NPT Allen Plug 1/4

The NPT Allen Plug 1/4 from Triple X Race Components is a precision hydraulic and pneumatic fitting designed for high-performance racing and industrial fluid systems. This aluminum plug serves as a secure port closure or adapter point in applications where NPT (National Pipe Thread) connections are standard. Built for users who demand reliability in demanding environments, this fitting eliminates the need for open ports while maintaining system integrity under pressure.

Manufactured from lightweight aluminum and finished in black anodized coating, the NPT Allen Plug 1/4 resists corrosion and oxidation while providing an attractive appearance in visible installations. The allen head design allows for secure tightening using a standard hex key, ensuring consistent torque application without slippage. The 1/4 inch NPT thread specification provides industry-standard compatibility with most hydraulic lines, brake systems, fuel delivery systems, and cooling circuits found in race cars, trucks, and industrial equipment. Black anodizing adds durability and protects the aluminum substrate from environmental degradation.

This fitting is ideal for fabricators, engine builders, and technicians assembling custom hydraulic or pneumatic systems who need quality port plugs that won't compromise system pressure or appearance. Installation is straightforward—simply thread the NPT Allen Plug 1/4 into any 1/4 inch NPT female port and tighten with an appropriately sized hex wrench until snug. The compact 2.6-inch length and minimal 0.01-pound weight make it practical for tight engine bays and tight spaces. Whether closing off unused ports during system testing or providing permanent closure in modular hydraulic designs, this fitting delivers Triple X Race Components' reputation for precision and reliability.
