15mm Screw Coupler & Plug Adapters - 3/8" FPT

The 15mm screw connection is the smaller cousin of the common 22mm screw fitting, found on lighter European-style guns, lances and hoses. These adapters take that 15mm connection and give you a standard 3/8" female pipe thread so you can attach normal fittings.

The coupler is the female half - it threads onto a 15mm male screw end. The plug is the male half - it threads into a 15mm coupler.
