The standard quick coupling socket with internal BSP thread is a reliable solution designed for demanding hydraulic applications, particularly in agricultural machinery where efficiency and durability are essential. Manufactured from robust galvanized steel, it ensures long-lasting resistance to wear and corrosion, while the NBR sealing system guarantees secure performance in a wide temperature range from -25°C to +100°C. Engineered to operate with hydraulic oil at working pressures of up to 400 bar, depending on the coupling size, this socket delivers consistent power transmission and dependable flow rates measured at Δp = 3 bar. Unlike ISO-A and ISO-B couplings, it features unique dimensions tailored to the manufacturer’s standard, making it an excellent choice for systems requiring precise compatibility and high operational safety. Its versatility and strength make it a trusted component for professionals seeking reliable hydraulic connections in intensive field conditions.
