Built for Heavy-Duty Farm Work
This fitting is designed for the larger hydraulic systems you’ll find on modern farm equipment – tractors with high-capacity loaders, combines, large hay equipment, and industrial attachments. The 1-1/4 inch hose size handles up to 300 PSI working pressure, making it suitable for return lines and moderate pressure applications where you need good flow capacity.
Made to Last
Hose fittings connect, control, change the direction of, and terminate the flow in piping and hose systems. They are made of materials that resist corrosion, pressure, and wear. This CAT flange fitting is built to the same standards as the original equipment, so you know it’ll hold up to the daily grind of farm work.
Installation Notes
This is a crimp fitting, so you’ll need the proper crimping equipment and dies for installation. Make sure your hose is cut clean and square, and follow the manufacturer’s crimp specifications for proper assembly. The CAT flange design bolts directly to compatible components – just make sure the flange faces are clean and use appropriate O-rings or gaskets as specified by your equipment manual.
