Product Description

The IMPERIAL Low Side Gauge (SKU 422-CB, MPN 422-CB) is an analog low side compound pressure gauge designed for use with R-410A refrigerant. It features a blue color, a 2 1/2 inch diameter, and a pressure range of 14.7 psi to 500 psi, with an accuracy of ± 3-2-3%. This non-liquid filled gauge is suitable for measuring low-side pressures in HVACR systems.

Frequently Asked Questions

What is the IMPERIAL 422-CB low side gauge used for?

The IMPERIAL 422-CB low side gauge measures low-side pressure in HVACR systems using R-410A refrigerant. It is an analog compound gauge with a 2 1/2 in diameter, blue face, and a range of 14.7 psi to 500 psi, suitable for service and maintenance applications.

What are the specifications of the IMPERIAL 422-CB gauge?

The IMPERIAL 422-CB is a non-liquid filled analog low side gauge with ± 3-2-3% accuracy. It has a 2 1/2 in diameter, blue color, and a pressure range of 14.7 psi to 500 psi. It is designed specifically for R-410A refrigerant systems.

Where to buy the IMPERIAL 422-CB gauge worldwide?

3G Electric supplies the IMPERIAL 422-CB low side gauge to customers worldwide. As a global industrial solutions provider, we handle full logistics and customs clearance to deliver this gauge to your facility, regardless of location.

How to select the right low side gauge for R-410A?

For R-410A systems, select a low side gauge rated for at least 500 psi, like the IMPERIAL 422-CB. Ensure it is a compound gauge (reads vacuum to positive pressure) and matches the refrigerant type. The 2 1/2 in dial and ± 3-2-3% accuracy are standard for field service.
