Oil Pump Fitting R4 12AN

The Oil Pump Fitting R4 12AN is a precision aluminum adapter designed for high-performance engine oiling systems, particularly those using Peterson R4 oil pumps. This fitting serves as the critical connection point between your oil pump outlet and the engine's oil distribution network, making it essential for builders and technicians who demand reliable fuel and coolant circulation in racing, performance, and custom engine applications. The 12AN port size accommodates standard hose and line connections used in modern performance builds.

Manufactured from aerospace-grade aluminum and finished with black anodizing, this fitting combines lightweight construction with superior corrosion resistance and durability under high-temperature engine environments. The male 12AN thread design ensures secure, leak-free connections when paired with compatible 12AN female ports and hose fittings. Black anodizing not only provides aesthetic appeal but also offers protection against oxidation and extends component lifespan in demanding engine bay conditions where oil pressure and heat cycling are constant stressors.

This fitting is ideal for engine builders, performance shops, and enthusiasts customizing oiling systems on Peterson R4 oil pump platforms. It integrates seamlessly into high-flow oil systems found in street rods, drag racing engines, and circle-track competition vehicles. Installation requires only standard hose and AN fitting tools; the compact dimensions (2.15 x 1.85 x 3.9 inches) allow flexible positioning in tight engine compartment layouts. Weighing just 0.08 lbs, it adds negligible mass while delivering professional-grade reliability and performance.
