0368002881 - ESAB PKB 400 Straight Swan Neck Replacement

Reach the Unreachable with the PKB 400 Straight Neck

Every welder knows the frustration of a joint you just can't reach. Maybe it's at the bottom of a deep pipe, inside a narrow box section, or requires a weird angle that your standard 45-degree or 60-degree goose neck just can't handle. That is exactly where the ESAB Straight Neck for the PKB 400 comes into play. This isn't just a spare part; it's a problem solver. Designed to convert your standard PKB 400 MIG gun into a straight-shooter, this neck gives you the reach and direct line of sight needed for those tricky, hard-to-access welds.

Built with the toughness you expect from ESAB, this neck can handle the heat. The PKB 400 is a beast of a torch, and this neck is rated to keep up with it. Whether you are running hot spray transfer or pulsing in a tight corner, the insulation and conductor tube are engineered to resist thermal breakdown. The straight design is also a favorite for guys setting up simple mechanization—like mounting the gun on a carriage for a long longitudinal seam—where a curved neck would just get in the way or create an awkward wire feed angle.

Wire feeding is critical when you change neck geometries. A cheap neck will cause drag, bird-nesting, or erratic arcs. ESAB has machined the liner path in this straight neck to be perfectly smooth, ensuring your wire glides through without a hitch. This means less downtime clearing jams and more time burning wire. The gas coverage is also spot-on; the nozzle seat is precise, ensuring your shielding gas goes exactly where you point it, which is crucial when you are welding deep in a hole where atmospheric contamination is a risk.

Don't let a difficult joint geometry stop your production. Swapping out your neck takes just a minute, but the difference it makes in comfort and weld quality on specific jobs is massive. Keep one of these 0368002881 straight necks in your toolbox or locker. When that oddball job comes through the shop door, you'll be the one with the solution ready to go. It’s about having the right tool for the job, and sometimes, the right tool is a straight line.
