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. |
