Supercharger Plenum Rubber Seals
Supercharger Plenum Rubber Seals
(OP)
What type of rubber should be used to seal the plenum of a supercharger to the cores of an intercooler. Silicone comes to mind first, but would EPDM (peroxide cured) also work.





RE: Supercharger Plenum Rubber Seals
If you are just sealing the hot air from the supercharger, then silicone may be your best bet (although EPDM would work to 300 F or so). But use an O-ring or similar, don't count on any strength from silicone rubber.
For sealing on the fluid side (water, glycol mix) use EPDM.
