I was using a home made copper washer, but it needed annealing too often and most times leaked after three runs. I've just recently cut a washer out of 4mm balsa wood, soaked it in water and fixed it into position and clamped down tight. It formed itself into the same shape as the rubber ring and has been great so far. Two stripping runs and two spirit runs. The balsa plank measured 100mm x 1000mm x 4mm and cost 6 bucks.
When I purchased mine a couple of month’s back I told the guy that the seals would need to withstand Ethanol, methanol and acetone , he mentioned they can supply the seals in 3 different material (rubber, Viton and silicon) he checked his catalogs and supplied Silicon seals.
