A quick connect and disconnect pipe coupling and seal assembly including a first generally cylindrical coupling head having a bore therein for connection to a first conduit and a raised annular ring, a second generally cylindrical coupling head having a bore therein for connection to a second conduit, external male threads, and an annular recess for receiving an O-ring, and a generally cylindrical coupling ring for holding the first coupling head therein, the coupling ring having a threaded bore for receipt of the external male threads of the second coupling head to connect the first coupling head to the second coupling head and to force the O-ring received in the annular recess of the second coupling head into contact with the annular ring on the first coupling head to form a high pressure seal between the first coupling head and the second coupling head.

What is claimed is: 1. 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
What is claimed is: 1. 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. 2. The coupling assembly of claim 1 wherein said first conduit is a pipe having external threads thereon. 3. The coupling assembly of claim 1 wherein said second conduit is a pipe having external threads thereon. 4. The coupling assembly of claim 1 wherein said first coupling head has a groove therein for receipt of a snap ring for connecting said second coupling to said coupling ring. 5. A quick connect and disconnect stationary pipe coupling assembly comprising: a. a first generally cylindrical coupling head having a threaded bore therein for connection to a first threaded conduit and a raised annular ring extending around one end of said bore, 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, b. a second generally cylindrical coupling head having a bore therein for connection to a second threaded conduit, external male threads, and an annular recess extending around one end of said bore for receiving an O-ring, said annular recess having an end face with a groove therein and 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, 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. 6. A seal assembly for a stationary pipe coupling comprising: a. a first coupling member having a bore therein for connection to a first conduit and a raised annular ring extending around one end of said bore, said raised annular ring having a curved outer edge, said curved outer edge of said raised annular ring having a groove therein, said raised annular ring having parallel sidewalls, b. a second coupling member having a bore therein for connection to a second conduit and an annular recess extending around one end of said bore for receiving an O-ring, said annular recess having an end face and said end face having 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, and c. a third coupling member for connecting said first coupling member to said second coupling member.
