I maintain a few former rental guns for a friend of mine. Mostly old spyder TL's. A few shredded some o-rings recently, so I went through and replaced them all with some 015 buna o-rings. I've used these many times on my guns with no problems, but I've noticed on the TLs it seems to cause excessive blowback and has been breaking balls in the hopper. I replaced the striker o-ring on 2 of them with actual kingman #19A urethane o-rings, and it fixed the issue. Unfortunately, I still have about 10 guns to go, and the cheapest I could find these things is $1.50 apiece plus shipping. Not too bad, honestly, if I were fixing 1 or 2, but I'd like to replace them all and have spares for all of them. Anybody know a place to get these in bulk? Needs to be the urethane ones, the buna rings arent cutting it for some reason on these guns.
I have the dimensions from the archived otter site, but does anyone know what durometer they are? I was thinking maybe 70, but some threads seem to suggest they're 90! Thanks for the link btw, but I wish they'd be a bit better about the description. Is it 4 #19A and 3 others, or are they all #19As with 3 different colored ones. Confusing, lol

I have buna 015 70s in them right now, I have 90s that I was thinking of trying too, but haven't yet. I went ahead and ordered some o-rings from punisherspb.com for $1.50 apiece, best prices could find on real urethane #19As
