Pressure Gauges are inexpensive and if selected and installed correctly can give years of trouble free use.

Before fitting the gauge to a pressure source check that the maximum scale value of the gauge is higher than the pressure applied. The applied pressure should be 75% of the max scale value for steady pressures or 65% of max scale value for fluctuating pressures.

Before fitting the gauge to a pressure source check that the wetted parts are compatible with the fluid being used, and that the pressure connection correctly matches that of the pipework. When fitting the gauge to the pipework, use a correct sealing methods.

Do not use the gauge case to tighten the gauge to the pipework, use a correct size spanner on the neck of hexagon.

Pressure Gauges with blow-out release at the back must be mounted at least 20 mm away from a panel or wall to ensure safe dissipation of the confined pressure should the tube fracture.

Gauges marked 'Hydraulic' must not be used on compressed gases.

Gauges must have 'Oxygen' or 'Acetylene' marked on the dial if used on these gases.
