Precision cut gasket using Flexoid British made gasket paper. I have designed this myself for perfect fitment to the standard inlet manifold/thermostat housing joint on the V6 Essex Engine. 1.5mm thick to allow for any slight tolerance issues.

Note: Please ensure the base of your thermostat housing is free from too much corrosion, this is common. If you have this issue you can carefully flatten the base using a sheet of metal under some 120 grit emery paper to sand it flat with water.
