상품 특징

• Fast Recovery and Evacuation Kit: includes 1 high-precision digital micrometer gauge (0-75000 μmHg), 1 vacuum-rated valve core removal tool (VCRT) with 1/4" 5/16" ports with brass adapter, 1 dual-head valve core removal and installer tool, 1 brass tee adapter, 1 brass dual-head adapter, 20 replacement valve cores, 1 rapid-Y connection fitting for faster evacuation and recovery (3/8" and 3/8"), 2 NHB1 high-flow refrigerant hoses-3/8" to 1/4" fittings-6 feet in length-1/2" Internal diameter
• Featuring a high-sensitivity sensor, the digital vacuum gauge delivers accurate readings from 75, 000 μmHg (atmospheric pressure) down to 0 μmHg, with ±10 μmHg/±10% precision for leak detection and evacuation quality checks; Its backlit LCD screen (0.5s refresh rate) ensures visibility in dark attics/basements, auto-shuts off after 10 minutes of inactivity, and runs on 3 AA batteries (not included) for portability; Compact design fits easily in field service kits
• Dual Calibration Modes: supports full-scale and zero calibration to maintain accuracy over time: calibrate under atmosphere by holding “SAVE/CAL” for 3 seconds, or zero-calibrate by connecting to a vacuum system (wait for 0.1 Pa, then hold “SAVE/CAL”); The gauge features a 1/4'' flare connection, supports mbar/mmHg/μmHg units, withstands up to 14 PSI, and operates from 0–50°C (32–122°F); Note: for atmospheric use only—avoid refrigerants/reactive chemical substances
• The F1028 rapid-Y fitting (solid brass, vacuum-rated to 20 microns) adds dual 3/8'' ports to vacuum pumps/recovery units, cutting evacuation time by switching from 1 to 2 hoses; Paired with NHB1 high-flow hoses (6ft, 3/8'' to 1/4'' fittings, 1/2'' internal diameter), the 4-layer construction minimizes refrigerant permeation, withstanding 3, 200 PSI burst pressure and 640 PSI working pressure for reliable performance
• Practical Combination: the valve core removal tool lets you replace leaking cores without refrigerant loss, while the 4-in-1 ratchet wrench (1/4'', 3/8'', 3/16'', 5/16'') features a curved handle for better access in tight spaces; These tools boost efficiency during routine maintenance, making them essential for daily HVAC repair tasks
