The ISO-F flat-face type IF non-drip quick coupling with internal BSP thread is engineered for demanding hydraulic applications, particularly in construction machinery exposed to significant pressure fluctuations. Manufactured from high-quality steel and enhanced with a durable zinc-nickel coating, it ensures corrosion resistance several times higher than standard zinc finishes, extending service life even in harsh environments. Fully interchangeable with ISO-F quick couplings from other leading brands, it offers flexibility and compatibility across various systems. Designed for hydraulic oil transfer, it features reliable sealing options: NBR for temperatures ranging from -25°C to +100°C and Viton for extreme conditions up to +200°C. With a working pressure capacity of up to 400 bar, depending on coupling size, and optimized flow performance at Δp = 3 bar, this coupling guarantees efficiency, safety, and long-lasting reliability in intensive hydraulic operations.
