AC Performance - M14x1.5 to -6 AN Flare Adapter, Aluminium, Black

What it is

This is an AC Performance adapter that converts a -6 AN flare fitting to a metric M14x1.5 male thread. It’s a straight fitting designed for hose and pipe connections where both metric and AN threading are required.

What it solves

For builders and hobbyists working with hydraulic lines, fuel lines or oil lines, this adapter allows you to join components with different thread standards without modifying parts. On the paper, it promises a neat, reliable join between metric hardware and -6 AN flare systems.

Build quality and materials

The adapter is CNC machined from 6061 T-6 billet aluminium and finished with black anodising. This combination aims to strike a balance between lightness and strength, with a durable surface that resists corrosion in typical workshop environments.

In use: what you’ll notice

If you prioritise a compact, straight connection, this part can simplify routing and assembly where space is tight. The hex head helps with common tooling, and the black finish keeps things looking tidy in engine bays or under-vehicle installations. It’s not a universal fix for every configuration, so you’ll want to check exact thread compatibility in your build.

Who it’s for

This adapter suits automotive, motorsport, or DIY projects where you need to bridge -6 AN flare components to metric M14x1.5 fittings. It’s most useful when you already have metric and AN components that you want to connect without adapters that add length or complexity.

When it may not be the best option

If your system requires higher performance in extreme pressures or temperatures, or if you need a corrosion-resistant option beyond standard black anodising, you might want to review alternative materials or finishes. Also, if the exact compatibility with your components isn’t clear, double-check thread pitch and seating to avoid leaks.

Practical considerations before buying

• Confirm that you need a straight M14x1.5 to -6 AN flare connection.
• Measure available clearance to ensure the adapter won’t cause interference with nearby components.
• Check that the AN and metric components you’re pairing are compatible in both thread type and seating.

Quick comparison context

This kind of adapter sits between basic metric-to-metric joins and more specialised adaptors. If you’re aiming for a tidy, durable solution without extra fittings, and the materials meet your project’s needs, it’s a sensible option. If you require a higher-grade finish, or a different alloy, you might explore alternatives with different finishes or strength ratings.

Is it worth it?

When it makes sense

If you need a dedicated, straight adapter to connect -6 AN flare components to M14x1.5 male metric threads in a lightweight, durable package.

When it may not

If your setup demands a higher-duty material or a more corrosion-resistant coating, or if thread compatibility isn’t clearly established for your exact parts.

FAQ

• What material is it made from? 6061 T-6 billet aluminium.
• What finish does it have? Black anodised for durability.
• What threads are involved? -6 AN flare to M14x1.5 metric male threads.

Final thoughts

For projects where space and weight matter and you already work with both metric and AN fittings, this adapter offers a straightforward bridging solution in aluminium. It’s pragmatic rather than flashy, with a finish designed to hold up in typical workshop environments.

The decision moment

• You should buy it if you need a compact, straight bridge between -6 AN flare and M14x1.5 metric threads and the materials align with your use case.
• You should not buy it if you require a more heavy-duty or corrosion-resistant option, or if you’re unsure about exact thread compatibility.
