Stella X. ★★★★★ Oct 13, 2026

Swapped the short cap out for the long one so my tungsten sticks out further on deep joint welds. Threads lined up clean on my 20 series torch, no cross-threading at all.

Michael Y. ★★★★★ Sep 15, 2026

Ordered the medium back cap for my WP-9 and it threads on smooth with no leaks. The short one gives me way better access in tight corners on thin stainless.

Bought the medium back cap to replace a stripped one on my older torch. It threaded on smoothly and feels solid, though the gas seal isn't quite as tight as the original. Works fine for my daily use though.
