Rubber Cone Washer

This is a replacement cone washer used when attaching a compression-fitting style water connection to a faucet.

We offer these in three sizes to fit your standard shower part connection sizes. (Choose your option below)

Our Large size (7/8" Outside Diameter, 9/16" Inside Diameter) is meant to connect your 5/8" OD (outside diameter) shower riser tube to your faucet diverter connection. If your shower riser attaches to your faucet diverter connection using a 3/4" IPS compression nut, this would be the washer you need.

Our Medium size (7/8" Outside Diameter, and 1/2" Inside Diameter) is meant for a 3/4" IPS threaded connection to your Hot and Cold supply lines at the faucet. These are typically for a "tub wall mount" faucet that attaches to the interior vertical tub wall. If you have 3/4" IPS compression nuts connecting your supply lines to your faucet inlets or shutoff valves, these are the ones you want.

Our Small size (23/32" Outside Diameter, and 1/2" Inside Diameter) is for use with a 1/2" IPS threaded nut for connecting your 1/4" O.D. Hot & Cold water supply lines to your faucet inlets, or shutoff valves. Typically, this size would be used to connect your water supply lines to a bathtub rim mount faucet (a.k.a. "deck mount" faucet), or to a set of water supply shutoff valves that use 1/2" IPS nuts. If you have 1/2" IPS compression nuts connecting your supply lines or shutoff valves, these are the ones you want.

All of these cone washers list above are used with special connection nuts in a compression fitting connection. (Called either a "Riser Nut", "Compression Nut", or a "Supply Line Nut")

Pricing is per washer, Free Shipping included.
