VIVOHOME 1/4 HP 3.5 CFM Vacuum Pump & AC Manifold Gauge Kit — Single-Stage, Includes Hoses & Thermometer

The VIVOHOME 1/4 HP 3.5 CFM single-stage rotary vane vacuum pump and AC manifold gauge kit is a portable, all-in-one toolset for evacuating, testing, and recharging automotive and light HVAC refrigeration systems.

This compact kit combines a die-cast aluminum vacuum pump with a complete color-coded manifold gauge set, hoses, thermometer and a bottle of vacuum oil — all designed to help you remove moisture and air from A/C and refrigeration lines before recharging. Built for home mechanics, mobile technicians and HVAC DIYers, the components are sized for easy transport, clear readings and compatibility with common refrigerants including R134a, R12, R22, R502 and R410a.

How does the pump remove moisture and air from my A/C system?

The single-stage rotary vane pump pulls a deep vacuum to evacuate trapped air and moisture from refrigerant lines. Removing these contaminants prevents performance loss and helps ensure accurate charge amounts when you refill the system.

• 3.5 CFM (cubic feet per minute) rated flow for efficient evacuation
• Die-cast aluminum housing for reduced weight and improved heat dissipation
• Oil sight glass and drain valve for easy oil level checks and maintenance

What does the manifold gauge set measure and how accurate is it?

The manifold gauge set reads high and low side pressures and provides a port for charging or recovery via the center hose. Large, color-coded gauges and sight glasses help you read pressures and visually confirm refrigerant flow during service.

• High- and low-pressure gauges with clear markings for common refrigerants
• Large viewing glasses allow observation of refrigerant movement
• Includes a thermometer for measuring system/vehicle temperature as part of diagnostics

Are the hoses and fittings compatible with my vehicle or AC equipment?

The kit includes three color-coded rubber hoses (red, blue, yellow) with leak-resistant fittings to simplify connections and prevent cross-connection mistakes. R410a adapters are supplied to convert between 1/4" and 5/16" service ports, broadening compatibility across modern and older systems.

• Red = high-pressure, Blue = low-pressure, Yellow = service/charging hose
• Durable, flexible rubber construction with leak-proof seals
• Adapters included for R410a and common refrigerant service fittings

What features make this kit easy to use and maintain?

The pump’s ergonomic handle and lightweight die-cast body make carrying and positioning simple; a built-in high-volume cooling fan supports longer runs. Maintenance is simplified with an oil sight glass and bottom drain valve, while the included vacuum oil and carrying bag get you started right away.

• Ergonomic grip handle and compact footprint for portability
• Oil sight glass and drain valve for quick checks and draining
• Comes with 0.35 qt (330 ml) vacuum oil and a storage bag for gauges

Who is this for: This VIVOHOME vacuum pump and manifold gauge kit is ideal for DIY automotive technicians, mobile A/C repairers, HVAC trainees and homeowners doing light refrigeration work. It fits tasks like evacuating vehicle A/C systems, checking pressure differentials, topping up refrigerant on compatible systems, and basic HVAC troubleshooting where a compact, portable vacuum source and clear pressure readout are needed.
