🔧 Upgrade your flow game — never look back!
The Uenhoy 1/2" check valve is a robust, plastic one-way valve designed to prevent backflow in fuel, gas, air, and liquid systems. Made from wear- and rust-resistant polypropylene, it features a unique pagoda-shaped slot for airtight sealing and non-slip performance. It operates reliably across a wide temperature range (-30°C to 140°C) and resists acids, alkalis, salts, and organic solvents, making it perfect for automotive, industrial, agricultural, and household applications.
