Oil Inlet Fitting 3/8NPT to -10 x 3in

The ALLSTAR PERFORMANCE Oil Inlet Fitting 3/8NPT to -10 AN x 3in is a purpose-built fluid transfer adapter engineered for high-performance engine oil systems in racing and motorsports applications. This extended straight inlet fitting bridges 3/8-inch NPT (National Pipe Thread) supply lines to -10 AN (AN10) male connections, providing a clean, leak-free oil pathway in tight engine compartments where standard fittings create clearance conflicts.

The 3-inch extended length accommodates complex plumbing layouts common in custom engine builds, turbocharged installations, and fuel-injected conversions where oil filter relocation or external cooler systems demand flexible routing. Black anodized aluminum construction provides corrosion resistance in engine bay environments while maintaining a lightweight profile—critical for weight-conscious race builds. The -10 AN male end accepts standard -10 hose and fitting combinations widely available in the motorsports aftermarket, ensuring compatibility across multiple manufacturers and system configurations. NPT threads provide a secure, pressure-rated connection on the supply side without requiring additional fittings.

This adapter addresses a specific gap in plumbing flexibility for drag racing, road racing, and street performance applications where OEM oil paths are inadequate or incompatible with aftermarket pump and filter mounts. Engine builders and performance technicians rely on ALLSTAR fittings to maintain system integrity under sustained high oil volume and pressure demands. The straight configuration minimizes turbulence and pressure drop—important factors in maintaining consistent oil delivery to critical bearing surfaces during extended power runs.

For anyone assembling or modifying a performance oil system where standard components don't fit, this ALLSTAR inlet fitting delivers the dimensional flexibility and material durability needed to keep oil flowing reliably under racing conditions.
