Description
When you’re dealing with hydraulic leaks or building new hose assemblies, having the right crimp fitting can save you hours of headaches and keep your equipment running smooth. This Parker 43 Series crimp fitting connects your 1/4-inch hydraulic hose to ORB (O-ring boss) ports with a secure, leak-free connection that handles the pressure demands of farm work.
What You’re Getting
- Rigid straight design provides a solid, no-flex connection that won’t work loose
- Parker quality construction means this fitting will handle whatever pressure your system throws at it
- 9/16-inch x 18 thread pitch fits standard ORB ports found on most hydraulic components
- Requires proper crimping equipment for installation – no shortcuts with hose clamps
Built for Real Farm Work
This fitting works on tractors, skid steers, and implements that use 1/4-inch hydraulic hose for auxiliary functions, remote cylinders, or loader circuits. You’ll find ORB fittings on everything from hydraulic valve adapter plates to remote hydraulic systems and loader connections. The straight, rigid design is perfect when you need a direct connection without any movement or flex.
Made to Last
Parker has been making hydraulic fittings for decades, and this 43 Series fitting shows why they’re trusted by farmers and equipment manufacturers. The precision-machined threads seal properly with O-rings, and the fitting body is built to handle the vibration and pressure cycles that come with daily use.
Installation Notes
This is a crimp-on fitting, so you’ll need access to proper crimping equipment and dies for 1/4-inch hose. If you’re not set up for crimping, most hydraulic shops can install this fitting for you using Parker crimp specifications. Make sure your O-ring is in good shape when connecting to the ORB port – a damaged O-ring will leak no matter how good your fitting is.
