Screw-type couplings of the HS series are coupled by simply screwing the carrier and probe halves together until the thread contacts the limit stop. The coupling is designed to open both valves "en bloc" in this position.

For this reason, and due to their rugged design, they are particularly well suited for heavy-duty service conditions in construction machinery. The range of operating pressures of this series is higher than that of the HP series.

Screw-type couplings of the HS series can be coupled on both sides under pressures of up to 50 bar. The self-locking connection thread prevents any disengagement of the screw connection caused by vibrations. The screw sleeve of the probe, when correctly locked, must cover the black brake ring of the carrier.

Our well-balanced range of products offers a wide spectrum of couplings for hydraulic systems for construction equipment and vehicles as well as for agricultural machinery. Owing to the modular design, a large variety of connections conforming to international standards is available.
