B"H This liquid filled pressure gauge measures pressure from 0-60 PSI. Ideal for hydraulic or pneumatic systems, compressors, pressure washers, and other fluid power applications. The 0-60 PSI range is a standard choice for shop air systems, air compressor outlet monitoring, and water pressure testing in residential and light commercial plumbing. Liquid filling dampens needle vibration for stable, accurate readings in high-pulsation environments.
