Y-Blocks & Tee Fittings

Precision Fluid Distribution and Merging

Efficient fluid distribution is the heart of any high-performance engine. At AN Fittings NZ, our collection of Y-Blocks and Tee Fittings is engineered to provide maximum flow with minimal turbulence. Whether you are splitting a fuel feed to dual rails, merging multiple fuel pumps, or adding a sensor port to an existing line, these components offer a professional, high-flow alternative to restrictive "clamped" T-junctions.

We stock the full range of Speedflow blocks and fittings, ensuring that your fuel, oil, or coolant is distributed exactly where it’s needed without sacrificing pressure or volume.

The Right Configuration for Your Flow Requirements

Choosing between a Y-Block and a Tee fitting often depends on your space constraints and flow dynamics. Our range includes:

  • AN Y-Blocks: The preferred choice for high-volume applications like fuel pump manifolds. The "Y" design offers superior flow characteristics by reducing the "impact" of merging fluids, making them ideal for high-horsepower builds.

  • AN Tee Fittings: Available in Male-Male-Male or with Female swivel ends. These are the perfect "problem solvers" for adding a gauge, a nitrous port, or a bypass line to an existing AN setup.

  • Bulkhead Tees: Essential for neat plumbing through firewalls or panels where a fluid split is required on the other side.

  • Compact Billet Designs: Our Y-Blocks are CNC-machined from a single piece of 6061-T6 aluminum, providing a compact footprint that fits into tight engine bays while maintaining structural integrity under high pressure.

Built for New Zealand’s Most Demanding Builds

In a high-pressure fuel system, a cheap fitting is a major safety risk. That’s why our distribution blocks feature hard-anodized finishes and precision-machined 37° flare seats. From street-legal performance cars to dedicated offshore racing boats, our Y-Blocks and Tees are the trusted choice for NZ builders who demand zero leaks and maximum performance.
