Silicone Gaskets High Temperature Sealing Solutions

Room-temperature vulcanizing (RTV) silicone gaskets typically cure within 24 hours at ambient temperature, though full mechanical strength develops over 48–72 hours. Molded and pre-cured silicone gaskets, such as those offered by Detroit Sealing Components, require no curing time and are ready for immediate installation, reducing downtime significantly.

Silicone (VMQ) gaskets outperform standard rubber in high-temperature applications, maintaining flexibility and sealing integrity from -60°C up to 200°C or beyond. However, the best material depends on the specific application — NBR excels with petroleum oils, EPDM handles steam and water well, and FKM/Viton is preferred for aggressive chemical environments.

In high-temperature or UV-exposed environments, silicone seals generally outlast standard rubber compounds such as NBR or EPDM due to their superior thermal stability and ozone resistance. For applications within standard temperature ranges and in contact with petroleum-based fluids, high-quality NBR or HNBR seals may offer comparable or superior service life.

VMQ/Silicone gaskets from Detroit Sealing Components are available in hardness ranges from 45–90 Shore A and are engineered to perform in temperatures typically spanning -60°C to +200°C. Metal-bonded silicone seal configurations can further enhance structural integrity and thermal performance in extreme operating environments.

Yes. Detroit Sealing Components offers fully custom-engineered silicone gasket and metal-bonded rubber seal solutions. Using computer-aided design and finite element analysis, DSC produces components in sizes from 10mm to 320mm, accommodating unique geometries, Shore A hardness requirements, and specialized metal substrate materials including stainless steel and aluminum alloys.

High temperature silicone sealing solutions are widely used in automotive powertrain systems, food and beverage processing, oil & gas pipeline and equipment sealing, aerospace precision components, renewable energy systems, drinking water infrastructure, and general industrial machinery where elevated heat, chemical exposure, or hygiene compliance demands are present.
