The NITTO KOHKI HSP CUPLA quick coupling socket with internal BSPT thread is a high-performance solution designed for demanding hydraulic applications. Manufactured in Japan from premium nickel-plated alloy steel, it ensures exceptional strength, long-lasting durability, and reliable resistance to vibrations as well as pulsating pressure. Engineered to perform even under sudden pressure fluctuations, it is ideally suited for use in hydraulic systems of casting equipment and other heavy-duty machinery. The coupling is compatible with hydraulic oil, features NBR sealing for secure and leak-free operation, and maintains efficiency across a wide temperature range from -20°C to +80°C. With a working pressure capacity of up to 206 bar, depending on the size, and optimized flow performance calculated at a 3 bar pressure drop, this coupling guarantees stability and safety in critical processes. Its ability to operate under vacuum further expands its versatility, making it a trusted choice for industries that demand precision, reliability, and consistent performance in challenging environments.
