The standard quick coupling plug with internal BSP thread is a reliable solution designed for demanding hydraulic applications, particularly in agricultural machinery where durability and efficiency are essential. Manufactured from high-quality galvanized steel, it ensures excellent resistance to wear and corrosion, while the NBR sealing system provides secure performance across a wide temperature range from -25°C to +100°C. With a working pressure of up to 400 bar, depending on the coupling size, this plug guarantees safe and consistent operation even under intensive conditions. Unlike ISO-A and ISO-B couplings, it features unique dimensions tailored to the manufacturer’s standard, offering a precise fit and dependable connection. Optimized for hydraulic oil systems, it delivers a stable flow rate at Δp = 3 bar, making it an ideal choice for professionals seeking robust, long-lasting, and high-performance hydraulic components.
