Description
When you’re working on hydraulic systems, the last thing you need is a fitting that won’t turn properly or starts leaking under pressure. This Parker HY series crimp fitting gives you the reliability of a secure crimp connection combined with the convenience of a swivel that rotates freely, making it easier to route hoses without twisting or binding.
What You’re Getting
- ORFS (O-Ring Face Seal) design creates a leak-proof connection that handles high pressure without weeping
- Swivel movement lets you position hoses exactly where they need to go without fighting tight spaces
- 3/4 inch hose capacity handles substantial flow for larger hydraulic systems
- 1-7/16 inch x 12 thread pitch fits standard ORFS ports on valves, cylinders, and pumps
- Parker quality construction means this fitting will hold up to the pressure and vibration of real farm work
Built for Real Farm Work
This fitting is designed for tractors, combines, and implements that run serious hydraulic systems. Whether you’re replacing worn fittings on your loader, rebuilding cylinders on your planter, or making custom hoses for your hay equipment, the 3/4 inch size handles the flow rates these machines demand. The ORFS connection is becoming standard on newer equipment because it seals better than old-style flare fittings.
Made to Last
Parker builds these fittings to handle the pressure cycles, temperature swings, and contamination that come with hydraulic work. The swivel bearing stays smooth even after thousands of cycles, and the O-ring face seal design prevents the gradual loosening that can happen with threaded connections over time.
Installation Notes
You’ll need the proper Parker crimping dies for the HY series to install this fitting correctly. Make sure your hose is cut square and clean before crimping. The swivel should turn freely after installation—if it binds, check that the crimp didn’t distort the fitting body. A drop of hydraulic oil on the threads makes assembly easier and helps prevent galling.
