The Industrial/Milton Design has been adopted by most coupler manufacturers, including Milton, Hansen, ARO, Lincoln and Schrader. This plug design is considered the industrial standard. It will work with either "sleeve" type or "push" type couplers. No matter what the coupler looks like, if it mates with this plug, it is an "Industrial/Milton Interchange" design. It can be identified by the 3/16" pilot and flat bottom V-shaped ball groove. Conforms to ANSI (NFPA) T3.20.14-1990 dimensions.
