When you’re working on hydraulic lines or need to cap off unused ports on your tractor, you want a plug that’s going to seal tight and stay put. This 3/8 inch galvanized plug threads right into your MNPT fittings and gives you a leak-proof seal that handles the pressure and vibration that comes with farm work.
What You’re Getting
- 3/8 inch male National Pipe Thread (MNPT) for standard pipe connections
- Galvanized coating resists rust and corrosion from weather and hydraulic fluids
- Square head design makes installation and removal easy with standard tools
- Tapered threads create a secure, pressure-tight seal without needing pipe dope
Built for Real Farm Work
This little plug comes in handy more often than you’d think. Whether you’re capping off hydraulic ports during maintenance, sealing unused connections on remote valve blocks, or plugging test ports on pumps and cylinders, it fits wherever you’ve got a 3/8 inch female pipe thread. The galvanized finish holds up to hydraulic oil, water, and the general abuse that farm equipment dishes out.
Made to Last
The galvanized coating isn’t just for looks—it keeps this plug from rusting out when it’s exposed to moisture and chemicals. The threads are cut clean and deep, so you get a good bite in the fitting without cross-threading or galling. It’s built to stay tight through temperature changes and vibration.
Good to Know
These threads are self-sealing, but a little pipe thread compound never hurts for high-pressure applications. Don’t over-tighten—snug is usually enough with tapered pipe threads. Keep a few of these in your toolbox because you’ll find uses for them when you least expect it.
