The universal quick-connect plug with valve DN5.8 and internal BSP thread is a reliable solution designed in accordance with the TEMA 1300N standard, widely recognized in the Scandinavian market. Engineered for use with liquids such as water, steam, oils, and fuels, it ensures maximum safety by preventing leaks during disconnection thanks to its double shut-off system. Compact in size yet offering high flow capacity, it combines functionality with durability. Manufactured from nickel- and chrome-plated brass or robust AISI 316 stainless steel, it guarantees excellent resistance to corrosion even in demanding environments. With performance values of 13.5 l/min for water (Δp = 1 bar, Kv = 0.81) and up to 760 l/min for air (Pe = 6 bar, Δp = 0.5 bar), it delivers efficiency across a wide range of applications. The coupling withstands working pressures up to 50 bar (10 bar for steam) and offers reliable sealing with NBR or Viton, covering operating temperatures from -20°C to +100°C (NBR) and -25°C to +200°C (Viton). This makes it an ideal choice for industries requiring secure, leak-free, and long-lasting connections in fluid handling systems.
