Text excerpt from the catalog:
These James gaskets are made out of SAE 1010 mild steel that will not crack, tear, rip or creep out during assembly and gives excellent torque retention. The steel base is bonded on both sides with "Anti-Wick" oil resistant silicone rubber coating to micro-seal the aluminum castings and have an additional release coating to facilitate removal of the gaskets upon disassembly. Cylinder base gaskets feature silicone beading around the inside bore and outer perimeter on each face, seal at elevated temperatures and retain maximum torque, will not become brittle and burn out like paper gaskets and will not split or extrude out during assembly. The excellent sealing properties and extended service life of these gaskets make them ideal for both stock and High Performance applications.
