Based in Dongguan, Guangdong—China’s leading hub for medical silicone component manufacturing—HS specializes in customizable hypoallergenic silicone O-rings, engineered as leak-proof, hygienic seals for medical tubing, oxygen lines, and diverse medical applications. Our OR-C-04 silicone O ring is precision-crafted via moulding to meet the stringent safety and performance standards of the healthcare industry, combining hypoallergenic material composition, full customization, and high-temperature tolerance to deliver reliable sealing solutions for medical device manufacturers worldwide. Whether you require standard silicone O-rings for medical tubing or bespoke custom-shaped seals for oxygen lines, 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 O-Rings
Our silicone O-rings stand out for their hypoallergenic design, high-temperature tolerance, and leak-proof performance—key traits that make them ideal for medical tubing, oxygen lines, and multi-function medical applications.First, the material quality of our silicone O-rings is unmatched. We use premium medical-grade silicone that is hypoallergenic, latex-free, and biocompatible, ensuring silicone O rings are safe for direct contact with human skin and bodily fluids in medical settings. This formulation also offers exceptional high-temperature tolerance (withstanding up to 230°C) and chemical resistance, maintaining structural integrity in sterilization processes (autoclaving, EO sterilization) and ensuring leak-proof seals for oxygen lines and medical tubing.Second, full customization defines our silicone O-rings. We offer custom sizes, custom thickness, and custom shapes to fit any medical device component, from micro-sized silicone O rings for precision medical tubing to large-diameter seals for oxygen line connectors. Our moulding process achieves a tolerance of ±0.05mm, and hardness (20~80 Shore) is adjustable to balance flexibility for oxygen lines and rigidity for high-pressure medical tubing—all while offering custom colors per customer’s request to align with medical device branding.Third, hygienic durability is embedded in every silicone O-ring we produce. The non-porous silicone surface resists bacterial growth and is easy to sterilize, ensuring compliance with medical hygiene standards, while the robust material composition resists wear and compression set, extending the service life of medical tubing and oxygen line seals.

Competitive Advantages of Our Silicone O-Rings
Choosing our silicone O-rings means partnering with a manufacturer with 20+ years of medical silicone processing expertise, prioritizing safety, customization, and customer-centric service for healthcare applications.
Flexible Customization & OEM/ODM Support
We offer comprehensive OEM/ODM services for silicone O-rings, collaborating closely with clients to refine sizes, thickness, hardness (20~80 Shore), and shapes to match unique medical tubing and oxygen line designs. With a MOQ of 500 pieces, our solutions are accessible to small and medium-sized medical device manufacturers, while our 10,000-square-meter production facility scales to meet bulk orders for major healthcare brands.
Rigorous Quality Control & Safety Testing
Every silicone O-ring undergoes 100% quality inspection before shipment, including hypoallergenic validation, leak-proof performance testing, high-temperature tolerance checks, and dimensional verification—ensuring zero defects and adherence to global medical device safety standards (ISO 13485). Our strict testing protocols guarantee silicone O rings meet the precision and hygiene benchmarks required for medical tubing and oxygen lines.
Cost-Effective Factory-Direct Pricing
As a direct manufacturer, we eliminate middleman markups, offering competitive pricing on hypoallergenic silicone O-rings without compromising high-temperature tolerance or leak-proof performance. Our one-stop procurement service streamlines design, prototyping, and production, reducing lead times and supply chain costs for your medical device component orders.

Our team of medical silicone engineering specialists provides 7×24 online support for silicone O-ring inquiries, offering guidance on material selection, hardness optimization, and seal design for medical tubing, oxygen lines, and other medical applications. We leverage deep healthcare industry knowledge to solve complex sealing challenges, ensuring silicone O rings deliver optimal hygienic and performance outcomes.

Applications of Our Silicone O-Rings
Our versatile silicone O-rings serve critical sealing roles in healthcare settings, thanks to their hypoallergenic design, high-temperature tolerance, and leak-proof performance:

Medical Oxygen Lines: Silicone O-rings create leak-proof seals for oxygen concentrator connectors and nasal cannula tubing—their hypoallergenic composition is safe for long-term patient contact, and high-temperature tolerance withstands sterilization between uses.
Fluid Medical Tubing: Custom-shaped silicone O rings seal IV lines, catheters, and drug delivery tubing—their precision fit prevents fluid leaks, and hygienic surface reduces the risk of contamination in clinical settings.
Respiratory Equipment: Silicone O-rings seal ventilator circuits and nebulizer components—their 20~80 Shore hardness balances flexibility and durability, while leak-proof design ensures consistent airflow for patient care.
Diagnostic Medical Devices: Micro-sized silicone O-rings seal blood analysis equipment and sample collection tubes—their hypoallergenic material complies with lab safety standards, and high-temperature tolerance withstands automated sterilization processes.
Surgical Instruments: Sterilizable silicone O rings seal laparoscopic tools and surgical irrigation tubing—their hygienic, leak-proof performance ensures safety in operating room environments and compliance with surgical sterility protocols.

At our Dongguan manufacturing facility, we leverage state-of-the-art moulding equipment and a team of 100+ skilled professionals to produce silicone O-rings that exceed medical industry standards. Our commitment to quality is backed by ISO 9001 and ISO 14001 certifications, validating the sustainability and reliability of our silicone O-rings for global healthcare markets. We back all silicone O-rings with a 3-year warranty: if unused silicone O rings develop quality issues within this period, we offer free returns and replacements. Whether you need hypoallergenic seals for medical oxygen lines or high-temperature tolerant O-rings for sterilizable medical tubing, we deliver silicone O-rings that combine safety, performance, and value—engineered for healthcare, built to seal.
