Jiangmen Dasen Launches New High-Temperature Resistant Silicone Seals for Automotive Engines

Jiangmen Dasen Rubber Technology Co., Ltd., a leading manufacturer of custom rubber and silicone components, today announced the release of a new series of high-temperature resistant silicone seals designed specifically for automotive engine applications.

The new seals are engineered to withstand continuous operating temperatures ranging from -50°C to +250°C, with excellent resistance to engine oils, coolants, and other automotive fluids. They are ideal for use in valve covers, oil pans, turbocharger systems, and other high-heat engine environments where conventional rubber seals may degrade prematurely.

“Automotive engines are becoming more compact and powerful, which drives the need for sealing solutions that can endure extreme thermal cycles,” said a company spokesperson. “With our new high-temperature silicone seals, we offer automakers and parts suppliers a reliable, long-lasting solution that reduces leakage risks and maintenance costs.”

Key features of the new product line include:

• Wide temperature tolerance from -50°C to +250°C

• Superior compression set resistance for long-term sealing performance

• Compatibility with various engine oils, fuels, and coolants

• Customizable shapes, hardness, and colors to meet specific engine designs

• ISO-compliant production with full traceability

The seals can be manufactured from VMQ (silicone rubber), FVMQ (fluorosilicone), or custom compounds, depending on customer requirements. Jiangmen Dasen provides a full service from mold design to prototyping and mass production, with lead times as short as 7–10 days for samples.

Initial customer trials have shown that the new silicone seals outperform standard ACM and NBR seals in high-temperature endurance tests, maintaining elasticity and sealing force after over 5,000 thermal cycles.

These products are now available for global OEM and aftermarket customers. Interested parties can request a quote or sample by visiting the company’s website or contacting the sales team directly.
