Trying to soiurce a 3/8 curved shoulder tap washer

[Ageingsurveyor]

I'm trying to find a new washer for the cold tap in the bathroom handbasin in my fathers bungalow - built in the 80s. Its 3/8 inch in diameter with a curved shoulder. I can find similar shaped washers but only 1/2 inch or 3/4 inch. I'm attaching a picture of the washer and of the tap in case that helps.

Grateful for any assistance - thanks.

How about trying a flat washer to see if it works

Dose it say 3/8th on the washer or have you measured it?

I've measured it and compared with a flat 3/8th washer

Thanks for suggestion but the central hole is much bigger than a standard flat 3/8.

Try a 1/2inch washer they wear down after a couple of years

 

[Ageingsurveyor]

Thanks but I've tried that and the tap is immoveable

I reckon a 1/2'' will be fine, they may not actually be 1/2'', they could be called that because they fit into 1/2'' taps (basin/sink taps) and not 3/4'' taps (bath taps).
Have you tried one?
Never measured one to be honest though, don't come across domed washers often but when I have the standard ones in tap repair kits have always worked fine. The tap in your picture looks like a standard budget tap, which I've worked on many times, if a 1/2'' washer doesn't work I'd replace the taps for the price of them.

You get these type of washers in the box sets that you can buy, around £7. or go to the DIY outlets
