Review on 🔥 Enhance Welding Efficiency with RIVERWELD TIG Back Caps (Long, Medium, Short) - 41V24, 41V35, 41V33: Compatible with SR PDA DB WP 9 20 25 TIG Welding Torch - 10pcs Pack by Romas Pennington

I've used a few and have no complaints. One minor point though: I wish they came with extra O-rings. Everyone knows that if you weld at high amperage for a period of time these things will never come out right after you remove them. It would make this set better. But otherwise I'm satisfied.
