VIVOHOME 1/3 HP 5 CFM Vacuum Pump with 4-Way Manifold Gauge Set — 37.5 Micron Ultimate Vacuum, R410a/SAE Adapters

The VIVOHOME upgraded HVAC kit combines a 1/3 HP, 5 CFM single-stage vacuum pump with a 4-way manifold gauge set and accessories for professional-grade refrigerant evacuation and charging.

This all-in-one toolkit is built to help technicians and DIYers evacuate, test, and recharge air conditioning and refrigeration systems. The package pairs a robust vacuum pump—featuring a copper motor and a one-piece shell—with an accurate 4-way manifold, color-coded hoses, couplers, can taps, oil, and adapters for common refrigerants. The components are engineered for durability, leak resistance, and easier system servicing across automotive, residential, and commercial HVAC tasks.

How does this vacuum pump perform for evacuation tasks?

The 1/3 HP pump uses a pure copper 2880 RPM motor and a one-piece outer shell to deliver stable suction and improved leak resistance. It reaches an ultimate vacuum down to approximately 37.5 microns, suitable for thorough moisture removal before charging refrigerant.

• 5 CFM flow rate for efficient evacuation of small-to-medium systems
• 37.5 microns ultimate vacuum for deep dehydration of lines and components
• Mesh vent and backflow valve for heat dissipation and liquid prevention
• Oil sight glass (250–360 ml) to monitor pump lubrication levels

What features come with the 4-way manifold and hose set?

The included manifold gauge provides precise pressure readings and system control with four color-coded hoses for safe, organized connections. Hoses have leak-proof seals and a multi-layer construction designed to resist higher pressures and wear during repeated service cycles.

• Four-way manifold for monitoring multiple ports and service operations
• Color-coded hoses with 4-layer build and leak-proof fittings
• Hose locking valves for secondary leak protection under pressure
• Adapters for R410a and SAE fittings to connect a wide range of systems

Which refrigerants and systems is this kit compatible with?

This kit is configured to work with many common refrigerants used in automotive and light commercial/residential systems. Included SAE adapters and dedicated R410a fittings broaden compatibility so you can service vehicles, mini-splits, refrigerators, and other cooling equipment.

• Compatible with R12, R134a, R22, R502, and R410a when using proper adapters
• Includes two R134a couplers and two can taps for quick recharging
• SAE adapters for both 1/4" and 1/2" fittings plus 1/4" to 5/16" R410a adapters
• Suitable for vehicle HVAC, residential refrigeration, and mini-split servicing

What ergonomic and durability details improve day-to-day use?

The pump and accessories emphasize portability, monitoring, and protection during repeated use. Practical touches reduce setup time and help preserve component life under routine field conditions.

• Ergonomic handle and molded carrying case for easy transport and storage
• One-piece shell resists external leaks and improves structural durability
• Inner backflow valve to prevent liquid from entering the motor chamber
• Comes with 0.35 qt / 330 ml pump oil to get started right away

Who is this for: The VIVOHOME upgraded 1/3 HP 5 CFM vacuum pump and 4-way gauge set is aimed at technicians, HVAC contractors, and experienced DIY owners who need a portable, multipurpose service kit. It’s suited for those who work on cars, small commercial refrigeration, residential AC units, and mini-split systems and who require reliable evacuation, accurate manifold readings, and versatile adapter options. If you need a compact, ready-to-use toolset for routine vacuuming, leak-checking, and refrigerant charging, this kit provides the components and compatibility to handle a broad range of service tasks.
