  • RADNOR™ Model 67002748 MIG Gun Liner

    Airgas Part #:RAD64002748

    Manufacturer Part #:67002748

Item Details

  • The Tweco (ESAB) 44 Series Universal MIG Conduit Liner is a heavy-duty, infrastructure-grade steel wound conduit engineered to guide large-diameter welding wire from the wire feeder drive rolls through the torch cable assembly to the contact tip. It is constructed from zinc-plated MB-grade spring steel wire with a machined solid brass alloy anchor block and a universal crimped wire guide sleeve to ensure concentric wire handover and minimize feeding friction.

Features

  • Universal Compatibility Architecture: Pre-installed crimped universal adapter profile fits multiple industrial MIG gun brands
  • Low-Friction Internal Channel: Zinc-plated spring wire reduces current load on wire feeder motors and eliminates pulsations
  • Round-Wire Coiled Spring Profile: Provides flexible bending strength without kinking at extreme torch neck angles
  • Debris Clearance Channel: Coiled configuration allows micro-debris and copper flakes to settle below the wire path to prevent clogging
  • Thermal Deflection Stability: Heavy steel wound structure acts as a heat sink to absorb radiant heat from high-amperage spray transfer
  • Roll-Stamped Identification: Permanent part number tracking stamped onto the outer circumference of the brass stop block
  • Concentric Wire Handover: Crimped guide sleeve ensures exact alignment from the liner into the gas diffuser or contact tip
  • Corrosion Resistance: Sacrificial zinc layer prevents oxidation in damp shop environments
