R D Rubber Technology Corporation

What R D Rubber Technology Corporation does

R D Rubber Technology Corporation is a privately held, US-based custom manufacturer of precision molded rubber components, founded in 1986 and operating from a single facility in Santa Fe Springs, California. The company designs, develops, and produces elastomeric parts using thermoset rubber molding processes including compression, transfer, injection, and liquid silicone rubber (LSR/LIM) molding, with specialized capabilities in rubber-to-metal bonding, silicone-to-plastic bonding, insert molding, and overmolding. It maintains an on-site ISO 14644 Class 8 cleanroom and supports secondary operations such as cryogenic deflashing and conventional machining, with dimensional inspection capability ranging from 0.0003 to 14.000 inches. RD Rubber holds AS9100:2016, ISO 9001:2015, ITAR registration, NIST 800-171 compliance, DOD Joint Certification Program registration, MIL-I-45208A, ANSI Z540-1, ISO 10012-1, ISO 3601-3, and GMP certifications, and works with a broad elastomer materials portfolio that includes Viton, silicone, EPDM, nitrile, butyl, and chlorobutyl rubber.

The company serves enterprise and government customers in aerospace, defense, military, space, medical device, pharmaceutical, biopharmaceutical, food and dairy processing, semiconductor, and marine end markets, with named customers including the Department of Energy since founding and an unspecified set of aerospace OEMs. Revenue is generated on a project-by-project basis through a Request for Quote (RFQ) process, with prices determined by part specifications, material requirements, tooling complexity, and production volume, and with all manufacturing performed domestically in California. The go-to-market motion is sales-led, relationship-based, and centered on direct engineering engagement from prototype through full-scale production, supported by content marketing through the company website, technical blog, and educational eBooks targeted at engineering and procurement audiences. The product portfolio spans O-rings, seals, gaskets, grommets, diaphragms, valves, poppet assemblies, latches, and fabric-reinforced composite seals used as critical-to-function components in fuel systems, hydraulic systems, propulsion, UAVs, satellites, and high-purity processing environments.
