Series IA (Carbon Steel)

The plug-in couplings as per ISO 7241/series 1 are the most important reference couplings in agricultural engineering. The QRC-IA series is exceptionally resistant to corrosion.  The high safety factor of the coupling is also typical for Stauff: The burst pressure is 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 350 bar (depending on coupling size). The compact design allows use in tight machine spaces. Convenient and reliable operation is ensured even then: The operator only has to pull back the sliding sleeve of the loose coupling half. The series IA is particularly suitable for agricultural and forestry machines.
