When you’re dealing with hydraulic systems, you know that every connection matters. This male straight thread O-ring boss fitting gives you a reliable, leak-free connection for your 3/8 inch hydraulic hose with its 3/4-16 thread. Whether you’re plumbing a new hydraulic system or replacing a worn fitting, this is the kind of connection that’ll handle the pressure and keep working season after season.
Key Features
- O-ring boss design creates a secure, leak-proof seal that handles high pressure without weeping
- Straight thread configuration ensures proper alignment and prevents cross-threading during installation
- Rigid construction stands up to vibration and movement without loosening or failing
- Standard SAE thread pitch matches most hydraulic system components
Built for Real Farm Work
This fitting is sized for 3/8 inch hydraulic hose, which you’ll find on implements like smaller hydraulic cylinders, auxiliary circuits, and return lines on loaders and three-point systems. The 3/4-16 thread size is common across many tractor brands and implements, making this a handy fitting to have on hand for repairs or modifications.
Made to Last
Hydraulic fittings take constant pressure cycles and temperature changes, and the O-ring seal prevents the leaks that lead to bigger problems. This fitting’s rigid design handles the stress of field work without backing out or developing play in the connection.
Installation Notes
The straight thread design means you tighten against the O-ring, not the threads themselves. Snug it down until the O-ring compresses properly—you’ll feel the resistance change. A drop of hydraulic fluid on the O-ring helps it seat without damage during assembly.
