3D Instruments 25502-21B21 GAD Pressure Gauge

The 3D Instruments 25502-21B21 GAD Pressure Gauge is a 2.5-inch dial gauge from 3D Instruments designed for metric pressure measurement in industrial systems. It features a back-mounted 1/4" NPT connection and a 0–200 kPa scale, enabling compact installation in pneumatic or hydraulic circuits where metric readings are required. The GAD suffix denotes vibration dampening, a feature intended to reduce pointer flutter in environments with pulsation or vibration. This gauge is commonly used in process control panels, test benches, and laboratory equipment where monitoring of moderate pressures in kilopascals is essential. The 2.5" dial provides legible readings in control cabinets and instrumentation housings, while the 0–200 kPa range covers typical low-to-midrange pressures encountered in compressed-air systems and low-pressure fluid circuits. Designed for compatibility with standard fittings and mounting hardware, it fits conventional panel openings and back-connection setups found in industrial environments.
