Description
When you’re building or repairing hydraulic lines on your tractor or implements, you need fittings that’ll hold up under pressure and keep the fluid flowing where it needs to go. This Couplamatic GW series crimp fitting gives you that reliable connection between your 3/4 inch hydraulic hose and NPT threaded ports on cylinders, pumps, and valves.
What You’re Getting
- Precision-machined male NPTF threads that seal tight without tape or compound
- Rigid straight design that won’t flex or move under pressure
- Factory-quality construction built to handle high-pressure hydraulic systems
- Direct crimp connection ensures a permanent, leak-free bond to your hose
Built for Real Farm Work
This fitting is designed for 3/4 inch hydraulic hose commonly found on mid to large-sized tractors and implements. Whether you’re running a front loader, powering a brush hog, or operating hydraulic cylinders on tillage equipment, this fitting connects your hose to standard NPT-threaded hydraulic components throughout the agricultural industry.
Made to Last
The GW series is built to handle the punishment that farm hydraulics dish out daily. The rigid construction won’t bend or crack under high pressure, and the NPTF threads create a metal-to-metal seal that stays tight through temperature changes and vibration.
Good to Know
This is a crimp-on fitting that requires proper crimping equipment and dies for installation. The NPTF thread design means you won’t need thread sealant—the tapered threads create their own seal when properly tightened. Make sure your hose end is cut clean and square before crimping for the best connection.
