VEVOR Vacuum Pump & Manifold Gauge Kit — 4.5 CFM Single-Stage with Leak Detector

VEVOR's single-stage 4.5 CFM vacuum pump and manifold gauge kit is a complete HVAC service package designed to evacuate, diagnose, and recharge refrigerant systems with professional-grade accuracy and durable components.

This all-in-one set combines a compact yet powerful rotary vane vacuum pump with a precision manifold gauge, color-coded service hoses, leak detector, adapters and accessories so you can maintain automotive A/C, residential HVAC, refrigeration, and light industrial systems. Built to work with common refrigerants including R134a, R22, R12, R502, R410A, R404A, and R407C, the kit is supplied with vacuum oil and fittings needed to start jobs right away and reduce trips to the parts counter.

How fast and deep does the vacuum pump evacuate a system?

The single-stage rotary vane pump delivers competitive flow for its size and reaches a deep vacuum level suitable for service and repair tasks. Its robust motor and oil reservoir help sustain steady vacuum performance during evacuation.

• Rated flow: 4.5 CFM (cubic feet per minute)
• Ultimate vacuum: down to around 5 Pa for thorough dehydration
• Oil capacity: approximately 0.27 qt (260 ml) for consistent lubrication
• Durable pure-copper motor construction for reliable operation

What accuracy and features does the manifold gauge offer?

The upgraded PRO manifold gauge provides precise pressure readings and enhanced durability for everyday HVAC troubleshooting. Large viewing glass and a tight accuracy tolerance let you monitor system pressures and make controlled adjustments during charging or recovery.

• Accuracy: ±1.6% for dependable measurement
• Heavy-duty construction with improved pressure resistance
• Clear dial layout for quick interpretation of low and high-side values
• Integrated valves to control flow between hoses and service ports

What connections, hoses and refrigerants are supported?

The kit includes a full complement of adapters and color-coded hoses to fit most common service applications, making it easy to hook up to different vehicle or HVAC fittings. Color coding keeps low, high and service lines identifiable during charging and vacuuming.

• Three 3.94 ft (1200 mm) hoses in red, blue and yellow for clear identification
• Working pressure range suitable for demanding jobs (800–4000 PSI ratings on components)
• Includes R410A adapter, R134a quick couplers, can taps and SAE/ACME adapter
• Compatible with R134a, R12, R22, R502, R410A, R404A, R407C refrigerants

What accessories come in the kit and how do they help on a job site?

The kit supplies everything necessary for common evacuation, leak detection and recharge steps so technicians can work without hunting for add-ons. Included tools and a carrying bag keep components organized and transportable between service locations.

• Leak detector hose to identify escapes quickly
• 0.35 qt (330 ml) bottle of vacuum oil for immediate use
• Two can taps and multiple adapters for refrigerant access and bottle connection
• Sturdy carrying bag for protection and mobility

Who is this for? This VEVOR kit is aimed at mechanics, HVAC technicians, refrigeration service providers, and competent DIYers who need a portable, capable vacuum pump and gauge set for evacuation, pressure diagnosis, and refrigerant handling. It suits routine A/C service, system maintenance and smaller refrigeration or HVAC projects where a compact, ready-to-use toolset saves time and reduces trips for parts.
