GraphTite™ (suffix of “G”) – MBG is a high performance gasket material combining expanded graphite facings on 0.2mm (0.008″) tang perforated tin-plated steel core. It is ideally suited for internal combustion engine applications such as head gaskets. MBG is compressible and resilient, yet offers excellent bolt torque retention, excellent chemical resistance, and is heat resistant for exhaust gas sealing applications up to 550°C (1000°F) or higher when shielded.

GraphTite™ head gaskets have superb sealing characteristics and hold up to the punishment dished out by high-performance engines – high quality all the way. This gasket might be overkill for cruiser engines, but so what . . extra performance never hurts!

Install GraphTite™ head gaskets using using a spray-on sealant like K & W Copper Coat or Permatex Copper Spray-A-Gasket. Always re-torque, no short-cuts.

With steel fire rings

Does not work in pre-64 389-421 if oiling through rocker studs
