VIVOHOME 1/3 HP 4 CFM 1-Stage AC Vacuum Pump & 4-Way Manifold Gauge Kit — Oil Sight, Leak-Proof Hoses

The VIVOHOME Upgraded 1/3 HP 4 CFM 1-Stage AC Vacuum Pump and 4-Way Gauge Set is a complete HVAC service kit built to evacuate, test, and recharge refrigeration and automotive air-conditioning systems.

This all-in-one kit combines a single-stage vacuum pump, a precision manifold gauge, hoses, fittings and accessories to support refrigerant evacuation, leak testing and recharging on a wide range of systems. The pump’s robust motor and one-piece housing are engineered for steady performance and reduced leakage, while the manifold and hoses deliver clear pressure readings and secure connections for accurate service work.

How effective is the pump for evacuating systems?

The pump uses a single-stage design driven by a four-pole pure-copper motor to reach and hold a deep vacuum suitable for most HVAC and refrigeration tasks. It runs at a consistent 1440 RPM for dependable suction and heat management during extended pulls. An integrated oil sight and internal backflow protection make routine use safer and simpler.

• 1/3 horsepower motor rated for steady operation
• 4 CFM flow for efficient evacuation on small to medium systems
• One-piece shell to reduce leak paths and improve durability
• Oil sight glass and backflow valve for maintenance and protection

What does the manifold gauge set include and measure?

The included 4-way manifold provides reliable, high-precision pressure readings for service tasks, enabling users to monitor both high and low sides simultaneously. Color-coded hoses and quick couplers speed up hookups and reduce confusion, while the hose locking and sealing features limit accidental rotation or leaks under pressure. The manifold works with common refrigerants when paired with the supplied adapters.

• Four-way manifold gauge with accurate high/low readings
• Color-coded hoses: red, blue, yellow and black for clear roles
• Leak-proof seals rated to high working pressures and burst resistance
• Hose locking valve for secure, stable connections

Which fittings and accessories come with the kit?

This kit arrives ready to tackle a variety of service scenarios: quick couplers, can taps, adapters for several refrigerant lines, vacuum oil, and a leak detector. Two styles of can taps and multiple adapter sizes expand compatibility with common refrigerants and line fittings found on vehicles, mini-splits and refrigeration units. A compact carrying case keeps components organized for transport and storage.

• 2 R134a quick couplers and 2 can taps (self-sealing and puncture)
• SAE adapter for 1/4" and 1/2" hoses and R410a adapters
• 330 ml bottle of vacuum oil and a leak detector for troubleshooting
• Durable carrying case and ergonomic pump handle for mobility

How compatible is this kit with different refrigerants and systems?

The set supports a broad range of refrigerants commonly used in automotive and household systems, helping technicians service multiple unit types without swapping core tools. Adapters included make it possible to connect to varying port sizes, and the durable hoses are built to withstand high pressures encountered during charging operations. Always verify refrigerant compatibility and follow safety and environmental regulations when handling refrigerants.

• Compatible with R12, R134a, R22, R502 and R410a refrigerants
• Includes adapters for common port sizes and R410a fittings
• Hoses rated for high working pressure and secure sealing
• Appropriate for vehicle HVAC, mini-splits, and refrigeration work

Who is this for: The VIVOHOME vacuum pump and gauge set is built for DIY mechanics, HVAC technicians, and maintenance professionals who need a portable, ready-to-use kit for evacuations, leak checks, and refrigerant service. It suits small-to-medium systems where a 4 CFM single-stage pump provides adequate vacuum speed, and for anyone who values organized accessories, clear pressure monitoring and broad refrigerant compatibility. For larger industrial systems or jobs requiring dual-stage deep vacuums, consider higher-capacity equipment.
