Can the Nickel-plated steel quick-connector, socket with BSP and BSPT GZ, HSP CUPLA series, NITTO KOHKI handle pulsating pressure peaks in hydraulic casting systems?

Yes. The Nickel-plated steel quick-connector, socket with BSP and BSPT GZ, HSP CUPLA series, NITTO KOHKI is designed for hydraulic power use and is manufactured from special alloy steel with nickel plating. It is explicitly characterized by excellent durability and resistance to vibrations and pulsating pressure, and is used in hydraulic systems of casting equipment where sudden pressure changes occur. With NBR sealing, an operating temperature range of -20Â°C to +80Â°C, and a working pressure up to 206 bar (size-dependent), it can handle pulsating pressure peaks typical in casting hydraulics; flow ratings are given for a 3 bar pressure drop. Operation under vacuum is also supported.
