AN to NPT 90 Degree #4 x 1/8

The AN to NPT 90 Degree #4 x 1/8 adapter is a specialized fluid transfer component designed for high-performance plumbing systems where space is at a premium. This fitting bridges the gap between different threading standards, allowing you to connect -4 AN braided hoses to 1/8-inch NPT ports commonly found in engine blocks, fuel rails, or aftermarket gauge sensors. Its 90-degree elbow configuration is essential for routing lines around tight corners or obstructions without kinking the hose, which ensures consistent pressure and flow. Whether you are building a custom fuel system or upgrading a hydraulic line, this adapter provides a leak-free transition for critical automotive or tactical machinery. Understanding the difference between tapered pipe threads and flare fittings is vital for a secure build, and this adapter solves that compatibility challenge efficiently.

Manufactured by Triple X Race Components, this fitting is machined from lightweight aluminum to ensure durability and high-pressure integrity without adding unnecessary weight to your assembly. The black anodized finish provides superior corrosion resistance and a professional, low-profile aesthetic that withstands harsh environmental conditions and chemical exposure. The 4 AN male end features a 37-degree flare for a secure metal-to-metal seal, while the 1/8-inch NPT male end utilizes tapered threads to create a pressure-tight connection within the mating port. Precision machining ensures that the internal flow path remains consistent through the 90-degree bend, minimizing turbulence and potential pressure drops across the joint. These specifications are crucial for maintaining the performance of high-flow fuel or oil systems under heavy operating loads.

This AN to NPT 90 Degree #4 x 1/8 adapter is ideal for professional mechanics, racing teams, and performance enthusiasts who demand reliable specifications for their fluid systems. It is commonly used in fuel pressure regulators, oil pressure sensors, and specialized coolant systems where a compact, angled connection is required for proper clearance. Installation is straightforward for those familiar with AN plumbing standards, though the use of a high-quality thread sealant or PTFE tape is recommended on the NPT side to ensure a perfect seal. By choosing this specific adapter, you ensure compatibility with standard -4 AN hoses while maintaining the structural integrity of your high-pressure fluid lines in any environment. Reviewing your system's clearance and thread requirements will confirm that this 90-degree fitting is the optimal choice for your next project.
