The Oil Restrictor Fitting -3AN x 1/8in NPT from VIBRANT PERFORMANCE is a precision hydraulic adapter designed specifically for turbo and supercharger oil supply systems. This fitting is essential for tuners and builders who need to regulate oil flow to bearing assemblies and turbo centers, ensuring optimal performance in forced induction engine builds.

Engineered with industry-standard AN (Army-Navy) and NPT (National Pipe Thread) port configurations, the -3AN x 1/8in NPT design allows for seamless integration into existing turbo feed lines and restrictor block assemblies. The fitting accommodates standard -3 braided hose or hard line tubing, while the 1/8in NPT port connects directly to gauge ports or secondary feed lines without the need for additional adapters.

This restrictor fitting is crucial for serious turbo builders, motorsport engine shops, and street enthusiasts running aftermarket forced induction systems. By maintaining stable oil pressure across varying engine speeds and boost levels, it significantly contributes to bearing longevity and overall engine reliability.
