21597 - ESAB PT-25 Plasma Nozzle 100A - 5 Pack

Keep Your PT-25 Torch Cutting Clean

If you are running an ESAB PT-25 torch at 100 amps, you know that the nozzle is the business end of your operation. The ESAB 21597 Nozzle is the direct replacement tip you need to keep your machine cutting like new. This pack of five ensures you aren't left scrambling when a tip blows out in the middle of a job. We know that in the shop, downtime is money, and having fresh consumables on hand is the best way to keep the sparks flying and the metal separating.

Why is a fresh nozzle so important? Over time, the hole in the tip of your nozzle (the orifice) gets worn out. It might become oval-shaped, or it might get nicked by molten metal blowback. When this happens, your plasma arc loses its focus. Instead of a tight, hot stream that slices through steel like butter, you get a wide, wandering arc. This leads to ugly cuts, excessive dross (slag) that you have to grind off later, and angled edges that ruin your fit-up. By swapping in a fresh 21597 nozzle, you restore that tight, constricted arc, giving you clean, straight cuts that require less cleanup.

These nozzles are rated specifically for 100 amps. It is important to match your nozzle to your machine settings. Running 100 amps through a smaller nozzle will blow it out instantly, and running it through a larger nozzle will give you a weak, soft arc. These are precision-drilled for exactly 100A work, giving you the perfect balance of speed and quality. They are made from durable copper to withstand the intense heat of the plasma process, but like all consumables, they don't last forever.

Installation is quick and easy, fitting perfectly into your PT-25 assembly. Just unscrew the retaining cap, swap out the old nozzle (and check your electrode while you're at it!), and screw it back together. Make sure everything is snug to prevent gas leaks, but don't over-torque it. With this 5-pack in your toolbox, you are ready to tackle heavy plate cutting, fabrication, and repair work with confidence.
