摘要

The male connector plug has a cylindrical body portion which has a forward cylindrical section of a smaller diameter and a rear cylindrical section of a larger diameter. Each such body section is surrounded by an O-ring. The mating female connector plug has a tubular body portion whose bore defines a forward cylindrical bore section of a larger-diameter and a rear cylindrical bore section of a smaller diameter. Each bore section has an annular groove therein.
