SAE Flange Connectors

STAUFF Product Spotlight for February 2022

Product Spotlight

Connections with SAE Flanges in the standard pressure and high pressure series according to SAE J 518 C and ISO 6162-1/2 offer various specific advantages in numerous applications compared to tube couplings and other connection types of the same nominal size.

This is because SAE Flanges are not only suitable for high operating pressures and withstand even heavy shocks and vibrations in the hydraulic system. Particularly in larger nominal sizes, they can be installed with relatively little effort, because the required tightening torques are distributed over the four socket head screws, in contrast to tube fittings. The resulting elimination of bulky open-end spanners allows SAEFlanges to be installed in confined spaces.

SAE Flanges from STAUFF

The STAUFF Flanges product group is closely aligned with the market requirements and contains an extensive range of single-part and multi-part SAE flange connectors in the standard and high pressure series according to SAE J 518 C and ISO 6162-1/2. 

The Standard-Pressure Series (3000 PSI) contains flange components with maximum operating pressures between 35 bar and 350 bar or 508 PSI and 5075 PSI and is available for a variety of nominal sizes between DN 13 (1/2") and DN 127 (5"). 

The 6,000 PSI High-Pressure Series is suitable for maximum operating pressures up to 420 bar or 6090 PSI and covers nominal sizes between DN 13 (1/2") and DN 76 (3"), 

STAUFF SAE Flanges are used as a reliable alternative in applications where of the use of regular tube fittings is not permitted or technically not possible due to the required operating pressure, the size or the limited mounting space. 

Their biggest advantage of SAE Flanges is the considerably higher pressure resistance for most sizes and the continuous pressure level of the 6,000 PSI High-Pressure Series which can resist maximum working pressures of up to 400 bar. 

STAUFF SAE Flanges are most notably used in various fields of industry including industrial hydraulics, mobile hydraulics and shipbuilding.

SAE Flanges are supplied by STAUFF both as single components without additional accessories and as complete parts including seals made of Perbunan and metric or UNC bolt sets.

STAUFF SAE Flanges are made of steel - the exact steel quality and the surface finishing depend on the part itself and also on the chosen type of connection. Stainless steel and alternative sealing materials are also available on request.  

The STAUFF Flanges product group in completed by various types and designs of straight gear pump flanges and elbow gear pump flanges made from carbon steel and aluminium in accordance with German and Italian connection standards.
