OVERVIEW

Keep Your TIG Torch Running with the Weldcraft 41V24 Long Back Cap

Every TIG welder knows the frustration of a cracked back cap or a stripped thread right in the middle of a job. The Weldcraft 41V24 Long Back Cap is the standard replacement for your WP-9 or WP-20 torch, and this 2-pack ensures you always have a backup in your toolbox. Designed to hold full-length 7-inch tungsten electrodes, this long cap lets you get the most out of your expensive tungsten without having to cut it down prematurely.

Whether you are running a light-duty air-cooled 9 series torch in the garage or pushing a water-cooled 20 series torch to its limits on stainless pipe, this back cap is built to handle the heat. It is made from durable, high-impact material that resists cracking if dropped—a common occurrence in busy shops. The O-ring comes pre-installed and provides a tight seal, ensuring your expensive Argon goes exactly where it's supposed to: over the weld puddle, not leaking out the back of your handle.

Why choose the Long Cap?
While short and medium caps are great for tight spaces, the long cap is the daily driver for most bench work and open-space fabrication. It provides a comfortable balance to the torch and allows you to use fresh, long tungsten rods straight out of the box. The knurled or textured end makes it easy to tighten and loosen by hand, even when wearing TIG gloves, allowing for quick tungsten adjustments on the fly.

This package contains two genuine Weldcraft caps. Using genuine parts means you don't have to worry about the cap not threading in smoothly or the O-ring being the wrong size. It fits perfectly on Miller, Weldcraft, Lincoln, and most other major brands of 9/20 style torches. Don't let a $5 part stop a $500 job—keep a few 41V24 caps in your kit and keep welding.

FAQ

The 41V24 fits 9 Series (air-cooled) and 20 Series (water-cooled) TIG torches, including models WP-9, WP-20, HW-20, and HW-20A.

Yes, each 41V24 back cap includes the necessary O-ring to ensure a gas-tight seal with the torch body.

It is manufactured from a high-impact, heat-resistant polymer designed to withstand the thermal stress of welding environments.

Yes, the 'Long' designation means it is designed to accommodate standard 7-inch (175mm) tungsten electrodes.

Back caps can crack if dropped or threads can strip over time. Having a spare ensures you don't have downtime during a project.

While it is a genuine Miller/Weldcraft part, it is compatible with most industry-standard 9 and 20 series torch bodies from other brands.

Use a long cap (41V24) for standard 7-inch tungsten. Use medium or short caps if you are welding in a tight space where the long cap would obstruct the torch angle.
