas lens ceramic cups.
