A fitting for a whirlpool joins a pair of pipes. The fitting includes a coupling from which one of the pipes extends, the coupling having a flexible member adapted to cause a seal to sealingly engage the pipes or the pipes to seal against themselves, and a first thread. A nut engages the coupling and has a second thread for engaging the first thread and a surface for engaging the flexible member and causing the seal to sealingly engage the pipes or the pipes to sealingly engage themselves while the second thread engages the first thread. The first thread and the second thread have an angle whereby the flexible member causes the seal to sealingly engage the first and second pipes or the pipes to sealingly engage themselves in a quarter turn of the nut.

The fitting of claim 1 further comprising; a tab disposed on one of the nut or the fitting,a lock disposed on the other of the nut or the coupling said lock extending from the other of the nut or the to the one of the nut or the coupling such that upon making a quarter turn of the nut, the lock engages the tab and prevents the nut from backing away from the coupling. 4. The fitting of claim 3 wherein the lock is a camming surface over which said tab travels. 5. The fitting of claim 1 wherein said fitting gives a visual signal that the fitting creates a seal. 6. The fitting of claim 1 wherein said fitting gives an aural signal that the fitting creates a seal. 7. A fitting for a whirlpool, said fitting comprising: a first pipe for carrying water,a second pipe for carrying water,a seal extending over a length of said first pipe and a length of said second pipe,a coupling from which one of said pipes extends, said coupling having a flexible member that compresses said seal to sealingly engagesaid first pipe and said second pipe, anda first thread,a nut, said nut having, a second thread for engaging said first thread anda surface for engaging said flexible member and causing said flexible member to sealingly engage said seal and seal said first and second pipes while said second thread engages said first threadwherein said first thread and said second thread have an angle whereby said surface causes said flexible member to sealingly engage said first and second pipes in a quarter turn of said nut. 8. The fitting of claim 7 further comprising; a tab disposed on one of the nut or the fitting,a lock disposed on the other of the nut or the fitting said lock extending from the other of the nut or the fitting to the one of the nut or the fitting such that upon making a quarter turn of the nut, the lock engages the tab and prevents the nut from backing away from the quarter turn. 9. A fitting for sealing two pipes, said fitting comprising: a seal extending over a length of both of said pipes each of said pipes carrying a fluid,a coupling from which one of said pipes is adapted to extend, said coupling having a flexible member adapted to cause said seal to sealingly engage said pipes, anda first thread,a nut, said nut having, a second thread for engaging said first thread anda surface for engaging said flexible member and causing said flexible member to sealingly engage said first and second pipes while said second thread engages said first threadwherein said first thread and said second thread have an angle whereby said flexible member causes said seal to sealingly engage said first and second pipes in less than a full turn of said nut. 10. The fitting of claim 9 further comprising; a cam surface disposed on one of the nut or the fittinga lock disposed on the other of the nut or the fitting said lock extending from the other of the nut or the fitting to the one of the nut or the fitting such that upon making a quarter turn of the nut, the lock slides over the cam surface and prevents the nut from backing away from the quarter turn.
