Description
If you’ve got an unused hydraulic port or need to seal off a test opening, this little 1/8-inch NPT plug is exactly what you need. When you’re working on hydraulic systems—whether it’s a loader, three-point hitch, or remote valve setup—sometimes you need to cap off a port to maintain pressure and keep contaminants out. This threaded plug screws right in and seals things up tight so you can get back to work.
What You’re Getting
- Standard 1/8-27 male NPT threads that fit hydraulic ports and test openings
- 7/16-inch hex head makes installation and removal easy with common tools
- High-pressure rating up to 6,000 PSI handles typical hydraulic system pressures
- Direct replacement for worn or damaged plugs without adapters
Built for Real Farm Work
This plug works on any tractor or equipment with 1/8-inch NPT female ports—that covers most hydraulic systems you’ll find on loaders, three-point hitches, remote valve blocks, and implement circuits. Whether you’re sealing off unused ports on a multi-spool valve or plugging test points after hydraulic work, this fitting handles the pressure and keeps your system clean.
Made to Last
AgSmart builds these plugs to handle the vibration, pressure cycles, and temperature swings that hydraulic systems dish out. The threads are cut clean and the material stands up to hydraulic fluid without degrading or swelling over time.
Installation Notes
Thread this plug in by hand first to avoid cross-threading, then snug it up with a 7/16-inch wrench. Don’t over-tighten—the threads and a little thread sealant do the sealing work. If you’re removing an old plug that’s been in place for years, a little penetrating oil helps it come out easier.
