I'll bet your LHBS has one. The ones I have are nylon, and white/clear in color.

I read the the nylon ones aren't that great.

You can by the silicone ones in a 25 pack, but it's not much cheaper than the regular ones.

I found this:

https://www.homebrewing.org/Taprite-Co2-permanant-O-ring-for-Nipple_p_3726.html

I might just get two or three of them. A friend of mine is about to order a bunch of stuff from that site and I might just piggieback off his order.

I unscrewed that center retaining screw and I found a small gray cylindrical thing behind it. What is that for? A filter?
