0151271001 - ESAB PKB 315/400 Replacement MIG Gas Nozzle

Keep Your PKB Torch Running Smoothly

Every welder knows that the front end of the MIG gun takes the most abuse. Between the intense heat of the arc and the constant spray of spatter, your gas nozzle is the first line of defense and a key player in weld quality. This genuine ESAB Gas Nozzle (0151271001) is the direct replacement for your PKB 315 or PKB 400 MIG torch. If you are noticing porosity in your welds or if your current nozzle is so battered that it's disturbing your gas flow, it is time for a swap.

A fresh nozzle does more than just look good; it ensures your shielding gas is covering the puddle exactly where it needs to. When nozzles get clogged with spatter or the edges get ragged from banging them against the table to clear them out, the gas flow becomes turbulent. That turbulence pulls in air, and suddenly you are fighting wormholes and soot in your bead. This ESAB nozzle is built tough with heavy-duty copper to handle the heat of high-amperage welding without melting or deforming. It fits snugly onto your PKB torch, ensuring no gas is wasted leaking out the back.

Maintenance is straightforward. Because it is made of high-quality copper, it resists spatter buildup better than cheaper knock-offs. When spatter does stick, a quick dip in nozzle gel or a scrape with your MIG pliers usually cleans it right up. This nozzle is designed for standard welding applications, giving you good visibility of the puddle while providing a wide enough umbrella of gas to keep things clean. Whether you are fabricating structural steel or doing repair work in the shop, keeping a few of these spares in your toolbox ensures you aren't shut down by a $20 part.

Don't compromise your weld quality with ill-fitting generic parts. This nozzle is made by ESAB for ESAB torches, meaning you won't have to fight to get it on or worry about it falling off in the middle of a bead. It’s a simple, reliable solution to keep your arc stable and your welds passing inspection.
