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 (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.

Universal plug-in couplings with cone valve

QRC-IB series can be used universally in industrial and stationary hydraulics.

Stauff adds the revised QRC-IB series to its range of plug-in couplings for quick connecting and releasing of hydraulic lines. This series can be used universally in industrial and stationary hydraulics and features particularly high corrosion resistance, among other things.

The QRC-IB series complies with the requirements of ISO 7241/Series B, targeting the broad international market of standard hydraulic couplings. These couplings – where design and performance are defined by a standard – are widely used, especially in the aftermarket and replacement sectors. 

With this series, Stauff demonstrates that distinctions can be made even on standardised couplings, for example with regard to service life under difficult ambient conditions. The revised series of these plug-in couplings is extraordinarily corrosion-resistant. It uses a zinc-nickel-based corrosion protection coating, which Stauff chose after intensive trials and comparative tests.

The coating offers maximum resistance to red rust/base metal corrosion in practical application and exceeds even the highest requirements of corrosion protection class K5, which are defined in VDMA standards sheet 24576 for tube connections. The high ductility of the coating is the prerequisite for the above-average wear protection under high mechanical strain. 

The QRC-IB series is available from stock in eight sizes from DN 6 to DN 51 for operating pressures up to 500 bar (depending on coupling size) at rated flows up to 1000 l/min. The range also includes stainless steel and brass versions.
