National Rubber

What National Rubber does

National Rubber Corporation is a privately held custom rubber parts manufacturer founded in 1997 and headquartered in a 68,000 sq. ft. facility in Canonsburg, Pennsylvania. The company produces engineered rubber molded parts, extrusions, die-cut components, and secondary fabricated assemblies, operating five interconnected service lines: custom molding (compression, transfer, injection, and insert processes), custom extrusion, precision die-cutting, secondary fabrication, and proprietary custom compound mixing. NRC works with a broad materials portfolio including Butyl, EPDM, Fluoroelastomers, Neoprene, Nitrile, SBR, Silicone, FKM, Viton, and sponge elastomers, with compliance to FDA, ASTM, NSF, UL, and AMS standards where required.

The business serves B2B customers across automotive, aerospace, healthcare and medical, food and beverage, industrial, mining, agriculture, and appliance verticals, supplying seals, gaskets, o-rings, weather stripping, vibration dampers, diaphragms, and other custom-profiled components. Differentiated capabilities include in-house custom mixing using variable speed 50HP mixers with three downstream mills for batch-to-batch consistency, drilled front rolls with precision temperature control for heat-sensitive compounds like silicone, and die-cutting to ±0.02" tolerances on parts up to 48" by 72".

Revenue is generated through project-based, quote-priced orders with custom specifications; pricing varies by material, process, tolerance, volume, and complexity, and contracts can run multi-year. Go-to-market is sales-led and direct: customers engage NRC via the company website, phone, or email, and NRC works consultatively from design through prototype to production. The company holds ISO 9001 certification and appears to be founder/owner-operated with no disclosed institutional investors, no subsidiaries, and no identified M&A or partnership activity.
