Based in Dongguan, Guangdong—China’s leading hub for precision rubber component manufacturing—HS specializes in high-precision tailored silicone rubber seals, engineered as chemical-resistant, leak-proof gaskets and O-rings for laboratory use and industrial machinery applications. Our EE-916-C3 silicone rubber seal is precision-crafted via moulding processing to meet the stringent safety and performance standards of laboratory environments, combining material versatility, full customization, and high-temperature resistance to deliver reliable machinery accessory solutions for labs and industrial manufacturers worldwide. Whether you require standard silicone rubber seals for lab equipment or bespoke custom-shaped gaskets for specialized analytical instruments, our factory-direct capabilities ensure consistent quality, on-time delivery, and cost-effective solutions tailored to your laboratory sealing needs.
Core Features of Our Silicone Rubber Seals Our silicone rubber seals stand out for their high-precision engineering, chemical resistance, and leak-proof performance—key traits that make them ideal for laboratory use and industrial machinery accessory applications.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 chemical resistance to acids, solvents, and corrosive reagents common in laboratory settings, while also offering high-temperature resistance (withstanding up to 250°C). This formulation ensures silicone rubber seals maintain structural integrity and leak-proof performance, even when exposed to harsh lab chemicals and extreme temperatures.Second, high-precision manufacturing 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, leak-proof seals for lab glassware, analytical instruments, and industrial machinery components—eliminating contamination risks and performance issues in critical laboratory processes. We offer custom colors per customer’s request and customized logo printing, aligning silicone rubber seals with lab equipment branding without compromising functionality.Third, durability is embedded in every silicone rubber seal we produce. The robust material composition resists wear, degradation, and compression set, extending the service life of lab gaskets and O-rings and reducing replacement costs for laboratory and industrial facilities alike.

Applications of Our Silicone Rubber Seals Our versatile silicone rubber seals serve critical sealing roles in laboratories and industrial settings, thanks to their high precision, chemical resistance, and leak-proof design:
Laboratory Glassware & Reactors: Silicone rubber seals act as gaskets for lab reactors, beaker lids, and distillation apparatus—their chemical resistance prevents reagent leaks and contamination, while high-temperature resistance withstands heating processes in analytical labs. Analytical Instruments: Custom-shaped silicone rubber seals seal HPLC systems, mass spectrometers, and pH meters—their high-precision fit ensures accurate readings and prevents fluid leaks in sensitive lab equipment. Industrial Lab Processing Equipment: Silicone rubber seals are used as machinery accessories for pilot-scale production equipment in industrial labs—their chemical resistance and durability withstand continuous use with industrial-grade chemicals and high temperatures. Lab Safety Equipment: Leak-proof silicone rubber seals seal chemical storage containers and fume hoods—their chemical resistance reduces the risk of hazardous spills and exposure in laboratory environments. Biochemical Labs: NBR-blended silicone rubber seals are adapted for bioreactors and cell culture equipment—their compatibility with biological reagents and leak-proof performance ensures sterile conditions in biochemical research.
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 laboratory 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 high-precision chemical-resistant silicone rubber seals for laboratory use or leak-proof gaskets for industrial machinery, we deliver silicone rubber seals that combine performance, safety, and value—engineered for labs, built to seal.
