VIVOHOME HVAC Manifold Gauge Set for R134a/R1234yf — Quick Couplers & Can Taps

VIVOHOME HVAC Gauges are a full professional-grade automotive A/C manifold kit that measures pressure, connects quickly to R134a and R1234yf systems, and includes can taps and adapters for on-vehicle service.

This complete manifold gauge set gives technicians and DIYers the tools to diagnose, evacuate, and recharge modern vehicle air-conditioning systems. Designed to work with both older R134a and newer A2L refrigerants like R1234yf, the kit combines robust construction with user-focused features—durable gauges, reinforced hoses, quick couplers, and universal can taps—so you can perform service tasks accurately and safely.

How does this kit help me diagnose an A/C problem?

The dual-gauge manifold provides accurate high- and low-side pressure readings so you can identify leaks, blockages, or compressor issues. The dry-dial gauge cores and a calibration screw help maintain reliable measurements, while the unloading valve lets you relieve excess pressure safely.

• High- and low-side pressure monitoring for system assessment
• Calibration screw keeps accuracy within narrow tolerances
• Unloading valve for controlled pressure release
• Dry-dial design resists freezing and impact for tough conditions

What fittings and hose features come with the set?

The kit includes three five-foot PVC hoses that are color-coded for instant identification and reinforced for high working pressure and burst resistance. Brass fittings and an aluminum manifold body resist corrosion and provide secure, leak-free connections during charging and recovery operations.

• Red, blue, and yellow hoses, each 5 ft long with four reinforcement layers
• Working pressure rated to 600 psi and burst-rated to 3000 psi
• Premium brass fittings and aluminum manifold body for durability
• Lock valves on hoses to maintain secure service connections

Can I use this set on both R134a and R1234yf vehicles?

Yes—the manifold and included accessories are compatible with R134a, R1234yf, and other common refrigerants such as R404a. The package contains self-sealing can taps for both refrigerant types plus male/female adapters to fit varied service ports, enabling safe connection across multiple vehicle platforms.

• Self-sealing can taps for R134a and R1234yf cylinders
• Two 1/4" male to 1/2" female adapters (LH and RH threads) included
• Quick couplers for fast, secure hookups on service ports
• Supports vacuum operations, recharging, and basic recovery tasks

How portable and serviceable is the kit during field work?

The set is built for mobile use: a hanging hook enables hands-free gauge viewing while working under the hood, and the included carrying case keeps components organized for transport. Robust materials and replaceable fittings make the kit a long-term shop asset.

• Sturdy hanging hook for convenient, hands-free operation
• Compact carrying case for tidy storage and on-the-road mobility
• Replaceable parts and corrosion-resistant materials extend service life
• Engineered to withstand typical automotive workshop conditions

Who is this for: The VIVOHOME HVAC manifold gauge set suits professional mechanics, mobile technicians, and serious DIY enthusiasts who service automotive A/C systems. It’s ideal for shops updating to R1234yf-capable gear, owners who need a robust and accurate diagnostic kit, and anyone wanting a portable, all-in-one solution for refrigerant charging and basic troubleshooting.
