Dike-O-Seal Preform Seals




Dike-O-Seal Preform Seals provide an effective seal in foundry core boxes and gassing plates.

Dike-O-Seal can be installed and secured without use of an adhesive in most cases. Corners can be machined at 45┬░ to the intersecting grooves and this will allow the Dike-O-Seal Preform Seal to be set in the groove without cutting and bonding ends together. Available in two hardnesses of 20 and 40 shore A.

Freeman F-Bond Adhesives are designed for bonding Dike-O-Seal preform seals into core box channels. These are very fast setting cyanoacrylate adhesives which allow the core box to be quickly put into production.

This material is ordered by the full strip.
