High-Pressure Differential Gauges
These gauges are able to withstand line pressures up to 3,000 psi. They are commonly used to measure pressure differences in pumps and filters.
Gauges with 316 stainless steel case are more corrosion resistant than gauges with an aluminum case.

Compact Compressed Air Regulators
A lower profile than our other compressed air regulators makes these regulators a better fit in tight spots. Use them to adjust and maintain the pressure of your compressed air. Install in your air line after filters.
Relieving regulators exhaust when the downstream pressure exceeds the set pressure. Panel-mount regulators have inlet ports on the bottom to easily connect air lines after mounting to your control panel.

Easy-Set Precision Compressed Air Regulators
A pressure-calibrated dial allows for easy adjustments to outlet pressure in high-flow applications. With an accuracy of ±0.5 psi, these regulators are good for sensitive applications where constant, consistent pressure is important. All are relieving regulators, so they exhaust when the downstream pressure exceeds the set pressure. Install in your air line after filters.
Mounting brackets (sold separately) allow you to attach the regulator to a wall or equipment.
