Robb Nortier from this site had made some leather washers that I was selling on his behalf. I'm out of stock, but you could ask him. Ron

I made a leather one out of an old brief case. Mine is not a 100% seal.

Hello All,

Robb did used to have the leather gasket, but he is currently out of stock,
And for my understanding he put the business away for a while do to relocating.
I do use some of his tolls and are all just great!

I needed some material for my fuel and oil tank,
And ordered some Nitrile Rubber gasket material for Fuel Oil,
Cut it by myself, and it works great !

I did like Noam did, ordered a sheet of that rubber (inexpensive) and cut my own gasket. Works perfectly.

Good luck!

Thanks for the opinions. I'll try both the leather & nitrile rubber. But perhaps the Kwaka gasket on now's nitrile too?
