The ISO-F flat-face type IF non-drip quick coupling socket with internal BSP thread is engineered for demanding hydraulic applications, particularly in construction machinery exposed to dynamic pressure changes. Manufactured from robust steel and enhanced with a zinc-nickel coating, it ensures exceptional durability and corrosion resistance far superior to standard zinc finishes. Its integrated safety pin provides reliable protection against accidental disconnection, while full interchangeability with ISO-F quick couplings from other brands guarantees versatile use across various systems. Designed for hydraulic oil transfer, the socket offers dependable sealing with NBR for temperatures between -25°C and +100°C, or viton for extended resistance up to +200°C. With a working pressure capacity of up to 400 bar, depending on size, and optimized flow performance measured at a 3-bar pressure drop, this coupling delivers maximum efficiency, safety, and long-term reliability in the toughest operating conditions.
