Got used co2 and reg, something is wrong
1 Attachment(s)

Okay, I got a used co2 cylinder with a regulator. When I open the valve (and plug hose using my thumb) i notice a leak on bottom side of regulator where there is a SS washer under a brass adapter. There is an o-ring on the brass adapter (regulator side). The SS washer is just big enough to rest on the O.D. of the o-ring. Is the o-ring bad or is this SS washer setup even supposed to be there?

Here is a pic of brass adapter with SS washer in place:

Here is a pic of the brass piece removed from body of reg. notice the o-ring on the end heading to regulator body. The o-ring and washer just don't look right to me...
