A four-valve manifold gauge set for R134A, R12, R22 and R410A work, aimed at DIY car AC, home air-conditioning and refrigerator service. It ships with four 5 ft PVC hoses rated to 800 psi working and 4000 psi burst, quick couplers, three adapters, a valve core wrench and a can tap. The dry dial with calibration screws and a sight glass is a practical step up from basic two-valve sets, though the brass body and four hoses make it heavier to hang. It suits home mechanics and light HVAC work more than daily professional use.

This four-way manifold gauge set is for servicing refrigerant systems. It works with R134A, R22, R12 and R410A refrigerants. It can be used for automotive HVAC, household air conditioning and refrigerator maintenance, including charging, evacuation, recovery and filling.
The gauge combines a dry and liquid-filled design, with a dry dial to improve winter performance. Calibration screws keep accuracy at ±1.6%. Temperature is read in Fahrenheit, and a sight glass shows liquid refrigerant flowing during filling.
The set comes with four 5-foot PVC hoses with four reinforced layers. Anti-slip sealing gaskets at the hose connections help prevent loosening and leaks. The body is made of solid brass, aluminum, PVC and plastic.
