Ok, purchasing check valves from mcmaster. The above is an option when choosing an 1/8" nylon check valve w/ barbed adaptors. I'm not sure of the difference. I found this, but that was in refference to o-rings. Can anyone offer some help?

Hey...I got a crazy idea: how about you stop all that sigging stuff? It's not even my thread and it annoys me.

Get either, it doesn't really matter. Assuming you're using the check valves to check air for Nerf purposes, of course. If you're shooting chemicals through for whatever reason, you might want to delve deeper into the properties of the two types. For air, they'll both be perfectly fine. Get the cheaper one.

I got the Viton one (or whichever one had chemical resistance) just in case silicone spray got into it from getting a tank to seal.

The check valves have an o-ring in them that forms the seat for the ball bearing. (I'm assuming here that you're buying the standard check valve which is the spring-loaded ones).
So uh, reread Slug's post.

Whoops...misread. Still important though, cause I'd like to know which of the two would be more chemically resistant. While Buna N is mentioned, Fluorelastomer is not.

Viton is a brand of fluoroelastomer.
