Garden Hose to 5/8 UNF Adapter

This adapter connects normal North Americal male garden-hose style threads to a weird 5/8" UNF 18TPI thread socket. An 11/16" o-ring will fit snugly in the socket.

My boss' pressure washer, a Simoniz model, is plugged or seized in an area which can't be opened and cleaned. With this adapter, I hope to plug a garden hose into the **outlet** of the pressure washer, to force the clog back out of the partially disassembled valve. Wish me luck.
