Our high-temperature rubber seals are manufactured from premium EPDM and silicone rubber materials using scientific formulations and sophisticated production processes. Designed to withstand extreme temperatures while offering excellent compression deformation resistance and compatibility with various media, these seals maintain stable performance in both static and dynamic high-pressure applications. They effectively prevent leakage, dust, water, and other contaminants from entering, ensuring the normal operation of equipment and pipelines.
We specialize in customization services, providing personalized solutions tailored to your specific requirements including product dimensions, shape, hardness, color, material composition, and other parameters to fully match your application scenarios and technical standards.
Core Product Advantages
Exceptional High-Temperature Resistance
Our silicone rubber seals withstand continuous high temperatures up to 230°C (446°F), with special high-temperature grades reaching 270°C (518°F). EPDM rubber seals maintain stable performance from -40°C to 150°C (-40°F to 302°F). Even under long-term high-temperature operation, they resist hardening, cracking, deformation, or degradation, ensuring reliable sealing in demanding environments such as engine compartments, industrial furnaces, and high-temperature pipelines.
Superior Compression Performance
Our products feature excellent compression set resistance and rebound elasticity. After long-term compression and repeated use, they quickly recover their original shape without permanent deformation, maintaining a tight fit with sealed surfaces. The compression deformation rate is controlled within 15-25% (tested at 175°C for 22h according to ASTM D 395), enhancing sealing reliability and extending product service life.
Customized Solutions for All Needs
We provide full-process custom services. Simply provide drawings, samples, or detailed technical parameters (including size tolerance, hardness, working temperature, pressure, and medium environment), and our professional engineering team will conduct in-depth consultation and program design, complete sample production and testing, and proceed to mass production. We accommodate both standard sizes and special-shaped products, from small batch trial production to large volume orders.

Premium EPDM & Silicone Materials
We use high-purity EPDM and silicone rubber raw materials that are non-toxic, odorless, environmentally friendly, and compliant with international standards including FDA, ROHS, and REACH. EPDM rubber offers excellent weather resistance, ozone resistance, and abrasion resistance with a service life up to 50 years in appropriate environments. Silicone rubber provides good oil resistance, chemical inertness, and sterility, making it suitable for food processing, medical equipment, and other applications requiring high hygiene standards.
Wide Adaptability & Multi-Industry Application
Our products feature strong environmental adaptability and resist erosion from various media including oil, acid, alkali, water, and chemical reagents (depending on material type). They are widely used across automotive, aerospace, electronics, mechanical manufacturing, chemical processing, food processing, medical equipment, HVAC, and construction industries. Applications include O-rings, gaskets, seal strips, compression seals, and custom-shaped seals.
Quality Assurance
We maintain a comprehensive quality management system with strict inspection at every stage from raw material procurement to product delivery. Using advanced testing equipment including tensile testing machines, high and low temperature testing machines, and compression set testing machines, we verify product performance to ensure compliance with technical standards and customer requirements. We provide a quality guarantee period and promptly address any quality issues with replacement or compensation.
