90 Male Elbow #3 to 1/8 NPT Steel Fitting

The 90 Male Elbow #3 to 1/8 NPT Steel Fitting is a critical pneumatic and hydraulic adapter engineered for fuel system, air suspension, and brake line applications on modified vehicles. This elbow fitting connects two tubes at a 90-degree angle, allowing technicians and builders to route lines around tight engine bays, chassis modifications, and custom plumbing layouts without kinks or flow restrictions. Whether you're upgrading a fuel delivery system, installing air management equipment, or fabricating custom brake lines on a performance build, this fitting bridges the gap between #3 (typically 3/16-inch) tubing and standard 1/8 NPT (National Pipe Thread) ports found on manifolds, regulators, and solenoids.

Machined from steel and designed to A-1 PRODUCTS' exacting standards, this 90-degree elbow maintains consistent internal diameter to minimize turbulence and pressure drop across fuel rails, air lines, and hydraulic circuits. The male configuration on one end threads directly into NPT ports with zero-degree seat geometry, creating a leak-free, vibration-resistant joint critical on high-performance and race-ready platforms. The compact 2.9-inch length and precise 90-degree angle eliminate the need for multiple fittings or custom bends, reducing assembly time and potential weak points in your system. Steel construction resists corrosion in both wet engine bays and salt-exposed underbody environments, while maintaining structural integrity under pressure cycling and thermal cycling common to modified fuel systems and pneumatic suspensions.

This fitting is ideal for street-strip mechanics, engine builders, and suspension fabricators who demand reliable, repeatable tubing routes in confined spaces. Installation is straightforward: thread the NPT male end into your manifold or regulator port using appropriate pipe thread sealant (PTFE tape or thread locker), then connect your #3 tubing to the opposite elbow end using compression or barbed fittings as needed. Compatible with fuel, air, and low-pressure hydraulic systems, this adapter is a staple in nitrous kits, turbo intercooler plumbing, air management arrays, and custom brake proportioning valve setups. Keep several in your shop inventory—the lightweight design (0.05 lbs) and universal 90-degree geometry make this fitting an indispensable solution for any line routing challenge.
