We now custom laser cut all of our base flange gaskets.

Material is Buna-n . 60A durometer, -40-220 deg heat range, 1,500 psi tensile strength.

To maintain their size and shape under heavy compression, these gaskets have one layer of nylon fabric for every 1/16” of thickness.

.062" - .125" thick TBI and CFI base flange gaskets

.125" Holley 4150 base flange gaskets

 

If taken care of properly these should be the last gaskets you will need for your TBI
