Stainless Steel DN5 Plug & Socket with Male Thread, Series 21KA

The quick coupling plug with Eurostandard DN5 (MINI) valve socket, series 21KA with external lBSP thread, is a high-performance solution designed for demanding industrial applications where compact size, maximum flow efficiency, and minimal pressure loss are essential. Engineered for convenient one-handed operation, it ensures a flow rate of 560 l/min for air at 6 bar with a pressure drop of only 0.5 bar, and 8 l/min for water at Δp=1 bar (Kv=0.48). With a robust working pressure of up to 35 bar, this coupling guarantees reliability even in intensive use. Manufactured from premium AISI 316Ti stainless steel for the main components and AISI 420 steel for the locking balls, it delivers outstanding durability and resistance to wear and corrosion. The viton sealing system provides excellent chemical resistance and ensures leak-free performance, while the wide operating temperature range from -15°C to +200°C makes it suitable for diverse environments. Compact yet powerful, this coupling is the ideal choice for industries seeking efficiency, safety, and long-lasting performance in fluid and air transfer systems.
