Fibre washer for outside tap

I need a fibre washer for an outside tap but, having visited a couple of local DIY shops, can't find the right size.

Not having much luck looking online either as I'm not sure what size is required.

Anyone know the correct size?

    I’ll start the bidding at 15mm

    It is actually 1/2" but we won't go there

    Is the washer for the hose connection to the screw thread on the tap outlet? (or inside the tap body itself?)

    If its the hose connection I believe that some screw threads are the same as a washing machine outlet valve size..... 3/4" bsp I believe .

    So you probably could use 3/4" rubber or fibre washers.

    If its inside the tap body itself ...not sure ....but for the cost most people would change the tap anyway

    Maybe this would be useful

    An old inner tube or similar rubber cut to size with a hole pushed through it should do the job of it is not constantly being removed. You are only filling in the rough areas between 2 mating surfaces. At a pinch you could use a modified balloon as a temporary one off

    PTFE tape around thread as you screw on the brass tap to the wall mount with the 15mm water pipe connected.

    Not sure where you are putting the fibre washer?

    Thanks for the replies.

    The tap already has PTFE tape on it but, once tightened, is horizontal.

    Someone suggested solving by using a fibre washer.
