56Y40 - ESAB HW-90 Long Back Cap 56Y40 (Pack of 2)

Keep Your HW-90 Running Smoothly

If you are still rocking the classic HW-90 TIG torch, you know that finding the right parts can sometimes be a hunt. The ESAB 56Y40 Long Back Cap is the exact replacement you need to keep your torch operational and your welds clean. This isn't just a piece of plastic; it's the seal that keeps your expensive shielding gas flowing where it should—over the weld puddle—and not leaking out the back of your handle.

Why choose the long cap? It's all about economy and convenience. With this Long Back Cap, you can slide in a fresh, full-length 7-inch tungsten electrode right out of the box. There is no need to snap or grind your tungsten in half just to make it fit, which saves you time and reduces waste. The cap is made from durable, heat-resistant material that stands up to the radiant heat of heavy amperage welding, ensuring it won't warp or crack easily under normal use.

We sell these in a convenient 2-pack because we know how it goes—sometimes you drop one, step on it, or the threads finally give out after years of service. Having a spare in your toolbox means you never have to stop a job halfway through just because of a cracked cap. Restore the performance of your HW-90 with genuine ESAB parts.
