O-ring kits at Orings-Online

[Self Medicated]

Just discovered orings-online.net! Had no idea it even existed. I'm sure most people here know about it. I was just super excited because I recently dug out all my gear after 20 years and was looking to replace all the o-rings on my markers.

That's the go-to for eBay o-rings as far as I know, been reliable for me.

I use "The O-Ring Store".

Absolutely fantastic for the weird stuff like quad rings or 70-durometer urethane or metric 3 in silicone or #010 in Teflon.

They seriously have it all.

^ I agree. If you know the sizes this is the way to go. Actually placed an order last night.
