6AN 3/8NPT Pipe Plug Hex Head Clear 2/pkg

The REDHORSE PERFORMANCE 6AN 3/8NPT Pipe Plug Hex Head in clear anodized aluminum delivers a professional-grade sealing solution for high-pressure hydraulic and fuel system applications. This two-pack includes aluminum pipe plugs engineered to seal NPT (National Pipe Thread) ports with reliable integrity under demanding conditions found in racing, marine, and industrial fluid transfer systems.

The 3/8-inch NPT port size accommodates standard industrial and aftermarket hydraulic fittings, while the hex head design allows secure installation and removal with standard wrenches. Clear anodized aluminum construction resists corrosion in moisture-rich environments while remaining lightweight, making these plugs suitable for motorsports, marine applications, and systems where weight savings matter. The hex head profile prevents cross-threading and ensures consistent torque application during installation, critical for maintaining system pressure integrity.

Professionals using custom fuel injection systems, hydraulic brake circuits, and pressurized fluid manifolds rely on REDHORSE Performance fittings to eliminate port leakage without additional sealing compounds. The two-piece packaging allows spare plugs on hand for field maintenance or system reconfiguration. These plugs integrate seamlessly with NPT-threaded ports found in performance carburetors, transmission coolers, turbocharger installations, and marine engine cooling systems where temporary port access is required.

REDHORSE Performance fittings are industry-standard components in drag racing, road racing, and marine propulsion communities where system reliability under extreme operating conditions is non-negotiable. The clear anodized finish provides visual corrosion resistance while maintaining the professional appearance expected in show-quality engine bays and fluid systems.
