This is a medical round rubber gasket. It is fabricated from EPDM. It features a hardness of 70±5°. It has a reddish-brown, annular split-body design. Its structure consists of a circular ring. It has symmetrically distributed grooves and positioning protrusions on the surface. It has an open slit at the edge. This slit design allows for flexible adaptation to medical device interfaces of varying diameters. It ensures a precise fit into the mounting position.As a critical component for clinical equipment, it complies with the rigorous standards of Medical Device Seals and Medical Grade Silicone Seals. It is fully compatible with the application requirements of Sterile Medical Seals and Pump Valves and Sealing Parts for Testing Equipment.
Product Features
1. Functions
1)Precision Sealing for Medical Equipment:It serves as a key component for the housings or interfaces of medical devices (such as monitors, anesthesia machines, and ventilators). It fills the microscopic gaps on the mating surfaces of the equipment. It blocks moisture, medical fluids, blood, or external dust from invading the equipment interior. It ensures the hygiene of the medical environment and the operational safety of the device. This performance is essential for maintaining the integrity of Detection Device Seals and sensitive diagnostic instruments.
2)Shock Absorption and Buffering Protection:It leverages the elasticity of EPDM. It cushions mechanical vibrations and shocks generated during equipment transportation, movement, or daily use. It reduces friction noise between components. It protects precision electronic elements from vibration damage.
3)Installation and Positioning Assistance:The split-body structure (with an open slit) combines with surface positioning protrusions. It allows for quick snapping into the equipment mounting groove. It achieves "plug-and-play" functionality. This prevents the gasket from shifting or falling off during equipment assembly, disassembly, or maintenance.
2. Performance Characteristics
1)EPDM Material + 70±5° Hardness Balances Sealing Force and Deformation Resistance:EPDM (Ethylene Propylene Diene Monomer) boasts excellent aging resistance, weather resistance, and chemical resistance (water, weak acids/bases). The 70±5° medium-high hardness setting not only ensures the resilience of the gasket under compression to guarantee non-failure sealing. It provides sufficient structural strength to avoid permanent deformation (creep) under long-term pressure. This durability aligns with the standards of Lab Equipment Gaskets and high-reliability medical accessories.
2)Split-Body Open Design Enhances Assembly Efficiency:The open slit design at the edge provides good radial flexibility. It allows the gasket to be snapped in or removed directly without disassembling the entire equipment component. This greatly simplifies the assembly and maintenance process of medical equipment. It reduces labor costs.
3)Precision Dimensions and Surface Texture for Medical-Grade Tolerances:Strictly controlled dimensional tolerances (meeting medical-grade standards) ensure a perfect fit with the equipment housing. The surface grooves and protrusion textures not only increase visual recognition. They help disperse compressive stress, improving sealing reliability. This precision is crucial for Testing Instrument Sealing Parts and high-precision fluid systems.
4)Environmentally Friendly and Non-Toxic for Medical Environments:The material is non-toxic, odorless, and free of extractables. It complies with RoHS and medical device biocompatibility standards. It poses no health risks to the medical environment or the healthcare workers/patients in contact with it.
3. Application Scenarios
1)In-Vitro Diagnostic (IVD) Equipment:It is suitable for housing sealing or fluid path interface sealing in biochemical analyzers and blood analyzers. It prevents reagent volatilization or sample liquid leakage. It meets the strict requirements of Medical Vial Cap Seals in diagnostic fluid control.
2)Life Support Equipment:It is used for housing protection and sealing in ventilators and anesthesia machines. It blocks dust and moisture in the air to protect internal high-pressure gas paths and electronic boards. It is a reliable choice for medical silicone seal applications in critical care devices.
3)Monitoring and Treatment Equipment:It is applicable for the panel and housing connections of monitors and infusion pumps. It provides dustproof and waterproof (IP rating) protection. It complies with the quality standards of Pump Valves and Sealing Parts for Testing Equipment in monitoring systems.
4. Pain Point Solutions
1)Solving Medical Equipment Sealing Failure:Ordinary sponges or low-hardness rubber gaskets are prone to aging and collapse. It leads to a decline in equipment protection levels. The aging resistance and 70° hardness of EPDM can maintain sealing performance for a long time. It ensures the equipment's IP protection rating. It enhances the reliability of Detection Device Seals.
2)Resolving Gasket Installation Difficulty and Falling Off:Traditional solid O-rings or integral gaskets require removing numerous screws for installation. They are prone to falling off or being lost during maintenance. The open split design enables quick and non-destructive installation. The positioning protrusions effectively prevent displacement. It improves the assembly efficiency of Lab Equipment Gaskets.
3)Addressing Vibration Noise and Component Wear:Rigidly connected equipment housings are prone to resonance noise during operation. The elastic buffering of the EPDM gasket can effectively absorb vibrations. It reduces noise and extends equipment life. It optimizes the performance of Testing Instrument Sealing Parts in high-precision instruments.
4)Solving Material Deterioration Caused by Chemical Corrosion:In hospital disinfection environments, ordinary rubber is susceptible to corrosion by alcohol or disinfectants. EPDM possesses good chemical resistance. It can withstand wiping and fumigation with conventional medical disinfectants. This is a key requirement for Medical Vial Cap Seals and reusable medical silicone seal applications.
