When you’re building or repairing hydraulic lines, having the right fitting makes all the difference between a clean job and a messy redo. This male straight thread fitting with O-ring seal connects your 3/8 inch hydraulic hose to equipment with 7/8-14 threaded ports, giving you that reliable connection that won’t back out or leak under pressure.
What You’re Getting
- Rigid male fitting that threads directly into female ports without swiveling
- O-ring seal design that creates a leak-proof connection even at high pressure
- 7/8-14 thread pitch that matches standard hydraulic equipment connections
- Built for 3/8 inch hydraulic hose – the workhorse size for many farm applications
Built for Real Farm Work
This fitting size is common on tractors, loaders, and implements where you need reliable hydraulic flow without the bulk of larger fittings. 3/8 inch hose handles 4,000 PSI working pressure, making it perfect for loader circuits, three-point hitch systems, and auxiliary hydraulics that power everything from post hole diggers to hay spears.
Made to Last
The O-ring seal design handles the pressure cycles and vibration that come with field work. Unlike pipe thread fittings that rely on thread interference, this straight thread design with O-ring provides consistent sealing that doesn’t loosen over time. The rigid construction means no unexpected movement once it’s installed.
Good to Know
Make sure your female port has the matching 7/8-14 threads before ordering – straight thread fittings won’t seal properly on tapered pipe threads. The O-ring sits in a groove on the male fitting, so inspect it for nicks or damage before installation. A light coat of hydraulic fluid on the O-ring helps with assembly and prevents pinching.
