VIVOHOME 1/3 HP Vacuum Pump Kit with 4-Way Manifold Gauge Set — 4 CFM, Oil Sight Glass, R134a/R410a Adapters

This compact kit combines a durable single-stage vacuum pump with a precision 4-way manifold gauge set and a full set of accessories so you can perform routine HVAC maintenance or on-vehicle service without hunting for extra fittings. Built around a four-pole pure copper motor and an integrated one-piece housing, the pump focuses on stable vacuum performance and long-term reliability while the manifold and hose assembly provide accurate pressure readings and leak-resistant connections.

How does this kit help when evacuating an A/C or refrigeration system?

The single-stage pump produces a steady ultimate vacuum suitable for removing moisture and non-condensables before charging refrigerant. Its one-piece shell minimizes external leaks and the oil sight glass lets you watch lubricant status during long pulls.

• 1/3 HP motor running at 1440 RPM for consistent vacuum delivery
• Oil sight glass and inner backflow valve protect the pump and system
• Single-stage design optimized for HVAC, refrigeration, and auto A/C work
• Mesh vent for faster heat dissipation during extended use

What connections and gauges are included for charging and testing?

The 4-way manifold gauge set gives precise high/low readings and multiple service ports so you can monitor both sides of the system while adding refrigerant or testing for leaks. Color-coded hoses and locking valves improve safety and prevent accidental rotation under pressure.

• Four color-coded hoses: red (high), blue (low), yellow (refrigeration), black (vacuum)
• Manifold gauges calibrated for accurate pressure monitoring during service
• Hose locking valves and leak-proof seals rated up to 800 psi working pressure
• Includes SAE adapter and R410a fitting adapters for broad compatibility

Which accessories come in the kit for leak detection and refrigerant handling?

The kit includes practical fittings and tools to simplify both diagnosis and recharge jobs so you won’t need separate purchases. Two R134a quick couplers and two can taps cover common vehicle-style recharges, while the included vacuum oil keeps the pump maintained.

• Leak detector for finding system leaks before charging
• Two R134a quick couplers and two can taps (self-sealing and puncture style)
• 330 ml bottle of vacuum pump oil for immediate use and maintenance
• SAE adapter for 1/4" and 1/2" hoses and 1/4" to 5/16" R410a adapters

How durable and user-friendly is the pump for field or shop work?

Designed with practical features for technicians, the pump balance durability and comfortable handling. The integrated shell and pure copper motor reduce failure points, and the carry case and ergonomic handle make transport and storage easier between jobs.

• One-piece shell construction to reduce potential leak paths and improve durability
• Four-pole pure copper motor for reliable starts at low temperatures
• Ergonomic handle and included carrying case for portability
• Inner backflow valve to protect the motor from liquid return

Who this is for: The VIVOHOME vacuum pump and 4-way gauge set is aimed at DIY mechanics, HVAC technicians, and property maintenance teams who need a portable, all-in-one evacuation and charging solution. It suits vehicle air conditioning servicing, mini-split and residential HVAC jobs, and light commercial refrigeration tasks where accurate gauges, reliable vacuum, and the correct adapters are required for a safe, efficient service.
