I'm the lucky 
owner of a lovely Worcester Greenstar 28i Junior MK3. I have a few non gas jobs to do to it which will involve me undoing the unions for flow and return and maybe cold in and hot out unions where the boiler meets the jig. It's the washers that sit on the top of the isolation valves.
It would be a good idea to put new washers in these unions while they are apart. I'm assuming they're fibre. Can I buy a pack with all the union washers? If yes, where from? Or should I buy them individually - and if yes, what size are they?
Many thanks for any advice.
