Decorating caps. Or a float valve washer over the pin.

Or a half inch brass cap with a fibre washer inside it

you can also put such a cap on the end of the valve where the big nut on the radiator tail normally screws on.

Stops dripping valves.

i have wound a flexible tap connector with an isolator on it so that when you come back to put the rad back on you can drain off the excess

works well that does
