For many years, Flanges Australia tube fittings have proved a success in a great variety of technical applications. Manufactured by Larga according to DIN EN ISO 8434-1 and DIN 2353, the geometric shape of our tube fittings is the basis for a simple, reliable, and most important of all, leak free operation of hydraulic tubes and fittings. The assembly process can either be carried out in the fitting body or in a special assembly die, although we recommend the latter. Stainless steel fittings should always be assembled in the assembly die.

When tightening the nut the cutting edges of the Flanges Australia progressive ring are moved in axial direction towards the standardised 24 degree cone.

This movement, which is exactly defined by the geometric shape, causes the cutting edges to bite into the tube surface, leading to a firm tube clamping. The right assembly can be recognised by a visible collar of cut tube material which is solidified by this cold forming process.

The cutting ring also has a stop shape which causes a considerable increase of the assembly forces, giving a clear indication to stop the assembly.

The shape of the cutting ring, the nut and the fitting body provides an excellent resistance against stress concentration, it is particularly important to point out that the cutting ring acts aa a spring as it is clamped between the nut and the fitting cone. This spring effect is an important feature to dampen vibrations which might otherwise lead to fitting leakages.
