Pro-source 18CG Tig Torch Cup Gasket for Torches 17 18 26

Product Description

The PRO-SOURCE 18CG is a replacement cup gasket designed for TIG welding torches. It seats between the ceramic or glass cup and the torch body, maintaining a secure, gas-tight connection that supports proper shielding gas flow during the weld. At 0.800 inches in length, this gasket is a compact but critical consumable that directly affects weld quality and torch performance. Welders and fabricators replace these as part of routine torch maintenance whenever a cup shows signs of gas leakage or the gasket shows wear, cracking, or deformation from heat exposure.

This cup gasket is intended for use with torch models 17, 18, and 26 — three of the most widely used air-cooled TIG torch series in professional welding shops, maintenance facilities, and fabrication environments. It is a direct-fit replacement that keeps a torch running without interruption on the bench or in the field. Sold individually, it suits both single-replacement needs and stocking as a shelf spare.

Key Features

• Fits TIG torch series 17, 18, and 26 for broad torch compatibility
• 0.800-inch length matches OEM cup gasket dimensions
• Maintains a gas-tight seal between the cup and torch body
• Supports consistent shielding gas coverage at the weld zone
• Sold as a single unit for targeted replacement or stocking

Compatibility

Designed for use with TIG torch models 17, 18, and 26 as stated by the manufacturer.

Installation Notes

Cup gasket replacement is performed by qualified welders or torch service technicians. Before servicing, disconnect the torch from the power source and ensure the shielding gas supply is shut off at the regulator. Remove the existing cup, extract the worn gasket, seat the new gasket squarely in the torch body recess, and reinstall the cup hand-tight. Verify there are no gas leaks before resuming welding operations.
