Esab 0365310051 Long Tig Torch Cap HW-20 HW-20A

Product Description

The ESAB 0365310051 is a long-style TIG torch cap with an integrated O-ring, designed to secure the collet body and tungsten electrode in place during TIG welding operations. This cap threads onto the back end of compatible water-cooled or air-cooled TIG torch bodies, providing a gas-tight seal through the O-ring to maintain shielding gas integrity at the torch head. At 0.025 pounds, it is a lightweight consumable replacement part. TIG welders and welding maintenance technicians install this cap as part of routine torch consumable service.

This long cap is suited for applications where additional tungsten stick-out or a longer rear profile is preferred, which can improve visibility and access in tight weld joints. It is used with ESAB HW-20 and HW-20A TIG torch bodies in both shop and field welding environments. The long cap style is a common choice for pipe welding and precision fabrication where torch ergonomics and electrode positioning matter.

Key Features

• Long cap style provides extended tungsten support and improved torch access in tight weld joints
• Integrated O-ring creates a gas-tight seal to maintain shielding gas flow at the torch rear
• Lightweight design at 0.025 pounds minimizes added torch weight
• Direct replacement consumable for maintaining torch performance and weld quality

Compatibility

Designed for use with ESAB HW-20 and HW-20A TIG torch bodies.

Installation Notes

This cap is installed and serviced by qualified welders or welding equipment technicians. Before replacing the torch cap, shut off the shielding gas supply and ensure the welder power source is off. Thread the cap onto the torch body by hand until snug, taking care not to cross-thread or overtighten, which can damage the O-ring or torch body threads. Inspect the O-ring for wear or cracking during each cap replacement and replace it if any deformation is present.
