Metric Fittings & Adapters

The Missing Link for Japanese & European Engineering

In the world of performance tuning, Metric threads are the global standard. From the oil galleries of a Nissan RB26 to the fuel systems of a modern BMW or Volkswagen, having the correct Metric hardware is the difference between a professional installation and a stripped thread. At AN Fittings NZ, we provide a comprehensive range of Metric fittings and adapters designed to interface perfectly with OEM ports.

Forget "making it fit"—our Metric range ensures you have the exact thread pitch and sealing surface required for a factory-level seal. Whether you are adding a sensor, replacing a factory hardline, or plumbing an aftermarket oil cooler, our Metric collection provides the structural integrity and precision New Zealand's top builders demand.

Precision Metric Hardware for Every System

Our inventory covers the full spectrum of Metric sizes, including M10, M12, M14, M16, and M18 with various thread pitches (1.0, 1.25, and 1.5). This collection includes:

  • Metric-to-Metric Joiners: Perfect for extending factory lines or connecting two Metric components without changing the system's standard.

  • Metric Port Adapters: Essential for oil pressure and temperature sensors. We stock the hard-to-find Metric adapters used in Japanese engine blocks and European steering racks.

  • Metric Banjo Bolts: Low-profile solutions for fuel rails and brake calipers. Available in single and double-bolt configurations to suit your flow requirements.

  • Sealing Technology: All our Metric adapters are designed for use with copper or aluminum crush washers or specialized O-ring seals, ensuring a 100% leak-free connection on flat-faced ports.

  • Speedflow Quality: CNC-machined from 6061-T6 aluminum, our adapters offer superior thread strength and corrosion resistance compared to mass-produced cast fittings.

Reliability for the Modern NZ Performance Scene

In high-vibration environments, using the wrong thread pitch (like forcing a 1/8" NPT into a 10mm port) is a recipe for disaster. We understand the subtle differences between a Toyota power steering thread and a Nissan oil feed. At AN Fittings NZ, we provide the technical hardware you need to ensure your "import" build is done right the first time, protecting your expensive engine and drivetrain components.
