Anyone running one of these? My New S476 was sent without this o-ring. Seller claims that below 40 psi they really aren't needed? Also said they would be happy to send me the o-ring if I wanted to run it.

I don't recall an o-ring being on my Cast S475 either now that I think about it. I'd assume it's there for a reason and I should run one.

How are all of yours setup?
