Patent ID: 6994380

Claim:
A quick connect and disconnect stationary pipe coupling assembly comprising: a. a first generally cylindrical coupling head having a bore therein for connection to a first conduit having external threads thereon, said first coupling head having a raised annular ring extending around one end of said bore, said bore in said first coupling head having female threads therein for connecting a threaded conduit thereto, said raised annular ring having a curved semi-circular outer edge, said curved semi-circular outer edge of said raised annular ring having a groove therein, said raised annular ring having parallel sidewalls, said first coupling head having an annular shoulder extending around said coupling head adjacent to said annular ring, b. a second generally cylindrical coupling head having a bore therein for connection to a second conduit, external male threads, and an annular recess extending around one end of said bore for receiving an O-ring and said raised annular ring, said annular recess having an end face with a groove therein, said annular recess having two parallel sidewalls extending perpendicularly from said end face, said two parallel sidewalls of said annular recess having a distance therebetween greater than the distance between said parallel sidewalls of said raised annular ring of said first coupling head to prevent said two parallel sidewalls of said annular recess from contacting said parallel sidewalls of said raised annular ring of said first coupling head, said bore in said second coupling head having female threads therein for connecting a threaded conduit thereto, and c. a generally cylindrical coupling ring for holding said first coupling head therein, said coupling ring having a threaded bore for receipt of said external male threads of said second coupling head to connect said first coupling head to said second coupling head and to force said O-ring received in said annular recess of said second coupling head into contact with said annular ring on said first coupling head to form a high pressure seal between the first coupling head and said second coupling head, said coupling ring having handles extending from the exterior thereof for connecting and disconnecting said first coupling head from said second coupling head.
