Description
When you’re dealing with hydraulic systems that use different connection types, you need the right adapter to make everything work together properly. This straight hydraulic adapter connects a 9/16-18 male ORB (O-ring boss) fitting to a 3/8-18 female NPSM (National Pipe Straight Mechanical) swivel connection, solving those mismatched thread problems that can stop you dead in your tracks.
What You’re Getting
- Straight-through design maintains consistent flow without sharp bends that restrict pressure
- 4000 PSI operating pressure rating handles demanding agricultural hydraulic systems
- Swivel female end allows for easy connection without twisting attached lines
- 11/16″ hex body provides a solid grip for installation and removal
- Quality construction that seals tight and stays leak-free under pressure
Built for Real Farm Work
This adapter is essential for connecting hydraulic components with different thread types—something you’ll run into when mixing OEM parts with aftermarket hydraulics, or when adding accessories like hydraulic motors, cylinders, or auxiliary valves. The ORB connection uses an O-ring seal for reliability, while the NPSM swivel end makes connections easier in tight spaces where you can’t turn the whole assembly.
Made to Last
Agricultural hydraulics take a beating from vibration, pressure spikes, and constant use. This adapter is built with quality materials and proper thread tolerances to handle the demands of farm equipment. The O-ring boss seal prevents leaks better than pipe thread alone, and the swivel feature reduces stress on connected lines.
Good to Know
Make sure to use the correct O-ring for the ORB connection—it’s critical for a proper seal. The 7/8″ nut hex on the swivel end gives you good leverage for tightening without overdoing it. When installing, thread the adapter in by hand first to avoid cross-threading, then snug it up with the appropriate wrench size.
