This gasket is one tough one to cut out by hand, so we had a bunch made. This is the washer located inside the nut that’s floating on the Water connector under the sink. This only fits American Standard faucets, but if you are creative, it can be modified to fit other brands. The washer measures 1 1/16″ OD, and mounts on pins 5/8″ apart on center. Sold by the each! Pictured yoke shown as example of washer location only. Yoke itself not available. Note, this washer will not work on single hole sink faucets where the pop-up rod goes through the faucet.
