Description
When you’ve got an unused fitting port on your hydraulic manifold or need to cap off a pneumatic line for testing, this black iron plug gets the job done right. It’s one of those simple parts that prevents big headaches—no leaks, no contamination, and no costly fluid loss while your equipment sits in the field.
What You’re Getting
- 3/8 inch male NPT threads that fit standard hydraulic and pneumatic systems
- Durable black iron construction resists corrosion and handles farm environment abuse
- Precise threads ensure tight seal without over-torquing or thread damage
- Compact size won’t interfere with nearby fittings or hydraulic lines
Built for Real Farm Work
This plug works on hydraulic manifolds, air compressor systems, and any equipment using standard NPT fittings. You’ll find these threads on everything from loader hydraulics to shop air lines. Whether you’re temporarily capping a port during maintenance or permanently sealing an unused connection, it handles the pressure without backing out.
Made to Last
Black iron construction means this plug won’t rust out like cheap fittings do. It’s designed to handle hydraulic pressures and temperature swings from shop work to field conditions. The threads are cut clean so they don’t gall or bind when you install them.
Installation Notes
Thread in hand-tight first, then use a pipe wrench for the final turn or two—don’t overtighten and damage the threads. A drop of thread sealant helps ensure a leak-free connection, especially on hydraulic systems where pressure matters.
