Slip joints help seal leaks in sinks. They have plastic or metal slip nuts that have a washer beneath them. When the slip nut is tightened the washer is compressed hence forming a seal that prevents leakage.
How to Install Slip Joint Washers in Plumbing?

For sink basket strainers tailpiece, make sure that you first slide another slip nut on and that the threads are facing the tail-pieces self-seating end.
- The third step is sliding the slip joint washer onto the pipe. Make sure that the thicker edge of the slip joint washer faces the slip nut and that the washer fits snugly against the pipe. To allow the pipe room to slide into the threaded fitting, ensure that you slide the washer approximately 2 inches away from the edge of the pipe.
- The fourth step is tightening the slip joint. To tighten the slip joint, do the following:
- Ensure that the pipe slips into the flared fitting by slipping it into the threaded fitting.
- If you notice that the fitting is not flared, continue pushing the pipe until the washer is in the threaded fitting.
- Now press the slip joint washer down until the tapered end snug against the thread fitting and fits in straight.
- Finally slide the slip joint nut over the slip joint washer and tighten it using your hand until it’s snugs onto the threads.
