b'Best Practices:Pressure Gauge Installation and Maintenance InstallationLocationVibration and extreme ambient temperatures can affect pressure gauge accuracy.It is important to choose the right pressure gauge for the application.Choosing MaterialsBrass wetted parts are suitable for uses with air, oil, water, and other non-corrosivefluids. For corrosive fluids, stainless steel should be considered. Lead Free brassis also available on request for potable water applications. PreparationBe sure to use thread sealant pipe dope or PTFE tape thread sealant on male pipethread connections. Do not apply sealant to the first 2 pipe threads.ConnectionCaution: Tightening the gauge by the dial face will severely damage the gauge. Use an open-ended wrench on the gauge stem wrench flats to tighten the gauge. Male pipe threads should be tightened a minimum of 2-1/2 turns past hand tight.Leak TestingLeak test all connections. For air / gas systems, use non-corrosive leak test or soapyor soapy water solution. If a leak occurs (look for bubbles), gradually tighten fittinguntil leak stops.Venting the GaugeLiquid filled gauges should be installed in an upright position to avoid the liquid fromLeaking. Cut off the tip of the plug (if present) or lift the vent plug then re-seat it whenthe pressure gauge reflects a reading that is slightly off-zero. This allows the gaugeto equalize to atmospheric pressure.Operation and MaintenancePulsation and VibrationUsing the correct pressure gauge in areas where pulsation and vibration areconstant and unavoidable can be critical in order to avoid errors in reading causedby damage to the gauge. The Equalizerdry gauge is recommended for harshenvironments where leakage and discoloration are also a concern. 132'
