Digital Vacuum Gauge Kit 0-75000 μmHg for HVAC, Valve Core Removal Tool with Repair Wrench Set 3/8" 1/4" 5/16" 3/16", Y Connection Fitting & Nhb1 High-Flow Refrigerant Hose & Adapters

Features: Streamline your evacuation process Time is money for HVAC technicians, vacuum gauge kit is designed to optimize your workflow. By combining a precise digital micrometer gauge with a valve core removal tool (VCRT), you can remove restrictions in the line to pull a vacuum faster while monitoring the depth in real time. No need to switch between different tools or guess if the system is dry. The brass tee allows for a seamless setup, letting you connect your micrometer pump and gauge simultaneously, whether you are diagnosing a leak in a car ac or installing a mini split, this kit ensures you reach the target vacuum level with confidence Lab grade with durability Stop relying on gauges that can't read deep vacuums. Moisture and non condensables are the enemies of refrigeration systems, and the only way to ensure they are gone is by measuring in micrometer. Digital gauge provides the resolution (1 micrometer) needed to verify a tight, dry system. Paired with robust brass adapters that resist corrosion and wear Specifications: Material: various materials such as brass Color: black, gold, silver, etc. Size: multiple sizes Package includes: 1 x Digital vacuum gauge with power adapter 1 x Vacuum rated valve core removal installer tool 1/4'' and 5/16" 1 x Dual head valve core removal installer tool 1 x Brass tee adapter 1 x Brass dual head adapter 1 x 2 -way hose splitter for HVAC - 2 x 3/8″ to 1 x 3/8″ 2 x NHB1 high-flow refrigerant hose(20 Microns Vacuum) 2 x HVAC service wrenches with 2 hex bit adapters 20 x Valve cores 1 x Portable tool bag 1 x User manual Notes: Manual measurement, please allow slight errors on size.

• 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
