National Rubber Corporation is a U.S. manufacturer of custom rubber components, sealing solutions, and engineered elastomer products. We combine extrusion, molding, die cutting, and secondary fabrication under one roof to deliver consistent quality and tight tolerances. Our team supports projects from design-for-manufacture through repeat production, serving demanding applications across aerospace, automotive, appliance, electronics, transportation, construction, chemical processing, healthcare, and food & dairy. Materials include EPDM, Nitrile (NBR), Neoprene, Silicone (including FDA and high-temp grades), Fluoroelastomers, and specialty compounds matched to environmental, thermal, and regulatory requirements.

We help engineers reduce leakage, vibration, and noise; improve weather resistance; and enhance safety and longevity of assemblies. Typical deliverables include U- and C-channels, edge trim, grommets, O-rings and cord, sponge profiles, bumper stops, and precision die-cut gaskets.

Our process begins with application discovery and material selection, weighing tradeoffs in compression set, media compatibility, temperature range, abrasion, and cost. We then review profile geometry for manufacturability and consistent sealing force, produce rapid samples where needed, and finalize tooling for repeatable production. Incoming materials and finished goods are inspected against documented specs with lot traceability.

For OEM programs, we align on inspection plans, PPAP documentation, packaging, labeling, and replenishment strategies. Our in-house secondary operations cut lead time and reduce handling, while our team coordinates testing for specialized certifications or customer-specific standards. The result is a dependable supply of components that fit, seal, and last.
