HARFINGTON 5-Pack TIG Back Cap 57Y04 For WP-17, WP-18, WP-26 Welding Torch Replacement

About This Product

Welders, this 5-pack of HARFINGTON TIG back caps is exactly what you need to keep your welding torch in top working condition. These are 57Y04 model back caps specifically designed as replacement parts for WP-17, WP-18, and WP-26 series TIG welding torches. The construction is solid - made from copper and plastic materials that provide long service life, high resistance, and pressure resistance during welding operations. Each back cap measures 25mm (0.98 inches) in total length with a 9.3mm (0.37 inches) diameter, which is the standard size for these torch models. The copper material offers good ductility and abrasion resistance, while the plastic components ensure comfortable handling during extended welding sessions. These back caps securely attach to your TIG torch head body, ensuring proper fit and effective performance while you're working. It's important to match the appropriate back cap size with your tungsten electrode length for optimal performance and safety. These are suitable for use in various settings including workshops, manufacturing facilities, construction sites, and other industrial environments where TIG welding is performed. The 5-pack is super convenient because back caps can wear out over time, and having spares means less downtime when you need to replace one. Regular inspection of your back caps for wear or damage is good practice, and replacing them as needed helps maintain welding efficiency and safety. Whether you're a professional welder who needs reliable replacement parts or a hobbyist keeping your equipment in good shape, these HARFINGTON back caps deliver the quality and compatibility you need for smooth TIG welding operations.
