VIVOHOME 4-Way HVAC Manifold Gauge Kit – R134a/R1234yf Compatible with Quick Couplers & Dual Dry-Dial Gauges

The VIVOHOME 4-way HVAC manifold gauge kit is a complete, heavy-duty diagnostic and service tool for automotive and light commercial A/C systems compatible with R134a and R1234yf.

This kit combines a four-valve aluminum manifold with high-accuracy dry-dial gauges, four reinforced color-coded hoses, quick couplers, and dual self-sealing can taps so you can measure pressures, evacuate systems, and charge refrigerant confidently. Built for repeated field use, the set balances portability and rugged construction with compatibility across common refrigerants including R134a, R1234yf, R410a, R32, and more.

How does this manifold kit simplify automotive A/C troubleshooting?

The 4-way manifold lets you monitor both high and low side pressures simultaneously while isolating or venting lines for controlled testing. The two calibrated dials and unloading valve let you take repeatable readings and safely relieve excess pressure before service.

• Dual dry-dial gauges with ±1.6% calibration screw
• Unloading valve for controlled pressure release
• Four-color hoses for instant high/low/charge/evacuation identification
• Quick couplers for fast connect/disconnect on service ports

What safety and durability features protect the tool during heavy use?

Key components are selected for corrosion resistance and impact performance. The manifold body is machined aluminum, fittings are brass for leak-resistance, and hoses use four reinforcement layers rated for high working and burst pressures.

• Aluminum manifold body and premium brass fittings resist rust
• Hoses rated to 800 psi working and 4000 psi burst pressure
• Impact-resistant gauge cores and wear-resistant dry dials
• Lock valves on hoses prevent accidental discharge during service

Which adapters and accessories are included for wide compatibility?

The kit includes multiple adapters and two self-sealing can taps so you can connect to R1234yf and R134a service ports and standard refrigerant canisters without extra purchases. Threaded adapters cover common male/female sizes and LH/RH applications for broad system support.

• Two self-sealing can taps for R1234yf and R134a cans
• Two 1/4" male-to-5/16" female adapters and two 1/4" male-to-1/2" female (LH/RH)
• Four quick couplers and lock-valve equipped hoses
• Carrying case and hanging hook for organized, hands-free work

Who is this for? This VIVOHOME manifold gauge kit is aimed at professional technicians, independent repair shops, and serious DIYers who service automotive or small commercial A/C systems and need a portable, reliable set that handles modern refrigerants. It suits users who require accurate pressure readings, durable hardware for repeated field service, and immediate compatibility with R134a and R1234yf setups without buying extra adapters. If you want a robust, all-in-one diagnostic and charging kit that organizes tools for on-the-job efficiency, this set fits the need.
