Series HUS made out of Carbon Steel

Stauff has added the QRC-HUS plug-in coupling series to its range especially for the Scandinavian markets. The design of these plug-in couplings is also referred to as "Nordic design". It features a particularly robust design, increased sealing action and particularly efficient corrosion protection. The Scandinavian industry often uses "Nordic design" couplings for this task. They differ from other coupling series due to the especially robust design which focuses on maximum service life even under adverse ambient conditions as well as increased sealing action. It is available in the nominal sizes DN10 to DN25 and is suitable for operating pressures up to 350 bar, depending on size. As usual for Stauff and particularly appropriate for this robust coupling, the QRC-HUS has a high safety factor: The bursting pressure is four times the maximum operating pressure. The high-quality zinc-nickel coating also suits the characteristics profile – it ensures long-lasting corrosion protection and offers maximum resistance to red rust/base metal corrosion.
