The best course of action is often to order o-rings of unknown size, or o-ring spec number, direct from Crosman.   Most o-rings are $1.15 each.   Find the Crosman part number of all the o-rings in the EVP, order same, and measure for future local purchase, or from o-ring vendor.   Shipping is flat rate at $4.00 except for barrels.

I think they are:
003 = .177 bolt
005 = .22 bolt
012 = between valve halves
111 = outside of valve

Some of them are 1 cent a piece at the oring store.

I did some measuring and I am unsure of the size for the bolt orings.
Possibly metric. I ordered several different sizes that might fit improved tighter versus original.
Anyways , I don’t have the answer yet.
