VIVOHOME HVAC Manifold Gauge Set for R134a/R410a/R22/R32 – 4-Valve Car A/C Gauges + 5ft Hoses

Durable 4-Valve Manifold Gauge Set for Automotive A/C Service

The VIVOHOME HVAC Manifold Gauge Set is a comprehensive diagnostic tool designed to diagnose and service vehicle air conditioning systems. It works with both A1 and A2L refrigerants, giving you a versatile option for a wide range of vehicles. Built for durability and precise readings, this kit helps you approach repairs with confidence rather than guesswork.

Designed for everyday shop use, the unit features a robust aluminum body with brass fittings that resist rust and corrosion, and a full set of components crafted for repeated use. The gauges deliver accurate readings as you monitor pressure during charging, evacuation, or vacuum diagnostics. A calibration screw helps maintain precision within ±1.6%, ensuring that readings stay reliable even after many cycles of use. An unloading valve provides a controlled way to release excess pressure, supporting safer maintenance procedures in real-world scenarios.

Hose Assembly, Color Coding, and Safety

The set includes four 5-foot hoses built with four reinforcement layers, color-coded red, blue, yellow, and black to quickly distinguish high-pressure, low-pressure, charging, and evacuation lines. Each hose is rated for up to 800 psi working pressure and 4000 psi burst pressure. With a sturdy aluminum body and premium brass fittings, these hoses are designed for long-term service in demanding automotive environments.

In addition to the four hoses, the toolkit includes a four-way manifold gauge, two quick couplers, self-sealing puncture can taps, and a selection of adapters. This combination supports R134a seasonals as well as other common refrigerants, enabling flexible service workflows without swapping parts mid-job.

Portability, Organization, and Real-World Use

Portability is a practical advantage: the set ships with a hanging hook for hands-free operation and a carrying case for organized storage and easy transport between bays or customer sites. The kit is suitable for vacuum diagnostics, recharging, and coolant recovery on automotive A/C systems, making it a versatile addition to your shop’s toolkit.

Real-world use cases include diagnosing leaks, monitoring pressures during charging, evacuating an established system, and performing periodic maintenance checks. While results depend on the vehicle and refrigerant, the gear’s design supports precise monitoring and careful handling, helping technicians work efficiently and accumulate confidence with every service.
