3/8 MPT Allen Pipe Plug Black

The 3/8 MPT Allen Pipe Plug Black is a precision hydraulic and pneumatic fitting engineered for professionals who demand reliability in high-pressure applications. This compact closure fitting seals threaded ports in fluid power systems, fuel lines, and compressed air networks where vibration resistance and leak-free performance are non-negotiable. Designed for both industrial maintenance and custom fabrication, this allen head plug delivers the security required in demanding environments.

Manufactured from aluminum and finished in black anodizing, the 3/8 MPT Allen Pipe Plug combines lightweight construction with superior corrosion resistance. The allen head socket design enables tool-free installation and removal using standard hex wrenches, reducing downtime during system assembly or maintenance. The 3/8-inch male pipe thread (MPT) fitting accommodates industry-standard 3/8 NPT female ports, ensuring compatibility with existing manifolds, cylinders, and reservoir connections. Black anodization provides both aesthetic consistency with tactical and industrial equipment while protecting against oxidation and wear.

Technicians, systems integrators, and equipment manufacturers rely on this fitting to seal unused ports during testing, reconfiguration, or long-term storage. The compact 2.9 x 0.45 x 3-inch profile fits tight manifold spaces without requiring bulky wrenches or adapters. Whether you're balancing a multi-circuit hydraulic system, capping off emergency air lines, or building custom fluid power assemblies, this FRAGOLA-engineered plug delivers consistent performance across temperature and pressure cycles. For industrial shops, mobile service units, or field repairs where reliability cannot be compromised, stock this essential closure fitting.
