AN to Metric Male to Male Adapters – Connect AN/JIC to Metric Ports

Connect an AN hose or fitting to a compatible metric threaded port with our aluminium AN to Metric Male to Male Adapters. Featuring a male JIC 37° flare connection at one end and an O-ring sealed male metric connection at the other, these adapters provide a compact transition between AN and metric fluid systems.

Why Choose Our AN to Metric Adapters?

AN to Metric Conversion

Provides a direct transition from a female AN/JIC fitting to a compatible metric threaded port, reducing the need for multiple adapters.
Two Purpose-Designed Sealing Methods

The AN connection seals against the mating 37° flare, while the metric connection uses an O-ring to seal against the mating port.
6061-T6 Aluminium Construction

Precision-machined from lightweight 6061-T6 aluminium and finished with a durable black anodised coating for protection against wear and corrosion.
Wide Range of Metric Threads

Available with metric threads from M10 to M22, with selected thread pitches to suit a range of compatible automotive and motorsport components.
Suitable for a Range of Fluid Systems

Ideal for adapting AN plumbing to compatible metric ports in fuel, oil and coolant systems.

How Do AN to Metric Adapters Seal?

The two connections use different sealing methods. The AN/JIC connection seals on its 37° flare, while the metric connection seals using an O-ring against the mating port. The metric thread itself is used to retain the adapter rather than providing the fluid seal.

Check the Metric Thread and Port Before Ordering

Metric thread diameter alone does not determine compatibility. Check the thread diameter, thread pitch and sealing arrangement of the mating port before selecting an adapter. These adapters are designed for compatible O-ring sealed metric ports.

Check the metric port before ordering. The thread diameter, thread pitch and sealing arrangement must all be compatible. The metric connection on these adapters is designed to seal using an O-ring.

Frequently Asked Questions

What are AN to metric male to male adapters used for?
AN to metric adapters provide a transition between a female AN/JIC fitting and a compatible metric threaded port. They are commonly used when connecting AN hose systems to components with metric connections.
How does the AN connection seal?
The male AN/JIC connection seals against the corresponding 37° flare inside a compatible female fitting. The AN thread draws the mating flare surfaces together but is not itself the primary sealing surface.
How does the metric connection seal?
The metric connection uses an O-ring to create the fluid seal against a compatible mating port. The thread secures the adapter into the port while the O-ring provides the seal.
Do I need thread sealant or PTFE tape?
No. The AN side seals on its 37° flare and the metric side seals using an O-ring, so thread sealant or PTFE tape should not be required on either connection when installed into the correct mating fittings.
How do I choose the correct metric adapter?
Check both the metric thread diameter and thread pitch of the mating port, as well as its sealing arrangement. For example, M12 x 1.00, M12 x 1.25 and M12 x 1.5 are different threads and are not interchangeable.
Are these adapters compatible with braided hoses?
Yes. The AN end can connect to a compatible female AN hose fitting used on a braided hose assembly, while the metric end connects to a compatible O-ring sealed metric port.
What are the adapters made from?
They are precision-machined from 6061-T6 aluminium and finished with a black anodised coating for protection against wear and corrosion.
