1/4 MPT Allen Pipe Plug Black

The FRAGOLA 1/4 MPT Allen Pipe Plug Black (MPN 493203-BL) is a precision aluminum fitting designed to seal 1/4-inch NPT (National Pipe Thread) ports on hydraulic and fluid systems. This compact, black anodized aluminum plug features an Allen head socket for secure installation and removal using standard hex key tools, making it ideal for system maintenance, custom fabrication, and fluid line termination in high-pressure applications.

Constructed from aluminum and finished in hard black anodize, this 1/4 NPT pipe plug delivers corrosion resistance and professional appearance in demanding environments. The Allen head design provides superior grip and control compared to slotted alternatives, reducing the risk of tool slippage during installation or removal. The NPT thread standard ensures a tapered seal that tightens as the fitting is threaded in, creating a leak-free connection without requiring additional sealant tape in most applications. Minimal weight (0.01 lbs) and compact dimensions make this fitting suitable for space-constrained manifold assemblies and custom hydraulic configurations.

This fitting is essential for technicians, fabricators, and system integrators working with hydraulic lines, pneumatic systems, or fluid transfer equipment. Whether plugging unused ports during system assembly, replacing damaged fittings, or terminating branch lines in multi-port manifolds, the Allen head design and NPT compatibility make this FRAGOLA plug a reliable choice. Sold individually for convenience in small repairs or as a component in larger fluid system projects.
