Engineered for Quality Performance in Military, Aerospace, Propulsion Systems, Medical Technology & Food Processing.
In mission-critical environments, the integrity of a single seal can determine the success of an entire system. At RD Rubber Technology Corporation, we specialize in precision custom rubber molding of elastomeric components for critical-to-function applications. From undersea to high altitude and into space, our components are engineered to provide reliability under extreme thermal, chemical, and mechanical stress.
As an ISO 9001:2015 and AS9100D certified manufacturer, RD Rubber ensures that every component—from custom-molded rubber O-rings to rubber-to-metal bonded components—meets the rigorous quality and traceability standards of the Defense and Aerospace sectors. We also manufacture custom rubber components for other regulated industries such as MedTech and food processing which also undergo rigorous quality testing.

Benefits of Using Custom Rubber Products
Custom molded rubber parts and fabric-reinforced rubber products provide numerous advantages in a wide variety of applications.
Durability
Custom-engineered rubber products are a reliable choice for a wide range of applications due to their overall resilience in harsh environments and extreme temperatures ranging from -148° F to 590° F. By integrating advanced fabric reinforcements, such as Nomex, custom rubber components achieve even greater thermal thresholds – exceeding temperatures of 800° F before carbonizing. This composite construction allows rubber to outperform homogeneous materials in durability and sealing performance, as well as maintain structural integrity and dimensional stability even under prolonged periods of high pressure.
The durability of reinforcing fabrics is a critical factor in extending the operational lifecycle of molded rubber seals and parts. Nomex, a flame-resistant meta-aramid, provides a barrier that does not melt or drip, nor supports combustion which makes it indispensable for high-risk industrial and aerospace applications. When blended with Kevlar, it gains significantly improved tensile strength and resistance to abrasions, tears, and chemical contaminants. The combination of high-performance elastomers and durable, heat-resistant fabrics ensures that components remain functional in the most demanding conditions – ranging from flash fire protection to extreme mechanical stress – and offers purchasers a high-value, long-term solution for mission-critical systems.
Flexibility
Custom rubber products and fabric-reinforced products are flexible in design and thus are well suited for meeting a wide variety of requirements. They are designed to be rigid or flexible depending on the specialized compounds formulated for specific applications. The ability to adjust flexibility in a rubber compound is an important factor in a product’s design and material selection.
Processability
Specialized applications may require custom-engineered rubber compounds. Custom rubber molders, such as RD Rubber, produce products utilizing elastomeric material with specified properties to meet the critical-to-function requirements of demanding applications.
These rubber compounds are manufactured utilizing methods such as rubber compression molding, rubber transfer molding, rubber injection molding, and liquid-silicone rubber molding.
