STAUFF Flanges

STAUFF Flanges offer a complete range of 4‑hole SAE flange connectors in steel and stainless steel. They ensure reliable, leak‑free hydraulic connections and include options for hydraulic pumps with diagonal or parallel mounting patterns, along with matching bolts, lock washers, and seals.

The product group includes single‑ and multi‑part flanges for both the 3000 PSI Standard‑Pressure Series and the 6000 PSI High‑Pressure Series. STAUFF SAE flanges are used where conventional tube fittings are unsuitable due to pressure demands, size, or limited installation space, offering notably higher pressure resistance. Flanges are available as individual parts or complete kits with Perbunan seals and metric or UNC bolt sets, with stainless steel and alternative sealing materials available on request. The range is complemented by straight and elbow gear pump flanges made from carbon steel or aluminum according to German and Italian standards.
