Reliable hydraulic connection system for applications up to 630bar

08 August 2015

The multi-part steel flare fittings from Stauff's Connect range are suitable for hydraulic hose connections which previously needed to be welded for safety reasons.

Comprising fitting bodies, cone adapters with O-rings, support sleeves and union nuts, flare fittings allow leak-free and pull-out proof connection of tubes with a 37° flare in line with DIN 3949, and threaded fittings with 24° cone in line with ISO 8434-1.

They are primarily used in hydraulic systems where previously complicated welding connections had to be used for safety reasons. They are suitable for rated pressure up to 500bar (Light Series) and up to 630bar (Heavy Series). Stauff connectors come with a four-fold safety margin: burst pressure is at least four times the stated rated pressure.

Features include elastomer seals that perform well when subjected to vibration and pressure fluctuations, and a high-quality zinc nickel coating for corrosion protection.
