0558009301 - ESAB PT-36 Water Injection Cup Insert

Keep Your PT-36 Cutting Clean and Cool

If you are running an ESAB PT-36 torch, you know that water injection is the secret sauce for getting those laser-like cuts on aluminum and stainless steel. But that system relies on tight seals and perfect flow to work right. The ESAB 0558009301 Cup Insert is the genuine replacement part that sits inside your torch head, guiding that water exactly where it needs to go. Over time, heat and pressure can wear these inserts down, leading to sloppy cuts or, worse, water leaking where it shouldn't be. Don't let a worn-out piece of plastic compromise your expensive equipment.

This cup insert is built tough to handle the extreme environment inside a plasma torch. It fits perfectly into the PT-36 assembly, ensuring that the water swirls around the arc just right to squeeze it tight. That constriction is what gives you that clean, square edge and keeps your dross to a minimum. When you use genuine ESAB parts like this, you aren't just swapping out plastic; you are resetting your machine's performance back to factory standards. It installs easily and seats securely, so you can get back to cutting without worrying about leaks or arc errors.

We know that in a busy shop, downtime is the enemy. Waiting for a technician to diagnose a bad cut quality issue costs money. Often, the fix is as simple as refreshing your consumables. If you notice your cut angularity drifting or your consumables burning up faster than usual, check your cup insert. Keeping a few of these 0558009301 inserts on the shelf means you are ready to swap and go, keeping your production line moving and your cuts looking sharp. Trust genuine ESAB parts to protect your torch and your bottom line.
