10AN Male to 10AN Female 45Deg Blue

The 10AN Male to 10AN Female 45Deg Blue adapter from REDHORSE PERFORMANCE is a precision hydraulic fitting engineered for high-performance fuel, coolant, and brake line routing in custom and modified vehicles. As a seasoned mechanic, you'll recognize this 45-degree swivel configuration as essential for navigating tight engine bays and complex plumbing layouts where straight fittings create kinks or stress points. This adapter bridges two 10 AN (JIC) ports with the flexibility needed in turbocharged, supercharged, and heavily modified fuel systems where space and vibration isolation are non-negotiable.

Machined from aluminum and finished in blue anodize, this fitting delivers corrosion resistance and weight savings critical for performance builds. The 45-degree swivel design allows directional adjustment without twisting the hose itself, reducing fatigue cracking at ferrule seats—a common failure point in aggressive fuel and coolant systems running elevated pressures. The 10 AN thread size (equivalent to -10 JIC) accommodates flows up to 60+ GPH, making it suitable for LS swaps, rotary conversions, and high-displacement naturally aspirated engines. Aluminum construction keeps overall system weight minimal while anodized blue finish provides both UV stability and visual appeal in show and street applications.

Installers and fabricators routinely specify this adapter for fuel rails, cooler bypass circuits, and custom intake manifold plumbing on vehicles running aftermarket fuel systems and radiator upgrades. Its lightweight profile—just 0.12 lbs—adds negligible mass to the powertrain while the compact 45-degree geometry (2.85 × 1.15 × 3.8 inches) fits where 90-degree fittings cannot. Use this fitting with standard -10 AN hose (braided stainless or PTFE) and torque to manufacturer spec for your system pressure rating. Whether you're assembling a fuel cell plumbing loom, rerouting coolant on a tight engine bay, or modernizing brake lines on a classic car build, this REDHORSE adapter provides the durability and adjustability serious modifications demand.
