Oil Inlet Fitting 1/2NPT to -12 x 3in

The Oil Inlet Fitting 1/2NPT to -12 x 3in is a precision adapter designed for high-performance engine oil system modifications and custom cooling circuit installations. This fitting is essential for builders upgrading oil cooler lines, turbo feed systems, or auxiliary filtration rigs on street and race engines.

Constructed to handle sustained oil pressure while maintaining thread integrity, the Oil Inlet Fitting converts a 1/2-inch NPT (National Pipe Thread) male port into a -12 AN (dash-12) female connection that accepts -12 hose or hard-line assemblies. The fitting is engineered to minimize potential leak paths in critical lubrication systems, ensuring reliable performance under varying oil temperatures and flow rates.

Professional engine builders, performance shops, and dedicated enthusiasts rely on this fitting for various applications, including LS and small-block Chevy engines. Its design allows for installation in tight spaces common to modern engine compartments, making it a versatile choice for any performance upgrade.
