Durable Metal Construction

The AC gauge set features solid brass fittings and an aluminum valve body for durability and reliable sealing. Each part has been tested for repeated operation both in laboratory environments and on-site locations.

High-Pressure Sealing Hoses

The 4 hoses made of durable rubber, each 5 ft (1.5 m) long, are designed for a working pressure of 800-4000 PSI. Flanged and brass connections help reduce leakage and prevent loosening during service.

Clear Dual Scale Indicators

The AC gauges feature colorful high and low pressure indicators for easy reading. Calibration screws maintain ±1% accuracy, while temperature scales in Fahrenheit and the viewing window assist in estimating the charge level during testing.

Compatible with Four Refrigerants

This 4-way gauge supports pressure testing for R22, R404A, R410A, and R12. It is specially designed for home central air conditioning units and commercial refrigeration equipment.
