Description

Tigmaster Back Cap (Medium) Series 17, 18 & 26 (PK5) – 57Y05

Secure Tungsten Retention for TIG Welding

The Tigmaster 57Y05 medium back cap secures the tungsten and collet assembly inside the TIG torch head. As a result, it maintains correct consumable tension and helps ensure stable arc performance during welding.

Suits WP17, WP18 and WP26 TIG Torches

This back cap fits standard Series 17, 18, and 26 TIG torches commonly used across fabrication, maintenance, and industrial welding applications. In addition, it works with both standard collet body and gas lens consumable setups.

Medium Length for Better Balance and Access

The medium back cap provides a balance between torch clearance and tungsten support. Consequently, it offers improved access in tighter weld areas while still accommodating longer tungsten electrode lengths than a short cap.

Helps Maintain Stable Consumable Alignment

By applying consistent pressure to the collet system, the back cap keeps the tungsten securely centred within the torch assembly. Therefore, welders achieve improved arc stability, accurate tungsten positioning, and more consistent weld quality.

Durable Heat-Resistant Construction

The back cap uses durable insulating materials designed to withstand regular TIG welding temperatures and workshop use. As a result, it maintains reliable sealing and consumable retention over repeated welding cycles.

Ideal for General TIG Welding Applications

The 57Y05 medium cap suits stainless steel fabrication, aluminium welding, pipework, maintenance repairs, and general workshop TIG applications. Furthermore, it supports both precision work and everyday fabrication tasks.

Pack of 5 for Workshop Convenience

This PK5 pack provides multiple replacement back caps for routine torch maintenance and consumable servicing. Consequently, workshops can minimise downtime and keep spare components readily available.

Essential TIG Torch Consumable Component

Back caps experience wear through heat exposure, thread use, and repeated consumable changes. Therefore, replacing worn caps helps maintain proper torch sealing, tungsten retention, and reliable welding performance.
