VIVOHOME HVAC Manifold Gauge Set R134a - 5ft Hoses, Oil‑Filled Gauges, Brass Quick Couplers

The VIVOHOME R134a 5ft HVAC manifold gauge set is a complete, shock‑resistant toolkit for charging, testing, and maintaining R134a and other common refrigerant automotive and HVAC systems.

This compact professional manifold kit combines three color‑coded 5ft hoses, oil‑filled high and low pressure gauges, brass quick couplers, and two can taps to help technicians and DIYers diagnose, evacuate, and top up air conditioning systems. Designed for everyday shop use, the set prioritizes accurate readings, leak‑reduction at connections, and durable hose construction. Note: the kit is not compatible with R410a systems.

How accurate and durable are the pressure gauges?

The pair of large, oil‑filled pressure dials provide stable needle movement and clearer visibility under vibration and shop conditions. They are built to resist shock and to preserve calibration for repeated use.

• Oil‑filled design reduces needle flutter for steady readings.
• Large clear faces with color‑coded scales for quick interpretation.
• Shock‑resistant housing extends service life in busy workshops.

Can this set handle different refrigerants and vehicle systems?

Yes — the manifold is compatible with R134a, R12, R22, and R502 refrigerants, making it versatile for many automotive and light HVAC applications. The standard 1/4" SAE ports and included adapter simplify connections across fittings you'll commonly encounter.

• Works with multiple refrigerants for cross‑system servicing (not R410a).
• Standard 1/4" SAE ports for broad compatibility with tools and hoses.
• Includes 1/4" to 1/2" adapter to fit varied service valves.

How does the kit prevent refrigerant leaks while charging and testing?

Precision‑machined brass connectors and high‑quality rubber gaskets create tight seals at every connection point. The set is engineered to minimize refrigerant loss during charging and pressure tests, helping maintain system integrity and conserve refrigerant.

• Brass fittings resist corrosion and maintain precise threading tolerances.
• Rubber gaskets provide reliable, reusable seals under pressure.
• Included quick couplers speed safe connection and disconnection.

What features help with ease of use for beginners and pros?

The VIVOHOME manifold set balances professional features with user‑friendly layout: color‑coded hoses, easy valve control, and two can taps for direct refrigerant access. The 5ft hose length gives mobility around the vehicle while staying manageable in a workshop setting.

• Three color‑coded 5ft hoses mark high, low, and service/charge lines.
• Ergonomic valve knobs and clear gauge faces speed diagnostics.
• Two can taps allow convenient topping from refrigerant cans.

Who this is for: The VIVOHOME R134a manifold gauge set suits automotive technicians, HVAC maintenance professionals, and informed DIYers who work on car air conditioning or light HVAC systems requiring R134a, R12, R22, or R502 refrigerants. It is especially useful for users who need a durable, portable kit with clear gauges, leak‑reducing fittings, and flexible hose lengths. If you require servicing for R410a systems, choose an appropriate R410a‑rated manifold instead.
