The cylindrical canister includes a port for connection to a deep vacuum source and the cover includes a port that is for connection to a low level vacuum source, with the deep vacuum to remove air from the elastomeric material mixture as it is poured into the canister, and with, after filling, the port is open to atmosphere and the needle valve is opened to exhaust the mixture into the mold annular chamber wherethrough it is pulled by the low level vacuum through the cover port, filling the mold annular cavity and thoroughly impregnating the core maintained therein.
