Best Welds 900-22-10 Tig Cup Gasket 22A 22B Torches

Product Description

The BEST WELDS 900-22-10 is a TIG cup gasket and insulator designed to seal the connection between the TIG torch body and the gas lens or collet body cup. This gasket maintains a consistent gas shield around the tungsten by preventing air infiltration at the cup-to-torch interface. It is a direct-fit, OEM-style replacement component suited for TIG welding applications in fabrication shops, maintenance facilities, and field service environments. Welders and welding equipment technicians install this part as part of routine torch maintenance or when rebuilding a torch that has developed gas leaks at the cup seat.

This cup gasket is designed for use with 22A and 22B series TIG torches. It is a small-profile component appropriate for the torch body sizes common in light-duty to medium-duty TIG setups. Replacement is typically required when the existing gasket shows cracking, distortion from heat exposure, or loss of sealing capacity that results in inconsistent arc starts or porosity in the weld bead caused by atmospheric contamination of the shielding gas envelope.

Key Features

• Direct-fit replacement cup gasket for 22A and 22B TIG torches
• Seals the cup-to-torch interface to maintain shielding gas coverage
• Compact small-group sizing for standard 22-series torch bodies
• Non-hazardous material with no Prop 65 designation
• Suitable for routine torch maintenance and torch rebuild kits

Compatibility

Designed for use on 22A and 22B series TIG torches as stated by the manufacturer.

Installation Notes

Installation should be performed by a qualified welder or welding equipment technician. Before replacing the cup gasket, disconnect the torch from the power source and shut off the shielding gas supply at the regulator. Seat the gasket fully against the torch body before threading on the cup to avoid pinching or uneven compression. Inspect the cup threads and seating surface for damage before reinstalling to ensure a proper seal.
