998739 - Esab 1566HS-8 MIG Gun Nozzle, 1/2 Inch Bore

Restore Your Torch's Performance

If you are running an Esab ST-23 or MT-200 MIG gun, you know these torches are built to last, but even the best equipment needs fresh consumables to perform at its peak. The Esab 1566HS-8 MIG Nozzle (SKU: 998739) is the genuine replacement part you need to keep your welds clean and your arc stable. A worn or battered nozzle can lead to inconsistent gas coverage, resulting in frustrating porosity and weak welds. Swapping out your old nozzle for a fresh 1566HS-8 is a quick and easy maintenance step that pays off immediately in weld quality.

This nozzle features a 1/2-inch bore (size #8), which is the "goldilocks" size for most general fabrication work. It provides a wide enough umbrella of shielding gas to protect the molten puddle while still being narrow enough to get into tighter joints and corners. Whether you are welding mild steel, stainless, or aluminum, having a clean, un-dented nozzle is the first line of defense against weld defects. The copper construction effectively pulls heat away from the front end of your gun, helping to extend the life of your contact tips and insulators.

Don't settle for generic knock-offs that might not fit quite right or rattle loose during a long bead. This OEM Esab part is designed to snap or screw onto your specific torch model perfectly, ensuring the gas flows exactly where it's supposed to. Keep a few of these in your toolbox so you are never caught off guard by spatter buildup or accidental damage. With the 1566HS-8, you can trust that your equipment is ready to handle whatever the job throws at it.
