Plastic ballvalves do contain fibre washers or do they sell a different types in England?
Not going round in circles with this but you are wrong wrong wrong and I don't care how long you've been in the trade.
No offense mate but we are either talking about something completely different from each other or one of us is talking nonsense and it ain't me

We are talking about tap connectors not the insides, so don't change the subject, or edit your post
The tap connector to plastic ballvalve does not need a washer.
If as you say you are going round repairing hundreds of failed fibre washers then you must live in Cowboy country.
Be honest, how many tap connectors that you have fitted have you had to go back to because the washer has failed. Not a lot if any I bet.
