VIVOHOME AC Vacuum Pump and 4‑Way Gauge Set — Upgraded 1/3 HP 5 CFM, 37.5‑Micron Ultimate Vacuum

The VIVOHOME Upgraded 1/3 HP 5 CFM 1‑Stage AC Vacuum Pump and 4‑Way Gauge Set is a complete HVAC service kit designed to evacuate, test, and recharge refrigerant lines safely and efficiently.

This all-in-one set brings a high-capacity vacuum pump together with a precise 4-way manifold gauge and essential accessories so technicians and knowledgeable DIYers can handle vehicle air conditioning, refrigeration, mini-splits, and other refrigeration systems. The kit balances portability with professional-grade components: a one‑piece shell vacuum pump with a copper motor, a four‑color hose network with reinforced sealing, adapters for common refrigerants, plus oil and leak‑detection tools to keep jobs moving.

How does this vacuum pump perform for deep evacuation?

The pump’s 1/3 HP motor spins at 2880 RPM and is built to reach an ultimate vacuum down to 37.5 microns, giving you the deep draw needed before charging refrigerant. A one‑piece housing reduces leak paths, and an inner backflow valve protects the pump from liquid return during service.

• 5 CFM displacement suitable for rapid evacuation of small to medium systems
• Pure copper motor for steady torque and heat tolerance
• Oil sight glass (250–360 ml) for quick oil-level checks
• Mesh vent and durable shell improve cooling and longevity

What makes the 4-way manifold gauge set accurate and durable?

The included 4-way manifold is designed for reliable system monitoring and switching between charge, recovery, and vacuum modes. Color-coded ports and a hose locking valve make connections clearer and reduce the chance of leaks while four‑layer hoses resist pressure and wear.

• Four color-coded hoses with leak-proof seals and multi-layer reinforcement
• Hose locking valve adds secondary protection during service
• Clear, calibrated gauges for monitoring pressure and vacuum steps
• Compatible fittings for a range of refrigerants and line sizes

Which refrigerants and fittings are supported for real-world jobs?

The kit ships with SAE adapters for 1/4" and 1/2" hose sizes plus two R410a adapters (1/4" to 5/16"), allowing compatibility with many common systems. It supports R12, R134a, R22, R502 and R410a, covering automotive A/C, home refrigeration, and commercial mini-split servicing without needing immediate extra adapters.

• Adapters included for 1/4" and 1/2" SAE hoses and R410a conversions
• Works with R12, R134a, R22, R502, and R410a refrigerants
• Two can taps and two R134a couplers for convenient recharging
• Leak detector and oil supplied for thorough maintenance workflow

Who is this for? The VIVOHOME kit is aimed at professional HVAC technicians, automotive A/C specialists, and experienced DIYers who need a portable yet powerful evacuation and charging solution. It’s especially useful for shops that handle multiple refrigerant types and for mobile techs who require a compact case, clear gauges, robust hoses, and a pump capable of reaching deep vacuum levels before charging. If you need a ready-to-use service pack that reduces trips for extra fittings or oil, this kit covers the essentials for routine maintenance, evacuation, leak testing, and recharge operations.
