Series IA

The coupling series QRC-IA, according to ISO 7241-1, series A is widely used in agricultural engineering. This series is characterised, among other things, by particularly high corrosion resistance. Design and performance are specified in the standard. The high safety factor of the coupling is also typical for STAUFF: The burst pressure corresponds to at least four times the operating pressure. The series is available from stock in eight sizes from DN 6 to DN 51 for operating pressures up to 450 bar (depending on the coupling size). The compact design enables use in confined machine areas. Even then, comfortable and safe operation is guaranteed: The operator only has to pull back the sliding sleeve of the coupling loose half. The plug-in couplings of the IA series made of stainless steel are ideally suited for agricultural and forestry machinery and stationary hydraulics.
