B"H This liquid filled pressure gauge measures pressure from 0-160 PSI. Ideal for hydraulic or pneumatic systems, compressors, pressure washers, and other fluid power applications. The 0-160 PSI range is frequently used on high-pressure air compressors, pressure washers, and industrial pneumatic systems that operate above standard shop air pressure. Liquid filling dampens needle vibration for stable, accurate readings in high-pulsation environments.
