I hope this is the right SE site to ask this. The sprayer on my kitchen faucet has started to leak. I bought the faucet and sprayer as a combo (brand new) about two years ago. It's a unit where water is not supplied to the sprayer hose unless the faucet is on. Now, when I do turn it on, water leaks from the area where the sprayer hose enters the sprayer handle--not from the sprayer head.
So, I unscrewed the sprayer head from the hose connection, and I think the problem is this washer (or gasket) on the end of the hose. I can't find this part anywhere, and it's a tough one to google for. Hopefully, the picture will post. The washer has two concentric raised rings: one is the outside diameter, which is about 0.75". The other is at about 0.5" diameter. The whole washer is about 0.125" thick (in the direction toward you in the picture).
So, I have to find one of these mystery washers/gaskets, or spend $25 on a new sprayer. Can anyone tell me what they're called? (I've looked at the home improvement stores, and more than an hour googling and looking through ALL of Amazon.)
