Built for Real Farm Work
This fitting is designed for use with 1/2-inch hydraulic hose on equipment that uses the JIS (Japanese Industrial Standard) fitting system. You’ll find this thread size on Komatsu dozers, excavators, and other equipment, as well as some hydraulic cylinders and valves on various implements. The 60-degree concave seat design is engineered to create a tight seal when properly assembled.
Made to Last
Quality crimp fittings are crucial for hydraulic system reliability. This fitting is built to handle the pressures and vibration that come with heavy equipment operation. The concave seat design helps distribute stress evenly, reducing the chance of seal failure or connection problems down the road.
Installation Notes
This is a crimp-on fitting that requires proper crimping equipment and dies to attach securely to hydraulic hose. Make sure you’re using the correct crimp specifications for your hose type and this fitting size. The 24×1.5mm thread should be assembled with appropriate hydraulic thread sealant, and avoid over-tightening which can damage the fitting.
