ESAB PKB 250/400 Torch Connection Box Assembly

Fix Your Rig with Genuine ESAB Parts

If you are running an ESAB setup with a PKB 250 or PKB 400 torch system, you know that the connection point is the lifeline of your welder. When that connection gets sloppy, cracked, or worn out, your entire day can grind to a halt. The ESAB Torch Box PKB 250/400 (0161337076) is the exact replacement part you need to swap out a damaged housing and get your machine running like new again. Don't struggle with duct tape fixes or loose connections that mess up your gas coverage; replace the box and weld with confidence.

This isn't a cheap knock-off; it's the real-deal OEM part from ESAB. That means it fits exactly where the old one came off, with no modification needed. Whether you cracked the old box moving the feeder around the shop or it just finally gave up after years of heat and abuse, this replacement will restore that solid, "click-in" feel you expect from professional equipment. A solid torch connection means consistent wire feed speed and no gas leaks, which translates to better beads and less frustration.

Installation is straightforward for anyone familiar with maintaining their gear. Simply disconnect the power, remove the old housing, and bolt this one in place. It is built to handle the amps and the heat of the PKB 250 and 400 series, so you don't have to worry about it melting down in the middle of a long pass. Keep your downtime short and your arc smooth by keeping your machine's hardware in top shape.
