These gauges have a glycerin-filled dial to reduce needle flutter for precise readings in high-vibration applications. Use them to test and calibrate pressure gauges and other equipment. Gauges have a safety case that blows out in the back under excess pressure, protecting the operator in front.

Gauges with stainless steel guard provide protection from corrosive media.

Gauges with polypropylene case can handle higher temperatures than gauges with phenolic case.

Tank-Mount Pressure-Regulating
Valves for Moisture Removal

For Use With: Nitrogen
Temperature Range: 32° to 120° F

Designed for nitrogen gas purging in air conditioning, refrigeration, and plumbing systems, these valves automatically reduce a high inlet pressure from to a lower, stable outlet pressure. Use the knob to select the set pressure for testing, purging, or brazing. All have Compressed Gas Association (CGA) numbered inlet fittings for secure connections to compressed gas tanks. Choose a valve with the same CGA number as your tank and other system components. Valves have 45° flared tube outlet fittings for a tight seal on metal tubing. They come with a gauge to monitor inlet pressure from the tank. All are single stage and reduce pressure in one step, which causes the outlet pressure to fluctuate slightly as you empty the tank.

Choose a valve with a maximum outlet pressure that’s approximately twice your application’s normal operating pressure. Your operating pressure should never exceed 75% of the valve’s maximum outlet pressure.
