VIVOHOME 1/3 HP 4 CFM Vacuum Pump & R134a Manifold Gauge Kit — Portable, 3 Hoses

The VIVOHOME 1/3 HP 4 CFM single-stage vacuum pump paired with a professional R134a manifold gauge set is a portable all-in-one kit for evacuating, testing and servicing automotive and residential A/C systems.

This kit combines a robust 4 CFM rotary vane vacuum pump with a shock-resistant manifold gauge set and accessories to help remove moisture, verify pressures, and charge refrigerant on a wide range of systems. Built for occasional DIYers and trade professionals alike, the set balances performance and portability: a die-cast aluminum pump housing, sight glass and drain port for clean oil maintenance, three reinforced color-coded hoses, and essential adapters for common refrigerants including R134a and R410a.

How fast and deep can the pump evacuate an A/C system?

The single-stage 4 CFM pump delivers quick evacuation suitable for automotive A/C and smaller residential split, window, or portable units. It reaches service-level vacuum much faster than smaller hobby pumps, reducing downtime and improving refrigerant charging accuracy.

• 4 CFM displacement for rapid air removal
• Rotary vane single-stage design for reliable deep vacuum
• Clear oil sight glass to monitor pump health
• Bottom drain port for mess-free oil changes

What features help the pump run continuously and stay accurate?

The pump includes a high-volume cooling fan to support extended operation without overheating, while the die-cast aluminum body and anti-slip base add durability and stability during use. The manifold gauges use shock-resistant components and large viewing windows for repeatable, easy-to-read pressure measurements.

• Built-in cooling fan for sustained run times
• Anti-slip base reduces vibration and movement
• Shock-resistant gauge cores maintain calibration during transport
• Large gauge faces and viewing glass for clear readings

Which refrigerants and connections does the kit support?

The manifold and hoses are compatible with common refrigerants including R134a, R12, R22, R502 and, with the included adapter, R410a. Three 5-foot reinforced hoses with color coding (red/high, blue/low, yellow/service) make hookups straightforward and help prevent cross-connection mistakes.

• Includes 1/4"-to-5/16" adapter for R410a compatibility
• Three reinforced 5 ft hoses for flexible reach
• Color-coded hoses reduce setup errors
• Quick couplers and can taps included for common service tasks

What comes in the complete accessory kit and how portable is it?

The package supplies the vacuum pump, manifold gauge set, three hoses, leak detector, R410a adapters, R134a can taps, quick couplers, pump oil (0.35 qt/330 ml) and a carry bag to keep everything organized. The pump’s ergonomic handle and lightweight footprint make the set easy to transport between vehicles or job sites.

• All-in-one carry bag for tidy storage and transport
• Included pump oil and drain port simplify maintenance
• Leak detector and can taps expand diagnostic capability
• Ergonomic handle for convenient carrying on the go

Who is this for: This VIVOHOME kit is aimed at homeowners who perform their own A/C maintenance, automotive enthusiasts working on car air conditioning, and HVAC technicians needing a compact, reliable evacuation and charging solution for light commercial and residential systems. It’s especially useful when portability, clear gauge readings and straightforward hose/adaptor compatibility are priorities.
