Please can anyone tell me where I can get some new rings that seal the caged valve assemblies to the head/cylinder on early lister A's (1924) ?
They are a tad over 1.5 inch I.D. (actually 1.6 or about 41mm ?) and are composite copper/asbestos? and about 3/16 inch thick.
cheers,
Phil
Hi Phil
I've yet to come across anyone who can supply rings to this size made from composite copper/asbestos. I can only suggest contacting Brian Harfield who can manufacture them in copper. He advertises in Stationary Engine magazine.

Thanks for that John,
One error I've just noticed, they are nearer 3/32 inch thick not 3/16 as I stated,

Phil,
I got around it by making a pair of rings from a suitable thickness gasket material and smearing silicone sealer on both sides before fitting and many years later they still dont leak.
