The quick coupling socket with internal BSP or NPT thread (3/16″ ÷ 1″) and integrated valve is a highly versatile solution designed for demanding applications. Engineered with two O-rings and a backup ring, it ensures exceptional tightness and reliability, making it particularly effective for gas media while also performing flawlessly in hydraulic systems with hydraulic oil. Its robust construction allows safe use with water, steam, fuels, oils, and a wide range of chemicals, offering maximum flexibility across industrial environments. Fully interchangeable with ISO-B quick couplings from other manufacturers, it guarantees compatibility and ease of integration into existing systems. With a working pressure of up to 345 bar, depending on the coupling size, and a safety factor of 4:1, it delivers outstanding durability and operational security. Manufactured from galvanized carbon steel and sealed with NBR, it provides long-lasting resistance to wear and corrosion. Designed to withstand extreme conditions, it operates reliably within a temperature range from -40°C to +121°C, ensuring consistent performance even in the most challenging environments.
