4AN 1/4NPT Pipe Plug Hex Head Red 2/pkg

The REDHORSE PERFORMANCE 4AN 1/4NPT Pipe Plug Hex Head in red anodized aluminum is a precision fitting designed for high-performance hydraulic and pneumatic systems. This 932 Series aluminum plug delivers reliable port closure in applications ranging from race car fuel systems to industrial hydraulic lines, offering a compact, corrosion-resistant solution for temporary or permanent line termination.

The 1/4 inch NPT (National Pipe Thread) male connection ensures compatibility with standard hydraulic and pneumatic components across automotive, aerospace, and industrial sectors. Red anodized aluminum construction provides excellent corrosion resistance while maintaining a lightweight profile—critical in weight-sensitive applications like motorsports. The hex head design allows secure installation and removal with standard wrenches, eliminating the need for specialized tools. These plugs ship as a pair, making them ideal for dual-line systems or providing a spare for inventory.

Buyers working with custom hydraulic tuning, race car fuel systems, marine propulsion lines, or industrial fluid transfer rely on REDHORSE fittings for their proven sealing integrity and straightforward installation. Allen head variants like this model are preferred where space constraints demand a lower-profile fastener. The anodized red finish aids in system organization and quick visual identification of port status during maintenance or diagnostics.

REDHORSE Performance is recognized throughout the automotive performance and hydraulic systems industry for consistent thread accuracy and seal reliability. The 932 Series represents the company's standard aluminum fitting line, engineered to withstand moderate pressure environments without the weight penalty of steel alternatives.
