• 1. Complete A/C Refrigerant Recharge and Service Kit:This professional-grade manifold gauge set provides everything needed for automotive and home air conditioning system service. Perfect for evacuating, charging, and diagnosing R134a, R12, and R22 refrigerant systems. The comprehensive kit enables precise refrigerant management and system performance evaluation.
• 2. Easy-to-Install R134a Quick-Connect Fittings:Features standard 1/4" SAE quick-connect fittings that securely attach to R134a service ports on automotive A/C systems. The color-coded hoses (blue for low pressure, red for high pressure) prevent connection errors. The fittings include depressors that automatically engage when connected, allowing easy refrigerant flow.
• 3. Triple-Scale Professional Manifold Gauge:Equipped with a high-visibility manifold featuring three concentric scales: outer ring displays refrigerant charge amount in kilograms/pounds, middle ring shows system pressure in PSI/kPa, and inner ring indicates temperature correlations. The large, clear dial faces are color-zoned for normal/abnormal pressure ranges.
• 4. Dual-Hose Configuration for Complete Service:Includes two professional hoses: low-pressure side (blue, 58cm/22.8in) and high-pressure side (red, 38cm/15.0in) with proper length for accessing difficult service ports. The hoses feature 1/4"" flare fittings with built-in shut-off valves to prevent refrigerant loss during disconnection.
• 5. Wide Refrigerant Compatibility:Compatible with multiple refrigerant types including R134a (automotive standard), R12 (older automotive), and R22 (residential/commercial). The gauge calibrations accommodate different pressure characteristics of each refrigerant type, making it a versatile tool for various A/C systems.
