General   (General discussion, talk about anything.)

Yes, Tom, I know. But it's not that 'washer'that's required (I think). It's a 'seal'.

It's this one ....




The 'shaft' (moulding) will be 20mm dia., then the seal might be anything mm, then the outside dia. will be the same as the plug.

P.S. I've got a couple in the garage, but they're both bigger than 20mm shaft dia..

P.P.S. I thought a flat o-ring might do, but maybe not, as it'd have to fit in the slot in the moulding. They'll be bastardised.

P.P.P.S. I could be wrong, After all, I'm not a real welder!
