On some installations, particularly where the application is filtering the removal of silt and sediment, it may be desirable to install a gauge on the outlet of the NP Series Housing to monitor the water pressure serving the equipment.

Should the filter cartridge become clogged with silt and sediment, it would result in a drop in water pressure. This would be displayed by the gauge, which is red lined for presure under 20 psi.

This gauge has a Tee connector with a 3/8" MPT inlet and a 3/8" FPT outlet.
