Custom Rubber Seals Manufacturer
Temco Rubber is a specialized rubber seal manufacturer engineering high-performance sealing solutions for rigorous industrial applications. We produce custom rubber seals based on your 2D technical drawings, 3D CAD models, physical samples, or tight dimensional specifications to guarantee complete mechanical system integrity.
Engineering Parameters for Custom Rubber Seals
We do not rely on a "one size fits all" approach. Every custom molded rubber seal is engineered strictly against six technical performance parameters.
Dimensions & Geometry
Precision manufacturing adhering strictly to tight ISO 3302-1 tolerances for both simple cross-sections and complex custom sealing geometries.
Hardness (Durometer)
Formulated across a broad Shore A range (30 to 90 Durometer) to achieve the exact flexibility and sealing force required.
Material Compatibility
Elastomers selected based on chemical exposure targets, preventing degradation upon contact with specific industrial oils, fuels, or gases.
Profile Optimization
Customization of seal profiles to optimize surface contact pressure and minimize wear in high-cycle dynamic applications.
Temperature Range
Engineered to maintain structural elasticity across thermal extremes, from cryogenic conditions up to high-heat industrial setups.
Pressure Requirements
Designed to withstand heavy high-pressure hydraulic impulses or maintain reliable vacuum tightness in critical setups.
Types of Custom Rubber Seals We Manufacture
Our manufacturing capabilities cover a broad spectrum of static, dynamic, and reciprocating sealing products.
Molded Rubber Seals
Intricate components produced via compression, transfer, and injection molding for high dimensional stability.
Custom Profile Seals
Specialized D-strips, P-strips, and complex hollow sealing profiles for enclosures, doors, and hatches.
Rubber Gaskets
Custom flange and housing gaskets designed to eliminate leakage under mating compression.
Rubber O-Rings
Custom-sized O-rings tailored to non-standard groove dimensions and specialized chemical environments.
Elastomer Chemistry for Sealing Applications
Successful seal reliability depends heavily on selecting the correct polymer chemistry for your operational fluid.
NBR (Nitrile / Buna-N)
Excellent resistance to petroleum-based oils, fuels, and hydraulic fluids. The preferred choice for automotive and industrial machinery.
EPDM Rubber
Exceptional resistance to weathering, ozone, UV exposure, and steam. Ideal for outdoor equipment and brake systems.
FKM (Viton®)
Superior performance under aggressive chemical exposure and extreme high temperatures in engines and chemical processing.
Silicone (VMQ)
Wide thermal stability and biocompatibility. FDA-compliant formulations for medical, food-grade, and high-temp setups.
Our Rubber Seal Manufacturing Lifecycle
A controlled engineering lifecycle ensuring zero-defect quality across every production lot.
