KP2036-2B1 - Lincoln Electric Short Back Cap for 9/20 Series TIG Torches

Genuine Lincoln Electric TIG Torch Consumable

The Lincoln Electric KP2036-2B1 is a premium replacement back cap designed for use with standard air-cooled and water-cooled TIG torches. Specifically engineered for the PTA-9, PTA-20, and PTW-20 series torches, this component is critical for the proper assembly and function of your welding equipment. As a genuine OEM part, it guarantees the precise thread pitch and dimensional accuracy required to prevent damage to your torch head.

This specific model is the "Short" version, identified by the KP2036 series. Back caps serve two primary functions: they apply pressure to the collet to lock the tungsten electrode in place, and they seal the back of the torch head to prevent shielding gas from escaping. The KP2036-2B1 comes pre-fitted with a durable O-ring that ensures a positive seal, maintaining the integrity of your shielding gas coverage and preventing atmospheric contamination of the weld pool.

Constructed from high-temperature phenolic compounds and reinforced with brass threads, this back cap is built to resist the thermal cycling and mechanical stress typical of industrial welding environments. It is an essential inventory item for fabrication shops utilizing Lincoln Electric TIG equipment, ensuring that operators can adapt their torch configuration to suit specific joint geometries and access requirements.
