OEM & MRO Gaskets
Style 1301 - Vulcanized Custom Gaskets
Large gaskets can be die cut segmented, then vulcanized into a one piece construction utilizing a matching polymer and a heat/pressure curing process (elastomeric material only).
We carry a wide range of materials, so if you don't find your material in the list, please call us @ 1-800-876-SEAL, or
