3/4 Inch Male NPT Hydraulic Plug

Description

When you need to seal off a hydraulic port temporarily or permanently, you want something that won’t let you down. Whether you’re capping off unused ports on a valve block, sealing test points during maintenance, or closing connections during equipment modifications, this 3/4 inch male NPT plug does the job without fuss. It’s one of those simple parts that saves you from big headaches when hydraulic fluid starts leaking all over your shop floor.

What You’re Getting

• Heavy-duty steel construction that handles high hydraulic pressures up to 5500 PSI
• Standard 3/4-14 male NPT threads that fit common hydraulic fittings and valve bodies
• Hex design with 1-1/16 inch hex for easy installation with standard wrenches
• Reliable seal that keeps hydraulic fluid where it belongs

Built for Hydraulic Systems

This plug fits standard 3/4 inch NPT female ports found on hydraulic pumps, valve blocks, cylinders, and manifolds across all brands of farm equipment. You’ll find these ports on everything from loader valves to three-point hitch systems, and they’re often used as test points or auxiliary connections that need to be sealed when not in use.

Made to Last

Hydraulic systems operate at pressures that would blow out cheaper plugs in a heartbeat. This steel plug handles the pressure and temperature swings that come with heavy equipment operation. The threads are precision-cut to ensure a tight seal without overtightening, and the hex head won’t round off when you need to remove it later.

Installation Notes

Use pipe thread sealant or Teflon tape on the threads for a leak-proof seal. Thread it in snug, but don’t overtighten—the tapered NPT threads create the seal, not brute force. Keep a few of these on hand because you’ll find yourself needing to cap ports more often than you’d think during maintenance and troubleshooting.
