This is a one-way valve sealing ring for the waterway diverter chamber of oral irrigators. It is made of EPDM. Its hardness is 60°A. It has a black appearance.It features an integrated square base structure with mounting functions. Four circular mounting holes are distributed at the four corners of the base. These holes are for fixing to the diverter chamber. A circular through-hole is set in the middle of the base. This hole is to accommodate waterway circulation. A raised annular sealing lip is designed around the edge of the through-hole. It enhances the fitting tightness and sealing performance with the components of the waterway diverter chamber.As a core sealing component for oral care equipment, it complies with the quality standards of Sterile Seals for Dental Device and Medical Grade Silicone Dental Seals. It is compatible with the application requirements of Irrigator Sealing Components and Oral Appliance Gaskets.
Product Features
1. Functions
1)Sealing Waterway GapsIt fills the mating gaps between the waterway diverter chamber and one-way valve components of oral irrigators. It blocks the leakage of high-pressure water flow through the gaps during the operation of the device. This prevents water damage to the irrigator body. It avoids battery short circuits caused by moisture intrusion. It eliminates water pressure loss due to water leakage. This sealing performance meets the strict requirements of Dental Instrument Seals and Oral Care Accessories Sealing for precision waterway systems.
2)Assisting One-Way ConductionIt cooperates with the one-way valve structure. Its raised annular sealing lip fits tightly with the valve core of the one-way valve. It enhances the reverse sealing effect of the valve. It effectively prevents the backflow of high-pressure water flow. It ensures stable water pressure in the waterway diverter chamber. It maintains consistent water outlet pressure of the oral irrigator. It guarantees reliable cleaning efficiency.
2. Performance Characteristics
1)EPDM Material for Waterway Environment CompatibilityEPDM boasts excellent water resistance and resistance to weak acids and alkalis. Long-term contact with clean water, mouthwash and other liquids used in oral irrigators will not cause swelling, stickiness or material degradation. It can stably maintain its sealing performance. It is ideal for the long-term wet working environment of oral irrigators. This material property aligns with the standards of Food Grade Silicone Seals for Oral Care and safe oral care equipment components.
2)60°A Hardness Balances Structural Stability and Sealing PerformanceThe medium-high hardness of 60°A ensures the structural rigidity of the sealing ring. It prevents deformation during installation. It enables precise matching with the mounting dimensions of the diverter chamber. It also retains moderate elasticity. It adapts to minor tolerances between components. This allows the annular sealing lip to fit tightly with the one-way valve and diverter chamber. It avoids poor fitting caused by excessively high hardness. It also avoids permanent deformation due to long-term extrusion caused by excessively low hardness.
3)Integrated Structure Enhances Sealing ReliabilityCompared with flat sealing rings, the integrated design with an annular sealing lip increases the contact area with the mating surfaces. It significantly improves the sealing effect. The mounting holes at the four corners of the base are precisely sized. This ensures the stable fixing position of the sealing ring on the diverter chamber. It prevents displacement caused by the vibration of the oral irrigator during operation. This structural advantage meets the application requirements of Irrigator Air Plugs and high-stability oral care device components.
3. Application Scenarios
1)Waterway Systems of Various Oral IrrigatorsIt is suitable for the one-way valve position of the waterway diverter chamber in household portable oral irrigators, desktop oral irrigators and travel-type oral irrigators. It is especially applicable to high-pressure models with a water outlet pressure of ≥60PSI.
2)Small-Sized Oral Cleaning EquipmentIt can be used in the one-way valve sealing scenarios of small-sized oral cleaning tools with similar structures (such as interdental cleaners).
4. Pain Point Solutions
1)Solving Waterway Leakage ProblemsOrdinary sealing rings are prone to waterway leakage in oral irrigators due to poor water resistance or insufficient fitting tightness. This leads to moisture damage to the internal components of the device, battery short circuits, or reduced cleaning effectiveness caused by insufficient water pressure. This sealing ring achieves stable and reliable sealing through the combination of EPDM material and annular sealing lip design. It completely eliminates waterway leakage.
2)Solving One-Way Valve Backflow ProblemsPoor fitting of sealing components in some one-way valves may cause water flow backflow. This results in unstable water outlet pressure of the oral irrigator and decreased cleaning power. The annular sealing lip of this product enhances the reverse sealing capability of the one-way valve. It effectively blocks water backflow and maintains stable water pressure.
3)Solving Insufficient Durability of Sealing RingsOrdinary sealing rings are prone to aging and failure after long-term contact with water and mouthwash. They require frequent replacement. The excellent water resistance of EPDM material and the deformation resistance of 60°A hardness extend the service life of the sealing ring. They reduce the frequency of maintenance and replacement.
4)Solving Poor Installation AdaptabilityLow-hardness sealing rings are prone to deformation during installation. High-hardness ones tend to have poor fitting tightness. The 60°A hardness of this sealing ring balances structural stability and elasticity. It enables easy installation. It adapts to minor tolerances between components. It ensures consistent sealing performance.
