Low-Pressure Gauges for Chemicals

With PVC Guard

With CPVC Guard

With Polypropylene Guard

Bottom Connection (Plastic Guard)

A plastic or stainless steel guard, also known as an isolator, protects the gauge from damage caused by corrosive chemicals. Use them with pumps, filters, regulators, and in process lines to measure and display pressures.

Polypropylene and 316 stainless steel guards are more chemical resistant than PVC and CPVC guards.

3-in-1 Pressure and Vacuum Gauges

These portable gauges have three different dials to display pressure and vacuum measurements on a low, medium, and high scale. Also known as compound gauges, they measure both pressure and vacuum in hydraulic applications.
