R454B AC Manifold Gauge Set for R454B R32 R410A, 3 Valve Refrigerant Charging Gauges with Three 60 in Hoses and Adapters for HVAC Service

The HONGSEN A2L Manifold Gauge Set is designed for servicing modern air conditioning and heat pump systems using R454B, R32, and R410A refrigerants. Built for residential and light commercial HVAC applications, this set supports refrigerant charging, evacuation, pressure testing, and routine maintenance work. The classic three-valve manifold layout allows independent control of high and low pressure sides, providing stable refrigerant flow management during system service. The analog gauges feature dual pressure units (PSI and bar) with refrigerant-specific scales for clear and practical field readings. This kit includes three color-coded charging hoses measuring 60 in (1.5 m) each, offering flexible reach when working around outdoor condensers or in tight mechanical areas. Adapters are included to support compatibility with A2L refrigerant systems. Constructed with brass and aluminum components and protected by rubber gauge boots, the manifold body is designed for repeated HVAC service use. Suitable for technicians working with modern A2L-compatible refrigeration systems.
