#4 Flare Cap Black

The XRP-XTREME RACING PROD. #4 Flare Cap Black (part number 992904BB) is a precision-engineered aluminum AN fitting cap designed for high-performance fluid systems in automotive, marine, and industrial applications. Constructed from durable aluminum and finished with black anodized coating, this cap provides reliable sealing for AN-4 (1/4-inch) port connections while resisting corrosion in demanding environments.

The black anodized finish offers superior corrosion resistance compared to bare aluminum, making it ideal for applications exposed to salt spray, moisture, or aggressive chemical environments. The AN-4 specification ensures compatibility with standard military-spec AN fittings used throughout aerospace, racing, and heavy equipment systems. Weighing just 0.04 lbs, this compact fitting integrates seamlessly into tight engine bays and equipment enclosures without adding unnecessary weight to your system. The cap's compact dimensions (2.75 x 0.9 x 3.65 inches) allow installation in confined spaces while maintaining full functional integrity.

This fitting cap serves technicians, mechanics, and engineers who require precision AN-4 port protection in high-reliability systems. Whether capping unused ports on fuel distribution blocks, hydraulic manifolds, or cooling system circuits, this cap prevents contamination and fluid loss while maintaining system pressure integrity. Common applications include off-road racing fuel systems, marine propulsion networks, agricultural equipment hydraulics, and emergency backup power systems where component redundancy demands sealed, accessible ports.

The XRP brand specializes in precision fluid-system components engineered for extreme duty cycles. AN-standard fittings and caps represent the baseline specification for military, aerospace, and professional motorsports fluid management, where leakage, contamination, or system failure carries unacceptable operational cost. Sourcing genuine XRP hardware ensures compatibility with OEM components and maintains system certification integrity for regulated applications.
