Yong heng orings?

[CorbettH]

I recently overlooked my Yong Heng compressor and the green oring that operates the check valve was warn but working. This is the one that is just below the burst disc. I looked through the set that came with the unit and that particular one was not included. I see you can order out of China a new set but I am concerned it might be like mine. Has anyone had this problem or resolved it by obtaining the individual correct oring? Up to 3 air gun and hardly touch my centerfires.

I've never had any of those fail. And pretty sure came with them, too.

I updated my post as I am still learning and didn't realize that there were more than one.

I would have to remove the fitting just under the bust disc to show you. It's rather small and operates with a spring

Happened to me last summer and replaced with black Buna 90, couple hours on it so far.
A reason to destroy that oring is a human error. When you bleeding the first=oil separator open it slow otherwise you pulling that spring torpedo back...

That makes sense! I am now bleeding off my new moisture separator. Where do I find this magic o ring?
