(33 products)
Curated rubber washers for faucets, supply lines, slip-joint drains, garden hose fittings and fixture sealing — the sizes plumbers reach for most, each available in EPDM, Neoprene, Nitrile, Silicone, Natural Rubber, Viton and Fiber. For potable water and hot/cold cycling, EPDM is the go-to; Neoprene handles general fixture duty.
