Hello all,
I'm not a rubber or seal expert - my experience with these are quite elementary. I apologize in advance for any really dumb questions.
My company is Reverse Engineering a Back up Seal for an aircraft application. The material appears to be a green viton by virtue of the packaging that states the material is "Fluorocarbon FR 44/60" manufactured by James Walker & Co. The Seal is reportedly made in Japan or Europe.
Is anyone familiar with this type of material, and what is the governing spec? Is this a French National Spec and is there an equivalent American material spec (MIL-R-83248, AMS 3216, etc.)?
Also, the configuration of the seal is quite odd. I've seen Quad-Seal Back Up Seals, but this seal has two lobes of different sizes (.060R & .025R) at the two opposite corners of an equivalent Quad-Seal. Is this a common configuration for a Back-Up Seal?
Thanks in advance for any help you can provide,
Chris Marinelli
