Based in Dongguan, Guangdong—China’s leading hub for high-performance silicone component manufacturing—HS specializes in waterproof, dustproof, flame-retardant silicone O-rings, gaskets, and sealing strips, engineered as critical sealing solutions for electronic device enclosures and industrial machinery applications. Our EE-918-C1 silicone rubber products (primarily silicone rubber seals) are precision-crafted via moulding processing to meet the strict safety and performance standards of electronics manufacturers, combining high-temperature resistance, multi-protective performance, and full customization to deliver reliable machinery accessory solutions worldwide. Whether you require standard silicone rubber seals for industrial machinery or bespoke flame-retardant gaskets for electronic device enclosures, our factory-direct capabilities ensure consistent quality, on-time delivery, and cost-effective solutions tailored to your electronic sealing needs.
Core Features of Our Silicone Sealing Products Our silicone O-rings, gaskets, sealing strips (collectively silicone rubber products) and silicone rubber seals stand out for their waterproof, dustproof, flame-retardant performance—key traits that make them ideal for electronic device enclosures and industrial machinery accessories.First, the material quality of our silicone rubber products is unmatched. We utilize premium industrial-grade silicone rubber (supplemented with EPDM, NBR, and NR options) that achieves IP68 waterproof/dustproof certification, UL94 V-0 flame-retardant rating, and exceptional high-temperature resistance (withstanding up to 250°C). This formulation ensures silicone rubber seals protect sensitive electronic components from moisture, dust, and fire risks, while maintaining flexibility across extreme temperatures (-40°C to 250°C).Second, precision customization defines our silicone rubber products. Our moulding processing achieves a tolerance of ±0.05mm, ensuring custom-sized and custom-shaped silicone O-rings, gaskets, and sealing strips fit seamlessly into electronic device enclosures—eliminating gaps that compromise protection. We offer custom colors per customer’s request and customized logo printing, aligning silicone rubber seals with electronics brand identity without compromising performance.Third, durability is embedded in every silicone rubber product we produce. The robust silicone composition resists UV degradation, thermal aging, and chemical exposure, extending the service life of electronic device enclosures and industrial machinery components while reducing maintenance costs.
Competitive Advantages of Our Silicone Rubber Products Choosing our silicone rubber products and silicone rubber seals means partnering with a manufacturer with 20+ years of silicone processing expertise, prioritizing safety, customization, and customer-centric service for electronics and industrial applications.

We leverage deep electronics industry knowledge to solve complex sealing challenges, ensuring silicone rubber seals deliver optimal multi-protective performance.
Applications of Our Silicone Rubber Products Our versatile silicone rubber products and silicone rubber seals serve critical protective roles in electronics and industrial settings, thanks to their waterproof, dustproof, flame-retardant design:
Consumer Electronic Enclosures: Silicone O-rings and gaskets seal smartphone, tablet, and laptop casings—their IP68 waterproof/dustproof performance protects internal components from spills and debris, while flame retardancy reduces fire risks. Industrial Control Panel Enclosures: Silicone sealing strips seal electrical control panels—their flame-retardant rating complies with factory safety standards, and dustproof design prevents particle buildup on sensitive circuitry. IoT Device Enclosures: Custom-shaped silicone rubber seals fit smart sensor and IoT device housings—their waterproof performance supports outdoor deployment, and high-temperature resistance withstands ambient heat. Automotive Electronic Enclosures: Flame-retardant silicone O-rings seal in-vehicle infotainment and battery enclosures—their waterproof/dustproof design protects against cabin moisture and road dust, while heat resistance withstands engine bay temperatures. Server Rack Enclosures: Silicone gaskets seal server rack doors and cable entry points—their dustproof performance maintains clean airflow, and flame retardancy meets data center fire safety standards.
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 products 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 electronics and industrial markets. We back all silicone rubber products 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 waterproof silicone O-rings for consumer electronics or flame-retardant sealing strips for industrial control panels, we deliver silicone rubber products that combine safety, performance, and value—engineered for electronics, built to protect.
