OVERVIEW

Professional Grade Replacement TIG Torch O-Rings

Maintain the integrity of your TIG welding equipment with this pack of 14K11 O-Rings. These industry-standard seals are engineered to fit the back cap assembly of 9, 17, 18, 20, and 26 series TIG torches. They serve as the final barrier against gas leakage, ensuring that your shielding gas flows directly to the nozzle without escaping through the back of the torch handle.

Measuring 0.100 inches in Inner Diameter (ID) and 0.070 inches in Cross Section, these O-rings meet the exact specifications required by major torch manufacturers such as Weldcraft, CK Worldwide, and Profax. They are an essential maintenance item for any welder experiencing unexplained gas coverage issues or audible hissing from the torch handle.

Technical Specifications

Constructed from high-grade rubber material, these O-rings offer excellent resilience and compression set resistance. They are designed to withstand the thermal cycling inherent in welding operations without becoming brittle prematurely. This pack contains five (5) O-rings, providing an economical solution for routine maintenance schedules.

  • Short Back Caps (Button Caps)
  • Medium Back Caps
