Connect AN Fittings Directly to Hardline Tube

These AN female to hardline tube adapters provide a direct transition between a male AN fitting and rigid hardline without requiring the tube to be flared. They are suitable for aluminium, stainless steel and copper hardline.

Brass Compression Olive Connection

The hardline is secured using a brass compression olive. Insert the correctly sized tube into the adapter and tighten the compression assembly to form the connection, without using a conventional tube nut, sleeve and flared tube end.

The stated hardline size refers to the outside diameter (OD) of the tube.

Swivel Female AN Connection

The female AN connection swivels independently, allowing it to be tightened without rotating the adjoining component. It uses a JIC 37° female cone flare for connection to a compatible male AN fitting.

6061-T6 Aluminium Construction

The adapter body is manufactured from 6061-T6 aluminium with a black anodised finish. The adapter can be reused if it remains undamaged, but a new compression olive should be fitted whenever the hardline connection is reassembled.

Frequently Asked Questions

Does the hardline need to be flared?
No. The hardline connection uses a brass compression olive, so the end of the tube does not need to be flared.
Are the hardline sizes inside or outside diameter?
The listed hardline sizes refer to the outside diameter (OD) of the tube. Select the adapter to match the outside diameter of your hardline.
What hardline materials can I use?
These adapters are suitable for aluminium, stainless steel and copper hardline in the corresponding outside diameter.
How does the AN connection seal?
The female AN connection seals against the mating male fitting on the JIC 37° flare surfaces rather than on the threads.
Can the adapter be reused?
The adapter can be reused if it remains undamaged. A new compression olive should be fitted whenever the hardline connection is reassembled.
