Bottom Connection

These gauges have a glycerin-filled dial that reduces needle flutter for precise readings in high-vibration applications reaching 2,000 psi. A 316 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 pressure.

Bottom Connection (Steel 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.
