Description
Every hydraulic system needs reliable plugs to seal off unused ports and prevent contamination from getting into your lines. When you’ve got an open NPT port on a manifold, pump, or cylinder that needs to be sealed tight, this heavy-duty plug gets the job done without the hassle of leaks or stripped threads down the road.
What You’re Getting
- 1/4 inch – 18 threads per inch male NPT design fits standard hydraulic ports perfectly
- 6000 PSI pressure rating handles even the most demanding hydraulic applications
- 9/16 inch hex head gives you solid grip for proper installation and removal
- Steel construction stands up to hydraulic fluid, temperature swings, and vibration
- Clean threads and precision machining ensure leak-free seal every time
Built for Real Farm Work
This plug works on any hydraulic system with 1/4 inch NPT ports – from loader valves and cylinder ports to hydraulic pumps and manifold blocks. Whether you’re sealing off an unused remote on your tractor, plugging a port during maintenance, or capping off a test connection, this plug handles the high pressures that farm hydraulics demand.
Made to Last
AgSmart builds these plugs to handle the punishment of agricultural hydraulics. The steel construction resists corrosion from hydraulic fluid and moisture, while the precision threads won’t strip out or cross-thread like cheaper alternatives. At 6000 PSI working pressure, this plug won’t blow out under load.
Good to Know
Clean the port threads before installation and use pipe thread sealant or tape rated for hydraulic use. The 9/16 inch hex makes installation easy with a standard wrench – just snug it down until the threads are fully engaged, but don’t over-tighten and risk cracking the port. Keep a few of these on hand since hydraulic maintenance always seems to require more plugs than you think.
