We have several of these Lowes Aqua Source fill valves (in our office), original from when the Aqua Source toilets were put in around 2006 or so. Needless to say, the gaskets have become shriveled up over time. The actual fill valve gasket, the bellows shaped thing that actually shuts the water off seems to still be in working order. But the thin, flat, round gasket under the fill valve assembly is the part that is shriveled up and causes the fill water to kind of spray all over instead of properly directing it to the tank and bowl. I have done some searching and found no mention of any replacement. Looking for both a cheap way to fix these (maintenance budget is near zero) and also it seems stupid to toss all this plastic when a simple rubber gasket could do.


Here's what a typical gasket looks, like, all shriveled up and barely doing anything:


it should fit flat in here:

The gaskets that are in there are just too damaged to even try to measure. Any ideas on where to get flat gaskets as replacements or what the measurements might be so I can take a stab at getting them locally?
I know fill valves aren't that expensive but if I have to replace all of them to get the toilet to fill properly that will be some real money. Even if the replacement gaskets were a dollar each that would still be a savings.
Thanks
