0558004878 - ESAB PT-37 50 Amp Replacement Plasma Nozzle

Keep Your Torch Running with ESAB PT-37 50A Nozzles

There is nothing more frustrating for a welder or fabricator than having a plasma cutter go down in the middle of a job. When your cut quality starts to degrade—when you see excessive dross, a wandering arc, or a beveled edge that shouldn't be there—it is usually time to check your consumables. The ESAB PT-37 50A Nozzle is the direct replacement part you need to get your ESAB PT-37 torch back to peak performance. Sold in convenient packs, these nozzles are the frontline defense against poor cuts and wasted metal.

Plasma cutting relies on a focused stream of superheated gas to melt through metal, and the nozzle is the funnel that makes that happen. This specific nozzle is rated for 50 Amps, making it the perfect choice for general-purpose cutting on a variety of conductive metals. It is designed to handle the heat and pressure of a 50-amp arc, providing a clean, narrow kerf that reduces the amount of material wasted. Because the nozzle is right next to the molten metal, it takes a beating from heat and spatter. That is why ESAB uses durable copper construction to extend the life of the part, giving you more cuts for your money.

Why choose genuine ESAB parts? It comes down to fit and safety. Generic or "knock-off" consumables often lack the precise machining of OEM parts. A poorly fitting nozzle can cause gas leaks, arcing inside the torch, or even catastrophic failure of the torch head. With these genuine ESAB nozzles, you are guaranteed a perfect fit every time. They screw on easily and seat correctly against the electrode and swirl ring, ensuring the electrical and gas connections are secure. This means you spend less time troubleshooting your machine and more time cutting parts.

We recommend keeping a fresh pack of these 50A nozzles in your toolbox or supply cabinet. Consumables are wear items—they are meant to be replaced. Trying to stretch the life of a worn nozzle usually ends up costing more in grind time and reworked parts than the cost of a new tip. Whether you are working on automotive restoration, HVAC ductwork, or general shop fabrication, a fresh nozzle is the secret to a professional-looking cut. Don't let a $10 part ruin a $100 sheet of steel; swap out your worn nozzle with a genuine ESAB replacement and keep the sparks flying.
