The Holmbury quick coupling socket with Nordic interchange is engineered for demanding applications, combining durability with advanced safety features. Equipped with an integrated shut-off valve and internal BSP thread, it ensures secure and efficient operation even under high residual pressure, thanks to the built-in pressure eliminator that simplifies connection. Manufactured from robust steel with a high-performance zinc-nickel coating, the socket delivers long-lasting resistance to wear and corrosion, making it a reliable choice for both industrial and hydraulic power systems. Its additional O-ring enhances sealing performance, making it suitable for gas installations, while the safety ring prevents accidental disconnection, ensuring uninterrupted workflow. Designed for working pressures up to 350 bar, with a 4:1 safety factor, the coupling guarantees dependable performance in heavy-duty environments. The NBR rubber sealing provides excellent resistance across a wide temperature range from -25°C to +100°C, ensuring consistent functionality in varying conditions. Optimized for hydraulic oil and general industrial use, the socket offers efficient flow characteristics with pressure drop values specified at 3 bar, making it a versatile and secure solution for professional applications.
