STAUFF Flanges


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 400 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.

Compared to tube fittings, the biggest advantage of SAE Flanges is the considerably higher-pressure resistance for most sizes and the continuous pressure level in the High-Pressure Series (6000 PSI).
