ISO O-rings that aren't garbage

[DevilEyeDog]

Two purchases off of Amazon has found me with a bunch of o-rings that are garbage. By this I mean they don't work and my tank continues to leak. One set is hard as a rock and the other simply doesn't fit my yoke adaptor on my steel tanks. Looking for recommendations for good o-rings. TIA

I buy almost all my o-rings from McMaster-Carr O-Rings

Thanks. Ignorantly I have no idea what size of o-ring I need so I'll have to do some research on that. I'm used to buying the kits, but my last kit has failed me. Thanks again!

I buy most of my O-rings from The O-Ring Store LLC, We make getting O-Rings easy! or from Orings and More | Affordable and Quality Gaskets and Seals

never had an issue. Great prices, good quality, and they have about every size o-ring you can think of.

Also consider what duro you need. Those that see HP are recommended to be 90. For LP (intermediate pressure) 70 is generally recommended. It may be that those hard ones you got are right. They are just 90 for HP applications.
