VIVOHOME HVAC Manifold Gauge Set for R134a/R410a R32 R22 — 4‑Way Aluminum Kit with Dry‑Dial Gauges & Reinforced Hoses

The VIVOHOME HVAC Manifold Gauge Set is a complete, heavy-duty automotive A/C diagnostic and charging kit compatible with R134a, R32, R410a and R22 systems.

This compact toolkit bundles a four-way aluminum manifold, four reinforced color-coded hoses, precise dry-dial gauges and a selection of adapters to let technicians and DIYers test pressures, evacuate systems and recharge refrigerant with confidence. Built for frequent shop use, the set prioritizes durable materials, clear readings and safe handling features like high burst-pressure hoses and lock valves.

How accurate are the pressure readings and how are they protected?

The twin dry-dial gauges are designed for reliable, repeatable pressure readings essential to diagnosing A/C performance. The wear-resistant gauge cores and impact-resistant faces reduce drift from physical wear, while a calibration screw lets users fine-tune accuracy to maintain performance.

• Dry-dial gauge design resists moisture and freezing for cold-weather use
• Calibration screw for maintaining precision within ±1.6%
• Unloading valve to safely relieve excess pressure before service

What safety and durability features does the set include?

The set combines an anodized aluminum manifold body with brass fittings to resist rust and handle repeated connections. Hoses are multi-layer reinforced PVC rated for high working pressures and extremely high burst pressure to reduce rupture risk during heavy-duty procedures.

• Four-layer reinforced PVC hoses with 800 psi working pressure
• 4000 psi burst pressure rating for added safety margin
• Locking valves and sturdy brass connectors to prevent accidental leaks

Which refrigerants and tasks is this manifold set compatible with?

This VIVOHOME kit supports a wide range of modern automotive refrigerants and common A/C shop tasks, making it useful across vehicle platforms and service needs. It is suitable for vacuuming, pressure checks, controlled refrigerant charging and can assist with coolant recovery workflows when paired with the proper equipment.

• Compatible with R134a, R32, R410a, R404a and related refrigerants
• Supports vacuum diagnostics, charging and evacuation procedures
• Includes self-sealing and puncture can taps plus multiple adapters for vehicle connections

What comes in the kit and how does it improve workflow?

The package includes everything needed for many on-vehicle A/C jobs so technicians spend less time gathering parts. Color-coded hoses and a hanging hook simplify setup and hands-free operation, while the carrying case keeps components organized for mobile work.

• Four-way manifold with two gauges and unloading valve
• Four color-coded 5-foot hoses with lock valves and quick couplers
• Adapters: two 1/4" male to 5/16" female, one 1/4" male to 1/2" female, plus can taps

Who is this for: The VIVOHOME HVAC Manifold Gauge Set suits professional mechanics, HVAC technicians and experienced DIYers who service automotive air conditioning systems and require a portable, durable manifold kit. It’s particularly useful for shops that handle multiple refrigerant types and need accurate pressure diagnostics, heavy-duty hose performance and a complete accessory set to streamline routine A/C maintenance and charging tasks.
