I have a couple of taps in my kitchen which have push-on plastic tops.
They push down onto splines on the adjuster which is about 1/4 inch
diameter.

Does anyone know of a source of plastic push on tops? I guess there
are many sizes so it may not be possible to obtain such a low cost
item.

If you're replacing the taps soon anyway then you could just be brutal
and use araldite .... just don't expect to do any further maintenance
in the future.
