Based in Dongguan, Guangdong—China’s leading hub for medical silicone component manufacturing—HS specializes in custom-sized silicone diaphragms, engineered as non-toxic, flexible sealing components for medical pumps, infusion pumps, blood pressure monitors, and industrial machinery applications. Our EE-917-C2 silicone rubber gasket seals (also referred to as silicone rubber seals) are precision-crafted via moulding processing to meet the stringent safety and performance standards of the healthcare industry, combining medical-grade compliance, high-temperature resistance, and full customization to deliver reliable machinery accessory solutions for medical device manufacturers worldwide. Whether you require standard silicone rubber seals for industrial machinery or bespoke custom-sized diaphragms for infusion pumps, our factory-direct capabilities ensure consistent quality, on-time delivery, and cost-effective solutions tailored to your medical sealing needs.
Core Features of Our Silicone Diaphragms Our silicone diaphragms and silicone rubber seals stand out for their medical-grade safety, flexibility, and precision sealing performance—key traits that make them ideal for medical pumps, infusion pumps, blood pressure monitors, and industrial machinery accessories.First, the material quality of our silicone diaphragms is unmatched. We utilize premium medical-grade silicone rubber (supplemented with EPDM, NBR, and NR options) that is non-toxic, biocompatible, and compliant with global medical device standards (ISO 13485, FDA), ensuring silicone rubber seals are safe for use in contact with bodily fluids and sensitive medical equipment. This formulation also offers exceptional high-temperature resistance (withstanding up to 230°C) and flexibility, maintaining structural integrity during repeated actuation in medical pumps while delivering airtight, leak-proof sealing performance.Second, custom-sized precision defines our silicone diaphragms. Our moulding processing achieves a tolerance of ±0.05mm, ensuring custom-sized and custom-shaped silicone rubber seals fit seamlessly into infusion pump chambers, blood pressure monitor sensors, and medical pump valves—eliminating gaps that compromise accuracy or safety. We offer custom colors per customer’s request and customized logo printing, aligning silicone diaphragms with medical device brand identity without compromising functionality or biocompatibility.Third, durability is embedded in every silicone diaphragm we produce. The robust silicone composition resists fatigue from repeated flexing, chemical degradation from medical fluids, and sterilization processes (autoclaving, EO sterilization)—extending the service life of medical pump components and reducing maintenance costs for healthcare equipment manufacturers. Competitive Advantages of Our Silicone Diaphragms Choosing our silicone diaphragms and silicone rubber seals means partnering with a manufacturer with 20+ years of rubber processing expertise, prioritizing medical safety, customization, and customer-centric service for healthcare and industrial applications. Medical-Grade Compliance & Rigorous Quality Control Every silicone diaphragm undergoes 100% quality inspection before shipment, including non-toxicity validation, flexibility testing, high-temperature resistance checks, and dimensional verification—ensuring zero defects and adherence to global medical device safety standards. Our strict quality control processes guarantee silicone rubber seals meet the precision and biocompatibility benchmarks required for infusion pumps, blood pressure monitors, and industrial machinery. Custom-Sized Flexibility & Scalable Production We offer a MOQ of 500 pieces for silicone diaphragms, making our solutions accessible to small and medium-sized medical device manufacturers, while our 10,000-square-meter production facility and 2000+ existing molds enable scalable production to meet bulk orders for major healthcare brands. Custom sizes, shapes, and material blends (silicone/EPDM/NBR/NR) for silicone rubber seals are available to fit any medical pump component or industrial machinery accessory. Cost-Effective Factory-Direct Pricing As a direct manufacturer, we eliminate middleman markups, offering competitive pricing on custom-sized silicone diaphragms without compromising non-toxicity, flexibility, or sealing performance. Our one-stop procurement service streamlines design, prototyping, and production, reducing lead times and supply chain costs for your medical device and industrial machinery component orders. Technical Expertise & 24/7 Support Our team of medical silicone engineering specialists provides 7×24 online support for silicone diaphragm inquiries, offering guidance on material selection and design optimization for infusion pumps, blood pressure monitors, and medical pumps. We leverage deep healthcare industry knowledge to solve complex sealing challenges, ensuring silicone rubber seals deliver optimal accuracy and reliability in clinical settings.
Applications of Our Silicone Diaphragms Our versatile silicone diaphragms and silicone rubber seals serve critical sealing roles in healthcare and industrial settings, thanks to their non-toxicity, flexibility, and high-temperature resistance:
Infusion Pumps: Custom-sized silicone diaphragms regulate fluid flow in infusion pump chambers—their flexibility ensures precise dosage delivery, while non-toxic composition is safe for long-term contact with medications and bodily fluids. Blood Pressure Monitors: Silicone rubber seals act as diaphragms in blood pressure monitor sensors—their precision fit and flexibility enable accurate pressure readings, and medical-grade compliance ensures patient safety. Medical Fluid Pumps: Silicone diaphragms seal peristaltic pump tubes and valve assemblies—their high-temperature resistance withstands sterilization, and durability resists wear from continuous fluid transfer in clinical environments. Laboratory Medical Equipment: Silicone rubber seals serve as diaphragms for diagnostic pump systems—their non-toxicity prevents sample contamination, and custom sizing fits compact lab equipment designs. Industrial Fluid Control Pumps: EPDM-blended silicone diaphragms are adapted for industrial machinery fluid pumps—their flexibility and high-temperature resistance withstand harsh industrial fluids, while leak-proof design optimizes pump efficiency.
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 diaphragms that exceed medical 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 healthcare and industrial markets. We back all silicone diaphragms 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 custom-sized silicone diaphragms for infusion pumps or flexible sealing components for blood pressure monitors, we deliver silicone rubber seals that combine safety, performance, and value—engineered for healthcare, built to perform.
