The 7BC-GDK/S and 7BD-GDK/S Series BSP Pressure Gauge Connectors are designed to provide secure and reliable connections between hydraulic pipelines and pressure gauges. The fittings feature a BSP male threaded connection combined with a DKI steel sealing washer, ensuring stable sealing performance without leakage during pressure monitoring.

The straight-through flow design allows unrestricted fluid passage and minimizes pressure loss, helping maintain accurate pressure readings. The sleeve-type installation structure simplifies assembly while ensuring a secure connection in high-pressure hydraulic systems.
Manufactured from premium stainless steel, these pressure gauge connectors provide excellent mechanical strength, corrosion resistance, and durability. They are suitable for continuous operation in hydraulic equipment, industrial machinery, pressure testing systems, and fluid control applications.
