About these items This four-way manifold gauge set is designed for refrigerant charging and air-conditioning system testing across automotive HVAC systems, household air conditioners, and refrigeration equipment. It supports R134A, R12, R22, and R410A refrigerants, giving technicians and DIY users a flexible tool for common refrigerant service tasks. The four-valve configuration provides convenient control during charging, recovery, and system diagnostics. The set includes four 5 ft / 1.5 m refrigerant hoses constructed with four reinforced PVC layers. The hoses support pressures up to 800 PSI with a 4000 PSI burst rating. Anti-slip sealing gaskets at the hose interfaces help maintain secure connections during operation and reduce the chance of loosening or refrigerant leakage. The extended hose length also provides greater flexibility when connecting the manifold to service ports and refrigerant equipment. The gauges combine dry and liquid-filled construction with Fahrenheit temperature markings for convenient reading. Calibration screws support an accuracy class of ±1.6%, while the sight glass provides a clear view of refrigerant flow during charging. The high-pressure gauge measures from -30 to 800 PSI, while the low-pressure gauge measures from -30 to 500 PSI, allowing users to monitor different pressure conditions during HVAC service. The manifold body uses brass and aluminum 6061-T5 components for a sturdy structure and dependable sealing. The included quick couplers, adapters, valve core wrench, screwdriver, hook, gaskets, O-rings, and fittings provide a broad selection of accessories for refrigerant system connections. The organized kit helps simplify setup for routine maintenance and charging work. This AC gauge set is suitable for automotive air-conditioning service, residential HVAC maintenance, refrigeration equipment, and other compatible systems. The four-refrigerant compatibility and multiple connection accessories make it useful for technicians, mechanics, maintenance personnel, and experienced DIY users working with compatible refrigerant systems.
