1.5 Inch Liquid Filled Gauge – Our gauges are very high quality gauges with very precise tolerances. These high pressure gauges will read consistently from 0-1500 PSI time and time again. They are constructed of a very clean looking stainless steel housing, and have a brass stem. The needle always moves smoothly throughout entire pressure range. This gauge is commonly used in bottle valves but it can be used anywhere an 1/8 NPT port is open! They have an easy to read white face with black marked increments! These are a great addition to any car and are easy for anyone to see!
