Detroit Sealing Components (DSC) is a stocking warehouse and distributor rooted in decades of experience in the precision molded rubber industry. Headquartered in Plymouth, Michigan—a hub for advanced manufacturing and engineering—DSC's skilled leadership and technical staff have built a reputation for delivering innovative, robust, and cost-effective sealing solutions nationwide. Our team's deep knowledge of NSF 61 and drinking water compliance standards means customers receive not just a product, but a fully vetted, application-specific solution. Whether supporting a municipal water authority replacing aging gaskets or an OEM specifying O-rings for a new water treatment system, DSC's experts bring the materials science, testing capability, and supply chain speed to get compliant seals where they're needed, when they're needed.
Common NSF 61 certified elastomers include EPDM (Ethylene Propylene Diene Monomer), silicone (VMQ), and select grades of FKM (Viton). These materials are evaluated for extractables that could migrate into drinking water. The specific compound formulation—not just the base polymer—must pass NSF 61 testing, so certification is compound-specific.
