Back Cap Long WP17,18,26 [57Y02]

Description

57Y02 (Long Back Cap) is a standard, industry-wide TIG torch consumable designed to apply pressure to the collet, locking the tungsten electrode firmly into position while creating an airtight atmospheric seal at the rear of the torch head. Built with a premium composition of high-temperature polymer housing and a durable brass core, it provides the thermal resistance and structural integrity necessary for industrial fabrication.

Key Features

• Airtight Gas Seal: Prevents atmospheric contamination and oxygen entry at the rear of the torch head to preserve shielding gas purity.
• Full-Length Tungsten Storage: Extended long-cap profile allows for the insertion of full-length (175mm) tungsten electrodes without needing to cut them down.
• Thermal & Pressure Resilience: Engineered with a specialized high-impact polymer outer shell coupled to a robust brass thread to prevent stripping and resist high operational heat.
