FUPA12 Replacement O-Ring

Kept a spare in my toolbox and finally needed it during a quick maintenance session — the seal seated snugly with no leaks on the first try. For the price, it’s a no-brainer to have a couple on hand.

The O-ring fit perfectly on my welding torch, restoring the seal instantly. It was exactly the right size and saved me from having to buy a whole new regulator setup.

I was relieved to find this O-ring because the original one on my torch had dried out and started leaking. The rubber is firm and flexible, which gave me confidence it would seat correctly in the groove. Fixed the seal on the first try without any trouble.
