The NITTO KOHKI HSP CUPLA quick coupling plug with external BSP or 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 under challenging conditions, it is ideally suited for hydraulic systems in casting equipment, where sudden pressure fluctuations are common, and can also operate effectively under vacuum. Equipped with NBR sealing, it guarantees secure and leak-free connections, while its wide operating temperature range from -20°C to +80°C allows for versatile use in diverse environments. With a working pressure of up to 206 bar, depending on the coupling size, and optimized flow parameters calculated for a 3 bar pressure drop, this coupling plug delivers consistent efficiency and safety. Designed for hydraulic power transmission with hydraulic oil, it combines Japanese precision with advanced material technology, making it a trusted choice for industries requiring maximum reliability and performance.
