Product Description
2BC-WD and 2BD-WD series hydraulic fittings are designed with BSP thread and captive seal (bonded sealing washer) structure, providing reliable and leak-resistant connections for hydraulic systems. The captive seal is integrated into the fitting end, eliminating the need for separate sealing washers during installation and reducing the risk of missing or incorrectly installed seals.
These BSP threaded fittings are available in straight and elbow configurations, offering flexible solutions for different hydraulic piping layouts. The compact design ensures easy installation and maintenance while maintaining stable sealing performance under high-pressure working conditions.
Manufactured from high-quality carbon steel or stainless steel materials, these fittings can be supplied with corrosion-resistant surface treatments such as zinc plating. They are suitable for hydraulic oil, water, and other industrial fluid applications where secure threaded connections and long service life are required.
