Plastic One-Way Check Valves (Non-Return Valves) for Liquid, Gas, Fuel & Air. These plastic one-way non-return check valves are designed to allow fluid or gas to flow in only one predefined direction while completely stopping reverse backflow. Equipped with barbed hose connectors in six commonly used sizes, they directly fit flexible hoses without extra clamps or complicated assembly work. Built from high-performance engineering plastic, this valve series delivers excellent resistance to heat, oil, ozone, acids and alkalis, making it a reliable professional fluid control component. An integrated directional flow arrow is printed clearly on each valve body for fast and error-free installation. Product Name : Plastic One-Way Check Valve / Non-Return Valve. Available Hose Barb Outer Diameter : 3 mm, 4 mm, 6 mm, 8 mm, 10 mm, 12 mm. Size Matching Rule 3 mm barb fits hose with 3 mm inner diameter, the same matching logic applies to all other sizes. Body Material : Engineering plastic. Cracking Opening Pressure 1.5 bar. Marking : Flow direction arrow printed on valve housing. Wide medium compatibility : Works stably with water, gasoline, diesel fuel, motor oils, compressed air and multiple other liquid and gaseous media. Outstanding chemical & temperature resistance : Withstands continuous operating temperatures up to 130? ; features reliable resistance against ozone aging, oil corrosion, acids and alkalis for long service life. Clear flow direction indicator : Molded arrow on each valve body explicitly labels the correct fluid flow direction, eliminating installation mistakes. Tool-free quick installation : Barbed hose ends lock tightly into flexible tubing automatically; no extra assembly steps, pipe clamps or accessories needed for mounting. Compact integrated structure : Small footprint allows installation in confined engine bays, pipeline routes and tight equipment spaces. Automotive & Off-Road Vehicles.
