Tap washer
 

I needed to change the basin tap washer. I got a half inch washer out of
an old pack, but I was surprised to find that it doesn't fit. The tap
head has a sort of cup the washer fits into, and the washer is a bit too
big.

I'm pretty sure it's this one:

I suppose the correct washer size might be 3/8"? But then why is it
marketed as 1/2"? And in any case, I don't think the difference is as
much as 25%.

Is it a "cup" with a dimple in the middle? If so you might be in need
of a Barking Grohe Washer which is rounded at the bottom. Eg

If so I've sometimes bodgered an ordinary one by shaving the bottom edge
so it fits into the cup. But then I've also met old taps where I had to
shave what purported to be a BG washer because the "cup" was
distorted/corroded. Or it might of course have just been me who was ;)

There's no dimple. The cup is just smaller than the washer!

I turned the old washer over, and reassembled it. Otherwise, I'd take a
photo.
