Paintball Cylinder Threaded Port Dimensions

  1. Oct 8, 2007 #1
    Does anybody have information on the threaded cylinder port that a paintball pin valve threads into?

    I know it's a 5/8-18UNF-2B thread, but I need to know the dimensions for the o-ring surface of the port.

    Any pressure cylinder should have a DOT number on the side. Can you find out what it is?

    I take it the o-ring is a face seal?
