Based in Dongguan, Guangdong—China’s premier hub for automotive rubber component manufacturing—HS specializes in bespoke automotive silicone rubber sealing components, engineered as weather-resistant door gaskets, high-temp engine seals, and dust-proof window seals for automotive and industrial machinery applications. Our EE-916-C2 silicone rubber seal is precision-crafted via moulding processing to meet the stringent performance standards of the automotive industry, combining material versatility, full customization, and high-temperature resistance to deliver reliable machinery accessory solutions for automotive manufacturers worldwide. Whether you require standard silicone rubber seals for industrial machinery or bespoke custom-shaped sealing components for automotive systems, our factory-direct capabilities ensure consistent quality, on-time delivery, and cost-effective solutions tailored to your automotive sealing needs.
Core Features of Our Silicone Rubber Seals Our silicone rubber seals stand out for their weather resistance, high-temperature performance, and custom design flexibility—key traits that make them ideal for automotive door gaskets, engine seals, dust-proof window components, and industrial machinery accessories.First, the material quality of our silicone rubber seals is unmatched. We utilize premium silicone rubber (supplemented with EPDM, NBR, and NR options) that delivers exceptional high-temperature resistance (withstanding up to 250°C) for engine seals, while also offering superior weather resistance to UV rays, rain, and extreme temperatures for door and window gaskets. This formulation ensures silicone rubber seals maintain structural integrity and sealing performance in both under-hood automotive environments and exterior weather-exposed applications.Second, bespoke customization defines our silicone rubber seals. Our moulding processing achieves a tolerance of ±0.05mm, ensuring custom-sized and custom-shaped silicone rubber seals create airtight, dust-proof seals for automotive windows, weather-resistant barriers for door frames, and leak-proof seals for engine components. We offer custom colors per customer’s request and customized logo printing, aligning silicone rubber seals with automotive brand identity without compromising functionality.Third, durability is embedded in every silicone rubber seal we produce. The robust material composition resists wear, chemical degradation (from oils and road salts), and mechanical stress, extending the service life of automotive sealing components and industrial machinery accessories while reducing maintenance costs.
Competitive Advantages of Our Silicone Rubber Seals Choosing our silicone rubber seals means partnering with a manufacturer with 20+ years of automotive rubber processing expertise, prioritizing quality, customization, and customer-centric service for automotive and industrial applications. Bespoke Customization & Scalable Production We offer a MOQ of 500 pieces for silicone rubber seals, making our solutions accessible to small and medium-sized automotive component suppliers, while our 10,000-square-meter production facility and 2000+ existing molds enable scalable production to meet bulk orders for major automotive brands. Custom sizes, shapes, and material blends (silicone/EPDM/NBR/NR) for silicone rubber seals are available to fit any automotive door, window, engine component, or industrial machinery accessory. Rigorous Quality Control & Performance Testing Every silicone rubber seal undergoes 100% quality inspection before shipment, including high-temperature resistance testing, weather resistance validation, dimensional verification, and dust-proof performance checks—ensuring zero defects and adherence to automotive industry standards. Our strict quality control processes guarantee silicone rubber seals meet the precision and durability benchmarks required for automotive sealing components and industrial machinery applications.

Technical Expertise & 24/7 Support Our team of automotive rubber engineering specialists provides 7×24 online support for silicone rubber seal inquiries, offering guidance on material selection and seal design optimization for weather-resistant door gaskets, high-temp engine seals, and dust-proof window components. We leverage deep automotive industry knowledge to solve complex sealing challenges, ensuring silicone rubber seals deliver optimal performance in all automotive environments.
Applications of Our Silicone Rubber Seals Our versatile silicone rubber seals serve critical sealing roles in automotive and industrial settings, thanks to their weather resistance, high-temperature performance, and dust-proof design:
Automotive Door Gaskets: Silicone rubber seals act as weather-resistant barriers for car and truck door frames—their flexibility and UV resistance prevent water, wind, and noise from entering the cabin, enhancing passenger comfort and vehicle durability. High-Temp Engine Seals: Custom-shaped silicone rubber seals seal engine blocks, valve covers, and coolant lines—their high-temperature resistance prevents oil and coolant leaks, optimizing engine performance and reducing emissions in automotive powertrains. Dust-Proof Window Seals: Silicone rubber seals fit automotive window channels and sunroof frames—their tight, custom fit blocks dust, debris, and rain from entering the cabin, while weather resistance ensures long-term performance in all climates. Industrial Machinery Sealing: Silicone rubber seals serve as machinery accessories for automotive manufacturing equipment—their high-temperature resistance and durability withstand the heat and vibration of production line machinery, reducing unplanned downtime. Commercial Vehicle Sealing: EPDM-blended silicone rubber seals are adapted for truck and bus door/window systems—their heavy-duty weather resistance and dust-proof performance withstand the rigors of long-haul transportation and harsh road conditions.
At our Dongguan manufacturing facility, we leverage a team of over 100 skilled professionals and state-of-the-art moulding processing equipment to produce silicone rubber seals that exceed industry standards. Our commitment to quality is backed by ISO 9001 and ISO 14001 certifications, validating the reliability and sustainability of our silicone rubber seals for international automotive and industrial markets. We back all silicone rubber seals with a 3-year warranty: if unused silicone rubber seals develop quality issues within this period, we offer free returns and replacements. Whether you need bespoke weather-resistant door gaskets for passenger cars, high-temp engine seals for commercial vehicles, or dust-proof window components for industrial machinery, we deliver silicone rubber seals that combine performance, durability, and value—engineered for the road, built to seal.
