"Hoses Direct" sell fibre washers in imperial sizes, when I see you Hugh I can probably produce a sample or two (I need to remind myself whether they are narrow or not).
You wouldn't want to order just one though, I order a few when I'm buying something else. (If stuck for something specific, give me a shout).
I usually boil them in water for a minute or two before using them, softens them up a bit.
