Description
When you’re building hydraulic hose assemblies or replacing worn fittings, having the right crimp fitting can make the difference between a solid connection that lasts and one that fails when you need it most. This Parker HY series fitting connects your 3/8 inch hydraulic hose to equipment with 3/4 inch-16 ORB (O-Ring Boss) threads, giving you a leak-free connection that handles farm work pressures.
What You’re Getting
- Straight rigid design that maintains full flow through the connection
- Steel construction built to resist corrosion, pressure, and wear common in farm environments
- Male ORB threading with precision O-ring sealing for leak-free connections
- Parker quality that meets original equipment standards
- Designed specifically for crimping to 3/8 inch hydraulic hose
Built for Real Farm Work
This fitting works with tractor hydraulic systems that use ORB connections, commonly found on loaders, three-point hydraulics, and remote valve systems. The 3/8 inch hose size handles medium-flow applications like hydraulic cylinders, motors, and auxiliary equipment connections. It’s used in systems on air compressors, automatic manufacturing operations, and equipment controls in agriculture, mining, road construction, and other demanding industries.
Made to Last
The steel construction resists the corrosion, pressure, and wear that come with hydraulic applications. The ORB design uses an O-ring seal that compresses when tightened, creating a metal-to-metal backup seal that won’t blow out under pressure. This Parker HY series fitting meets industry standards for hydraulic system reliability.
Installation Notes
This fitting requires proper crimping equipment and dies matched to your hose specifications. For crimp specs, visit Parker Crimpsource to ensure correct crimping pressure and die selection. The ORB connection threads into your equipment’s hydraulic port – use proper torque to compress the O-ring without over-tightening the threads.
