VIVOHOME AC Vacuum Pump Kit 1/3 HP 5 CFM — Single-Stage Pump with 4-Way Manifold & Hoses

VIVOHOME's upgraded HVAC kit combines a 1/3 HP, 5 CFM single-stage vacuum pump with a four-way manifold gauge set and accessory pack for evacuating, testing, and recharging air conditioning and refrigeration systems.

This all-in-one service kit gathers the core tools technicians and savvy DIYers need to perform refrigerant evacuation, leak checks, and charging across a wide range of systems. The set pairs a durable vacuum pump featuring a pure-copper motor and one-piece shell with a precision manifold and reinforced hoses, plus adapters and accessories to handle common refrigerants including R134a and R410a.

How does the vacuum pump perform for HVAC tasks?

The vacuum pump delivers steady suction with a 1/3 HP motor running at 2880 RPM, capable of pulling an ultimate vacuum down to about 37.5 microns. Its one-piece housing reduces external leaks and the sight glass on the oil reservoir makes fluid monitoring straightforward.

• 5 CFM flow rate suitable for automotive and small to medium residential systems
• Pure copper motor for thermal stability and consistent RPM
• Oil sight glass (250–360 ml) for easy level checks
• Inner backflow valve and mesh vent for protection and cooling

What does the manifold gauge and hose set include and measure?

The included four-way manifold provides accurate high and low side readings and features a hose locking valve for extra leak protection during service. The four color-coded hoses use multi-layer construction and robust seals that stand up to a wide pressure range.

• Four-color hoses with leak-proof seals and 4-layer build
• Hose pressure tolerance roughly 800–4000 psi depending on line and condition
• Hose locking valve for secure connections while charging or evacuating
• Clear, readable gauges for routine diagnostics and system monitoring

Which refrigerants and systems are compatible with this kit?

The kit ships with SAE adapters and two R410A adapters to support multiple service scenarios. Compatibility includes legacy and modern refrigerants, making it suitable for vehicle AC work, household refrigeration, mini-split systems and many light-commercial jobs.

• Works with R12, R134a, R22, R502, and R410a with included adapters
• SAE fittings for 1/4" and 1/2" hoses plus 1/4" to 5/16" R410a adapter
• Two quick-coupler R134a fittings and two can taps for refrigerant cans
• Leak detector included for basic leak troubleshooting

How easy is it to transport, set up, and maintain?

The pump and accessories are organized in a portable case with an ergonomic handle to simplify carrying between jobs. Routine maintenance is approachable: monitor oil through the sight glass and use the mesh vent to keep the motor cool during continuous operation.

• Carrying case and ergonomic handle for on-the-go service calls
• Oil sight glass simplifies oil level checks and routine service
• Backflow prevention reduces the chance of liquid return to the pump
• Mesh vent improves heat dissipation during extended use

Who is this for: This VIVOHOME kit is built for independent HVAC technicians, automotive AC specialists, and experienced DIYers who need a compact, versatile service set. It suits maintenance and repair on small- to medium-capacity systems where reliable vacuum, clear diagnostics, and flexible refrigerant compatibility are required. If you perform occasional to frequent AC evacuation, leak testing, and charging and want a single kit that covers multiple refrigerants and adapters, this toolset is aimed at you.
