Filters, Check Valves & Turbo Adapters

Critical Protection and Precision Flow Control

Beyond the hoses and fittings, a high-performance system requires components that actively manage fluid health and behavior. At AN Fittings NZ, our collection of Filters, Check Valves, and Turbo Adapters provides the essential safeguards your engine needs. From preventing fuel drain-back to protecting delicate turbo bearings from contaminants, these components are engineered for the high-pressure, high-temperature demands of modern motorsport.

Don't leave your expensive engine internals or turbocharger to chance. Our range of Speedflow and performance hardware is designed to offer maximum protection with minimal flow restriction.

Advanced Hardware for System Integrity

This collection features the "problem solvers" and "protection units" for fuel, oil, and air systems:

  • In-Line Fuel & Oil Filters: Featuring high-flow stainless steel or pleated elements. These filters are essential for protecting fuel injectors and engine bearings from microscopic debris without causing a pressure drop.

  • One-Way Check Valves: Crucial for fuel systems to prevent drain-back and ensure "instant-on" pressure. These are also used in vacuum and brake booster lines to ensure fluid or air only moves in the intended direction.

  • Turbo Oil Feed Adapters: Precision-machined fittings designed to bridge the gap between your engine block and your turbocharger. We stock the specific threads required for Garrett, BorgWarner, and Mitsubishi turbochargers.

  • Turbo Oil Restrictors: Many ball-bearing turbos require a specific, reduced oil flow to prevent seal failure. Our precision-drilled restrictors provide the exact orifice size needed for a long-lasting turbo setup.

  • Drain Flanges & Fittings: High-flow -10AN and -12AN adapters for turbo oil returns, ensuring that oil can escape the turbo housing quickly to prevent smoking or oil leaks.

Reliability for NZ’s Most Demanding Builds

Whether you are plumbing a high-boost drift car or a reliable street-legal restoration, these components are the insurance policy for your build. We source filters with cleanable elements for long-term value and valves with high-grade internal seals compatible with modern ethanol-blend fuels (E85). At AN Fittings NZ, we provide the technical hardware that keeps New Zealand’s fastest cars on the track and out of the workshop.
