The title may not explain what I am having an issue with as I am not really sure what the gasket is called. My hope was that someone might know what it is and/or know what I it is calle, which would help me in my search for a replacement.
Anyway, where the shower hose connects to the faucet at the blend tube, there is a small black rubber gasket that kind of looks like a top hat. The gasket seems to have stiffened and no longer seals water from escaping when under pressure. At first I thought that there might be debris keeping it from sealing but even after cleaning it still leaks.
For additional help I have added a few pictures of the gasket still in the faucet output connection point, the faucet connection point with gasket removed and pictures of the gasket itself.
Any help would be appreciated.
