Silicone Vacuum Seal for Silicone/Rubber Molds

silicone vacuum sealvacuum seal installationM.R. Mold & Engineering offers silicone vacuum seals in two sizes for parting line sealing of silicone and rubber molds. This seal is designed with unique features which provide a tightly sealed mold.

Silicone is a material specifically formulated for the high temperatures required in the manufacture of durable silicone and rubber molds. Our vacuum seals are designed with a tapered body to prevent pinching in the parting line. This design also eliminates the compression set which can occur when using traditional O-rings. The hollow body design readily flexes to seal groove contour and the locking "feet" retains its shape in the seal groove.

This seal is sold in increments of 50 feet.
