TL;DR
A slip joint washer is the tapered or flat sealing ring, in rubber, nylon, or polyethylene, that seats inside a slip nut to seal the tubular drain connections under sinks and tubs. The beveled face points toward the threaded fitting so tightening the nut compresses it around the tailpiece or trap arm.
What it means
A slip joint washer is the tapered or flat sealing ring, in rubber, nylon, or polyethylene, that seats inside a slip nut to seal the tubular drain connections under sinks and tubs. The beveled face points toward the threaded fitting so tightening the nut compresses it around the tailpiece or trap arm. It is the part most often at fault when a P-trap drips after being disturbed, and replacements cost cents, which makes it the first thing a plumber swaps.
