Description
When you’re building or repairing hydraulic lines on your equipment, having the right fittings makes all the difference between a job that holds up and one that gives you headaches down the road. This Parker 43 Series crimp fitting connects 1/4 inch hydraulic hose to a 1/2 inch ORB (O-Ring Boss) port, giving you a reliable connection that seals tight and swivels freely for easy installation.
What You’re Getting
- Swivel design lets you position the hose without fighting twist or binding during installation
- ORB male end with O-ring sealing provides a leak-free connection that won’t weep over time
- Crimp-on construction creates a permanent, secure attachment to your hydraulic hose
- Straight configuration keeps your hydraulic lines clean and direct where space allows
- Parker quality means this fitting is built to handle the pressure and vibration your equipment dishes out
Built for Real Farm Work
This fitting works great for hydraulic systems on tractors, combines, balers, and other agricultural equipment where you need to connect smaller hydraulic lines to standard ORB ports. You’ll find 1/2 inch ORB connections on many remotes, valve blocks, and hydraulic cylinders across different brands of farm machinery.
Made to Last
Parker builds these fittings to handle the pressure surges, temperature changes, and constant vibration that come with agricultural hydraulics. The O-ring boss design provides superior sealing compared to pipe threads, while the swivel feature reduces stress on both the fitting and your hose.
Installation Notes
This is a crimp-on fitting that requires proper crimping equipment and dies to attach securely to your hose. Make sure your hose end is cut square and clean before crimping. The swivel action should move freely after installation—if it’s stiff, double-check your crimp diameter against Parker’s specifications.
