    GEORGE W C  self repair
    Shopper  what is the size of the o ring?
    Wayne H  Not quite sure what to make of this question exactly...this is a -214 sized o-ring with an inside diameter of approximately 1", an outside diameter of approximately 1-1/4", and a thickness of approximately 1/8".
    Shopper  Hi there - dumb question, but is this the o-ring that goes in a regular first stage??
    LeisurePro S  This o-ring is between the tank and the tank valve. Nothing to do with a regulator.
