Vibrant Performance -4AN Male to 1/8″ NPT Male Oil Restrictor Fitting Kit

Precision oil flow regulation engineered to safeguard turbocharger dynamic seals from excessive engine oil pressure damage in high-performance motorsport applications.

Engineered Turbocharger Protection

Excessive engine oil pressure is a primary cause of turbocharger seal failure, resulting in exhaust smoke, oil contamination, and turbo blow-by. The Vibrant Performance 10289 Oil Restrictor Fitting Kit provides custom oil volume metering between a standard 1/8″ NPT oil supply port and a -4AN feed line. Machined from lightweight 6061 aluminum alloy with a sleek black anodized finish, this fitting kit features interchangeable threaded jets that allow builders to fine-tune oil flow to exact turbo specifications.

Key Features & Benefits

  • ☑ Interchangeable Restrictor Jets: Includes 0.030″ and 0.045″ threaded jets for precise oil flow control.
  • ☑ Un-restricted Base Flow: Full fitting passage without jet installed measures 0.060″ orifice.
  • ☑ 6061 Aluminum Alloy: Durable, lightweight construction with corrosion-resistant black anodizing.
  • ☑ Universal AN Adaptability: Converts 1/8″ NPT male ports directly to male -4AN flare.
  • ☑ Complete Kit: Includes adapter fitting, two precision restrictor jets, and hex installation key.

Frequently Asked Questions

Unregulated engine oil pressure can overwhelm internal turbo seals, forcing oil past the dynamic piston ring seals into compressor or turbine housings. The Vibrant 10289 restrictor limits oil volume to match the turbo manufacturer's requirement, preventing seal blow-by while maintaining critical bearing lubrication.

Typically, ball-bearing turbochargers require minimal oil flow and utilize the smaller 0.030" orifice jet. Journal-bearing turbochargers require higher oil volume and usually require the 0.045" jet or no jet installed at all (0.060" base orifice). Always check your turbo manufacturer's specified oil feed pressure limits before fitting.

The threaded jets screw directly into the male -4AN flare opening of the adapter using the included Allen wrench. It is recommended to use a tiny drop of medium-strength thread locker to secure the jet inside the fitting during assembly.
