Oil Pressure Fitting #4 90 Deg Black

The Oil Pressure Fitting #4 90 Deg Black from King Racing Products is a precision adapter designed for custom engine monitoring systems, fuel systems, and high-performance cooling line applications where space constraints or routing requirements demand a right-angle connection. This fitting serves as an essential component in modern engine builds—whether you're installing auxiliary gauges, turbo coolers, or secondary oil circuits—where standard straight fittings won't accommodate your plumbing geometry. Engineered by a manufacturer known for reliability in racing and street performance applications, this 90-degree adapter ensures proper flow while eliminating stress on hose runs and sensor ports.

The 90-degree bend eliminates the need for bulky hose elbows or custom fabrication, offering a compact, direct transition from one port to another at a right angle. The black powder-coat finish resists corrosion and oil degradation, maintaining appearance and durability in underhood environments where heat cycles and chemical exposure are constant stressors. This compact fitting—weighing just 0.02 lbs—integrates seamlessly into tight engine bays and transmission tunnels, making it ideal for supercharged, turbocharged, or naturally aspirated builds where every inch of clearance matters. The #4 size specification indicates standard AN fitting dimensions, ensuring compatibility with common gauge lines, cooler circuits, and OEM-derived sensor ports found on both street and race vehicles.

Mechanics and engine builders rely on this fitting for engine oil pressure monitors, transmission cooler feeds, intercooler drain lines, and catch-can plumbing where direct 90-degree access saves fabrication time and cost. If you're upgrading turbo systems, installing remote oil filtration, or routing auxiliary cooling circuits on LS, small-block Chevy, Ford modular, or import platforms, this adapter provides the clean, reliable connection point your build demands. Verify your specific AN port size and thread pitch before ordering; this fitting represents the quality standard expected in professional racing shops and serious street-performance builds where reliability cannot be compromised.
