Has anyone had an issue using only Buna-N O-rings, instead of using silicone for the gas posts?

I use regular Buna-N o-rings for both posts. They work fine. Haven't had many issues as long as the QDs aren't being shifted to the side.

good to know, thanks! I just hate to spend the money on silicone and have 200 post orings if I can jsut use the Buna-N only. I know that probably sounds cheap, but that's less money I can spend on beer haha

One more question on these o-rings. Does anyone know a part number for the replacement o-rings for universal poppets? I know that they can be replaced, I just can't find it anywhere what orings those would be.

Measure the cross section then the ID an use this chart or the Parker oring handbook which is the oring bible.

I just ordered this whole lot and everything checks out perfectly on my ball-locks, really helpful thread guys, thanks!

Also a huge kudos on McMaster Carr's delivery, less than 18 hours from order!

I haven't used them yet, but I ordered #008 Silcone Orings for my universal poppets based on recommendations from an HBT thread discussing these. Mcmaster part number 9396K13.

Anyone have any idea what the part number for this oring might be? It is the oversized one for leaky kegs.

Has anyone ever used these for the lid? They are only 3/16s cross section, but they are quad seals. Maybe they will be better for a leaky keg.

or these yellow ones? I read they may be softer and larger.
