Esab 0365310050 Medium Tig Torch Cap with O-ring

Product Description

The ESAB 0365310050 is a medium TIG torch cap with an integrated O-ring, designed as a consumable collet body back cap for water-cooled and air-cooled TIG welding torches. The cap seals the rear of the torch body, protecting internal components from contamination while securing the tungsten electrode in place during operation. It ships individually and is intended for use by licensed welding professionals and skilled tradespeople performing GTAW (TIG) welding work. The long cap style accommodates standard-length tungsten electrodes and the included O-ring ensures a proper pressure seal at the torch rear.

This cap is suited for light industrial and professional TIG welding applications where torch integrity and consistent tungsten retention are required. It is compatible with the HW-20 and HW-20A torch models, making it a direct-fit replacement for worn or damaged back caps on those units. Typical install scenarios include routine consumable replacement during torch maintenance on both shop and field welding setups.

Key Features

• Medium cap style with long cap configuration for standard tungsten length clearance
• Includes pre-fitted O-ring for a positive rear seal on the torch body
• Direct OEM-style replacement for worn or cracked TIG torch back caps
• Lightweight construction at 0.025 pounds for minimal torch balance impact
• Compatible with HW-20 and HW-20A torch models

Compatibility

Designed for use with the HW-20 and HW-20A TIG welding torches. Consult your torch documentation to confirm cap thread size and collet body fitment before installation.

Installation Notes

TIG torch consumable replacement should be performed by a qualified welder or welding equipment technician. Disconnect the torch from the power source and allow it to cool completely before handling any torch components. Thread the back cap in by hand until snug, taking care not to cross-thread or overtighten, which can damage the torch body threads. Inspect the O-ring for damage before installation and replace it if cracking or deformation is present.
