430-420365 - Hypertherm XPR Nozzle Retaining Cap 420365

Reliable Parts for Your XPR System

Keep your automated cutting table running at peak efficiency with the Hypertherm 420365 Nozzle Retainer. Designed specifically for the XPR170 and XPR300 plasma systems, this cap is the nut and bolt operation that holds your torch's business end together. When you are running high-volume production, you need consumables that fit right the first time and hold up under heat. This genuine Hypertherm retaining cap ensures your nozzle stays perfectly centered, which is exactly what you need for clean, dross-free cuts that reduce secondary grinding operations.

We know that in a busy shop, torch parts take a beating. The nozzle retainer is often the first line of defense against reflected heat and spatter. While it is a durable part, threads can wear out over time, and o-ring sealing surfaces can get scratched during hurried changeovers. Replacing your retaining cap with a fresh 420365 ensures a tight gas seal and proper electrical contact, preventing costly torch errors or mid-cut shutoffs. It is a small investment that protects the more expensive torch body and ensures your expensive consumables (nozzles and electrodes) last as long as they are rated to.

Don't risk your cut quality with generic knock-offs that might not thread correctly or could melt under the XPR's high power. Stick with the OEM 420365 Nozzle Retainer to maintain the factory-spec performance of your Hypertherm machine. Whether you are cutting thick plate or precision parts, this retainer is essential for a stable, consistent arc.
