Ashcroft 4-1/2" Type 2071A, Contractor gauges, are constructed with a back flanged aluminum case, painted black, and a chrome ring with a glass window.

These gauges are designed to meet the needs of heating, ventilating, plumbing and air conditioning contractors. The accuracy of these gauges is ASME B40.100, Grade A, ±2-1-2%. 

Incorporated in Type 2071A gauges is the PowerFlex movement. This movement provides superior resistance to shock, vibration, and pulsation; thereby assuring longer life for your pressure instrument.
