1/2 MPT Allen Pipe Black

The 1/2 MPT Allen Pipe Black is a precision hydraulic and pneumatic fitting designed for systems requiring secure, leak-free connections in high-pressure applications. This aluminum plug fitting serves technicians, engineers, and equipment maintenance professionals who need reliable port closure solutions for fluid transfer systems. The allen head design allows controlled installation and removal using standard hex key tools, making it ideal for both field service and permanent system installations.

Manufactured by FRAGOLA, this 1/2-inch NPT (National Pipe Taper) threaded fitting is machined from aluminum and features a black anodized finish that resists corrosion and oxidation in demanding industrial environments. The anodized coating protects the aluminum from degradation while maintaining excellent chemical resistance and durability. The allen head configuration provides superior grip and torque control compared to slotted alternatives, reducing the risk of tool slippage during installation on pressurized systems. Compact dimensions (1.4 x 0.85 x 4.25 inches) and minimal weight (0.02 lbs) make this fitting suitable for space-constrained applications without compromising structural integrity.

This fitting is essential for anyone closing unused 1/2-inch NPT ports in hydraulic systems, air compressors, fuel delivery assemblies, and irrigation equipment. Maintenance technicians benefit from its straightforward installation process—a simple hex key provides the mechanical advantage needed for proper seating without over-torquing. The black anodized aluminum construction is compatible with petroleum-based hydraulic fluids, synthetic oils, air, water, and most industrial solvents. Replacement or retrofit projects benefit from FRAGOLA's reputation for precision engineering and OEM-quality manufacturing standards.
