	I have considered Viton here, both in sheet form and as O rings. 
Haven't pursued it further yet because the gaps need to be very
accurately spaced and perfectly parallel to each other.  I worry that an
elastic washer couldn't maintain both criteria.  A suitable flat
washer/spacer with an O ring seal OUTSIDE for a pressure seal would
probably work just fine.  Still need the hard spacer, but in that case
it wouldn't have to make a perfect seal.
