Oil Inlet Fitting 10an Port 3.750 Long

The Oil Inlet Fitting 10AN Port 3.750 Long from Peterson Fluid is an essential component for custom engine oil system builds, particularly in high-performance and racing applications where precision cooling and lubrication control are critical. This fitting serves as the primary inlet connection point in remote oil filtration systems, turbo oil supply lines, and aftermarket oil cooler setups. Whether you're upgrading a naturally aspirated engine or installing forced induction, this inlet fitting ensures reliable oil delivery to components that demand consistent flow and pressure regulation.

Manufactured by Peterson Fluid, a trusted name in performance oil system components, this fitting features a 10AN (AN10) port configuration, which delivers excellent flow capacity for both street and competition use. The 3.750-inch length allows proper spacing and clearance in tight engine bays while maintaining accessible plumbing geometry. The fitting is constructed from durable materials engineered to withstand sustained pressure cycles and temperature fluctuations typical of modified engines, ensuring leak-free performance across extended driving sessions or race events. The precise machining and reliable seal interface make this component ideal for builders who refuse compromise on system integrity.

Mechanics and engine builders commonly specify this inlet fitting for turbo oil supply installations, remote filter kit assemblies, and custom cooling system applications on street rods, track cars, and high-horsepower builds. The 10AN size balances flow requirements with packaging constraints found in modern engine compartments. Installation typically involves secure mounting to the oil supply source with proper thread-locking compound and torque specifications to prevent vibration-induced loosening. This fitting is compatible with AN10 hose, adapters, and fittings throughout the Peterson Fluid ecosystem, making system design straightforward and reliable.
