Since 1977, R&R Rubber has been a family-owned American manufacturer specializing in precision-molded rubber and elastomer components. From aerospace and defense to oil & gas, food & beverage, water infrastructure, and industrial equipment, our parts are engineered for industries where failure is not an option.
Founded in 1977, R&R Rubber Molding, Inc. began as a small custom molding shop committed to making the kinds of parts others couldn’t. Over the decades, we expanded into bonded and overmolded assemblies, reinforced components, and compliance-driven solutions for aerospace, defense, and critical infrastructure.
What has never changed is our independence. As a multi-generation, family-owned company, we take pride in American manufacturing while serving customers worldwide. That mix of heritage and adaptability has made us a trusted partner for over four decades.
Our mission is clear: make it right, make it custom, and make it perform.
We don’t just mold parts — we deliver solutions. Whether it’s an AS9100-certified bonded isolator for aerospace, a NORSOK-compliant seal for oil & gas, or an FDA-grade diaphragm for food processing, we support engineers and buyers with components that meet strict compliance standards and excel in the field.
Every part is an opportunity to engineer confidence into your system.
Our vision is to be recognized as the most trusted and versatile custom rubber molding partner in the U.S. — and beyond.
We aim to combine the precision and accountability of American manufacturing with the reach and responsiveness of a global supplier. By leading with technical expertise, compliance, and lasting relationships, we continue to grow through partnerships built on trust, performance, and shared success.
