KZE Series Hydraulic Quick Couplers

Our KZE series hydraulic quick couplers (ISO 7241-1 A type) are designed for fast, tool-free connection and disconnection of hydraulic lines. Made of high-quality carbon steel (stainless steel optional) with precision machining, these quick couplings provide reliable leak-free performance under high pressure, suitable for hydraulic systems, construction machinery, agricultural equipment, and industrial automation. The double shut-off design prevents fluid leakage and air entry during disconnection, ensuring system safety. Available in various sizes (G1/8 to G1) and thread types (BSP, NPT, metric) to match your application requirements.

Key Features

✅ Fast & Tool-Free Connection: Quick connect/disconnect design saves time during equipment maintenance and hose replacement.
✅ Leak-Free Performance: Precision sealing and double shut-off valves prevent fluid leakage, ensuring system safety and reducing waste.
✅ High Pressure Resistance: Rated working pressure up to 35MPa (5000PSI), suitable for most industrial and mobile hydraulic applications.
✅ Durable Construction: Carbon steel body with zinc plating (corrosion-resistant), optional stainless steel for harsh environments.
✅ Universal Compatibility: ISO 7241-1 A type design fits standard couplers; available in various thread sizes (BSP, NPT, metric) for global applications.
✅ Safety Lock Design: Ball-locking mechanism prevents accidental disconnection under pressure, ensuring operator safety.
