Series IB
A zinc-nickel coating provides effective corrosion protection. The QRC-IB series complies with the requirements of ISO 7241-1, series B and is thus aimed at the broad international market for standard hydraulic couplings. Series QRC-IB from DN 6 to DN 51 for operating pressures up to 500 bar (7,250 PSI) (depending on coupling size) at nominal flow rates up to 1000 l/min are available from stock. This series can be used universally in industrial and stationary hydraulics and is characterised by particularly high corrosion resistance.
