Metric & NPT Adapters

The Ultimate Metric-to-AN Solution

Modern performance tuning often requires marrying two different worlds: the Metric threads found on Japanese and European OEM components and the NPT/AN standards used in the performance aftermarket. At AN Fittings NZ, we specialize in the "missing link" adapters that make these installations possible.

Whether you are fitting an oil pressure sensor to a Nissan SR20, plumbing a fuel rail on a Toyota 2JZ, or upgrading the cooling system on a European build, our Metric and NPT adapters ensure a high-pressure, leak-free connection without the need for risky "re-tapping" or custom machining.

Precision Fitment for OEM Integration

Our range is curated to solve the most common fitment headaches encountered by NZ builders:

  • Metric Adapters: We stock a massive variety of Metric sizes, including M10, M12, M14, M16, and M18 with various thread pitches (1.0, 1.25, and 1.5). These are essential for power steering pumps, fuel filters, and engine block galleries.

  • NPT (National Pipe Thread): The standard tapered thread for American-made components and most aftermarket gauges and sensors. Our NPT to AN adapters allow you to jump straight into a high-flow plumbing system.

  • Crush Washer & O-Ring Sealing: Our Metric adapters are designed for professional installation, featuring the correct seating surfaces for crush washers or O-rings to ensure a 100% seal on flat-faced ports.

  • Speedflow Quality: Manufactured from 6061-T6 aluminum, our adapters offer superior thread strength and corrosion resistance compared to cheap cast alternatives.

Reliable Plumbing for Japanese & European Imports

In the world of high-performance imports, using the wrong thread pitch is a costly mistake. Our team at AN Fittings NZ understands the subtle differences between a 1/8" NPT and a 1/8" BSPT, or an M12x1.25 and an M12x1.5. We provide the technical hardware you need to ensure your build is done right the first time.
