Does anybody know where i can get hold of some Copper 'Crush' Washers ?

I need some 1/2" Bsp ones for a dry sump system

Have tried the bay of 'E' and done a google


Thanks

Any of THESE any good?

Dowty Seals are a good alternative

We use them at work, if you u2u me tomorrow I will confirm the size we use.
