Vibrant -4AN to 1/8in NPT Oil Restrictor Fitting Kit
This Vibrant Performance kit converts -4AN oil lines to 1/8in NPT ports for precise oil delivery to turbos in any performance vehicle. It includes two brass jets to adjust flow rates limiting excess oil that can damage turbo seals. Ideal for custom turbo setups on street or race cars.
Key Features
- 6061 Aluminum Construction: Lightweight durable body resists corrosion handles high pressure in oil systems
- Two Brass Jets Included: 0.035in and 0.040in orifices allow flow adjustment based on turbo size and engine demands
- -4AN Male to 1/8in NPT Male: Direct fit for common turbo oil feed lines and block ports no adapters needed
- Oil Flow Restriction: Reduces oil volume to turbos preventing seal blowout and oil drainback issues
- Threaded Design: Secure installation with O-ring seals for leak-free performance under boost
Product Notes
- Choose jet size by testing smaller orifice first for your setup
- Inspect and clean fittings before installation to avoid contamination
- Compact kit fits easily in toolbox ships in protective packaging
Installation Notes
- Professional installation recommended.
- Thread restrictor into 1/8in NPT oil port apply thread sealant if needed
- Compatible with standard AN hose ends and turbo oil inlets

Fabrication
Fabrication parts and materials provide the raw components needed to build, repair, and modify custom exhaust systems, turbocharger plumbing, intercooler piping, fuel system lines, oil routing, and engine bay heat management on performance and competition vehicles. Stainless steel tubing, titanium tubing, aluminum charge piping, mandrel bends, pie cuts, flanges, merge collectors, V-band clamps, O2 sensor bungs, AN fittings, PTFE hose kits, braided fuel and oil lines, heat shields, and welding supplies are the backbone of any serious custom fabrication project. Professional fabricators, race team mechanics, and advanced DIY builders who want full control over exhaust routing, charge pipe layout, or fuel system plumbing choose raw fabrication materials rather than pre-bent kits because custom fabrication allows fitment solutions that no universal kit can accommodate. Brands including Vibrant Performance, Ticon Industries, Stainless Bros, Radium Engineering, Fragola, and DEI provide th...

Fittings
Automotive fluid system fittings are the hardware that connects hoses, hard lines, and components within fuel, oil, cooling, brake, power steering, and intercooler circuits, and the quality and correct sizing of these fittings directly determines whether a high-performance fluid system remains leak-free under the pressure, temperature, and vibration conditions that race and street performance environments produce. The AN fitting standard, derived from military Aircraft-Navy specifications, provides a consistent thread and flare geometry across fuel, oil, and hydraulic applications that allows interchangeability between brands and simplifies system design by providing a known thread engagement and sealing approach for every connection. Swivel fittings, bulkhead adapters, 45-degree and 90-degree elbow fittings, tee and union adapters, and reducer fittings allow performance builders to route lines through tight spaces and around obstacles while maintaining correct flow area without res...
