3/4 MPT Hex Pipe Plug Black

The 3/4 MPT Hex Pipe Plug Black from FRAGOLA is a precision hydraulic and pneumatic fitting designed to seal and cap 3/4-inch male pipe thread ports safely and reliably. This plug serves as an essential component in fluid systems, pressure lines, and manifold assemblies where temporary or permanent port closure is required. Whether you're maintaining industrial equipment, servicing hydraulic systems, or assembling custom fluid circuits, a dependable pipe plug prevents contamination, fluid loss, and unwanted pressure leaks.

Constructed from aluminum and finished in black anodized coating, this 3/4 inch NPT hex head plug combines lightweight durability with superior corrosion resistance. The black anodize protects the aluminum base from oxidation and chemical attack, extending service life in demanding environments. The hexagonal head design provides a secure grip point for installation and removal using standard wrenches or sockets, ensuring tight seating without slippage. The tapered NPT (National Pipe Thread) design creates a mechanical wedge seal that tightens as the plug is threaded into the port, eliminating the need for additional sealant tape in most applications.

This fitting is ideal for technicians, hydraulic system installers, and equipment maintenance teams who need quick, dependable port closure. The compact 1.5 x 1.4 x 4.1-inch profile makes it suitable for tight manifold spaces and hard-to-reach mounting points. Installation is straightforward—apply thread sealant if desired, thread the plug clockwise into the 3/4-inch NPT port, and tighten firmly with a wrench. Compatible with standard male pipe thread ports found on pumps, valves, cylinders, and manifolds, this FRAGOLA plug delivers consistent performance across agricultural, industrial, mobile, and stationary fluid systems.
