Seal Science say they have it all: http://www.sealscience.com/html/products/VacuumCupsPdfs/15about.pdf
ultrahighvacuum guys use pure gold gaskets: http://www.sisweb.com/catalog/F39.pdf
ourselves, we use as simple as butyl rubber: http://www.allstategasket.com/materials.asp (not Ultravacuum, of course)
Butyl rubber group includes ordinary rubber used in your mountainbike tire, can keep vacuum or pressure for very long time.

i believe you should be able to use a gasket material such as viton.

Subject: [TN] thin film
Good day all,
I am in need of a recommendation for a thin film sealant material. I need
it to be 15-20 mils thick, cuttable, and preferrably non silicone. We have
considered the Sil-Pad technology, but as this will be used in a vacuum
seal operation, I am concerned about silicone outgassing or cross
contamination. Are there any thin gasket materials from the engineered
rubbers that anyone would recommend?
