7.5*4.2*8mm Silicone / Fluoroelastomer Duckbill Valve Supplier for Medical, Consumer & Home Appliances 5KPA Duckbill Valve ISO10993 Precision Molding Duckbill Water Valve

Reliable sealing, stable opening pressure, and excellent chemical resistance.
Our silicone and fluoroelastomer duckbill valves are designed for precise one-way flow control in demanding applications such as medical devices, liquid dispensers, household appliances, and consumer product packaging. With flexible material options, custom dimensions, and consistent molding quality, these valves help improve product safety, user experience, and long-term reliability.

Our duckbill valves are precision-molded one-way elastomer valves that allow air or liquid to flow in one direction while preventing backflow. They are widely used in products that require controlled dispensing, anti-leakage performance, contamination prevention, and pressure balancing.

We provide both silicone duckbill valves and fluoroelastomer duckbill valves to meet different environmental, chemical, and temperature requirements.

• Silicone duckbill valves are ideal for applications requiring softness, flexibility, and biocompatibility potential.
• Fluoroelastomer duckbill valves are suitable for harsher environments where stronger resistance to chemicals, oils, and elevated temperatures is needed.

Whether you are developing a medical fluid path component, a liquid dispensing closure, or a one-way valve for small appliances, we can support your OEM/ODM requirements with stable quality and fast customization.

The duckbill structure opens under forward pressure and closes automatically when pressure drops or reverses, helping prevent backflow and leakage.

The flexible slit design ensures tight sealing at rest, making the valve suitable for products requiring anti-drip, anti-leak, and contamination control.

Available in silicone and fluoroelastomer (FKM/FPM) to suit different applications, media, and operating environments.

Especially with fluoroelastomer materials, the valve can maintain performance in contact with oils, chemicals, and cleaning agents.

Precision molding helps maintain consistent valve opening characteristics, which is critical for dispensers, pumps, medical devices, and appliance systems.

Suitable for low- and high-temperature working environments depending on the selected rubber compound.

Small size and flexible geometry make duckbill valves easy to install into caps, housings, pumps, reservoirs, tubing systems, and dispensing heads.

We support customization in size, hardness, slit design, color, material grade, and performance parameters based on your project requirements.
