Back Cap Medium WP17,18,26 [57Y05]

Description

The Parweld 57Y05 is a premium medium back cap designed for standard WP17, WP18, and WP26 series TIG welding torches. It serves as an essential consumable component, tightening down onto the torch head to apply force against the collet. This action locks the tungsten electrode firmly at the desired depth while providing a secure rear seal that prevents atmospheric air from leaking into the torch and contaminating the weld pool.

Key Specifications

• Torch Compatibility: Directly fits all 17, 18, and 26 series air-cooled and water-cooled TIG torches, including standard and Pro-Grip configurations.
• Component Length: 48mm (approx. 1.9 inches), providing an ideal intermediate size that balances torch maneuverability in tighter spaces with the ability to house mid-length tungsten electrodes.
• Airtight Sealing: Features a pre-installed, high-temperature rubber O-ring to ensure gas-tight containment of shielding gases like Argon.
• Material Composition: Constructed from robust, heat-resistant polymers with durable brass threads to prevent cross-threading and withstand prolonged high-amperage welding cycles.
