Trying to source 28mm washer

[Crossfingers]

Hi

Im about to replace pump isolator valves on my grant boiler but the 28mm valves did not come with washers and I can seem to find them to buy. Can anyone please advise where I might be able to find them?

Thanks

Have you tried searching for a heating pump washer?

I did, maybe I'm getting confused over the size of the washers that are mainly stated in inches. I assume 28mm is the inner diameter of the washer? Would the following work?

That's the correct washer but the rubber version is much better.
Readily available any decent plumbers merchant.
If your grant boiler is a combi be very careful not to spill water it drips onto board and there easily killed!

I wemt down there earlier and bought the same. Different make but same description. I thought the rubber looked wide but I'm probably wrong
