VEVOR AC Gauge Set — 3-Way Manifold Kit for R134A/R22/R12/R502 with 5 ft Hoses and ±1.6% Accuracy

VEVOR's 3-way AC Gauge Set is a complete freon charging and evacuation kit built to service R134A, R22, R12 and R502 systems with professional-level accuracy and durable fittings.

This compact manifold gauge kit collects everything you need to diagnose, charge, or evacuate automotive and small HVAC systems. Engineered with aluminum, forged brass, and reinforced multi-layer hoses, the set balances portability with a working pressure reserve up to 600 psi and burst resistance to 3000 psi. The gauges are designed for reliable readings in varied conditions and the kit includes quick-connect couplers and a can tap for straightforward refrigerant handling.

How accurate and reliable are the VEVOR gauges for routine AC service?

The gauges use a calibrated dual-phase design and dry dial scale to maintain readability even in cold environments; built-in calibration targets ±1.6% measurement accuracy. A transparent observation window on the manifold helps you monitor refrigerant flow during charging.

• ±1.6% precision calibration for pressure readings
• Dual-phase fill and dry dial scale for clear readings
• Transparent observation chamber to watch refrigerant transfer
• Full-range Fahrenheit temperature markings for reference

What components are included and how do they support full-cycle HVAC work?

The set arrives ready for common service tasks: diagnosis, evacuation, charging, and connection to service ports. Included adapters and couplers allow you to work with different valve types, and the hose bracket plus accessory pack keeps fittings organized during a job.

• 1 x 3-valve manifold gauge assembly for high/low lines and center service
• 3 x 5 ft reinforced PVC hoses with anti-slip clips and double-seal rings
• 2 quick-connect fittings, 1 SAE-to-ACME adapter, can tap, washers, and hook

Can this set handle different refrigerants and vehicle or home systems?

Yes—the VEVOR kit supports R134A, R22, R12, and R502, making it suitable for many automotive ACs, small home units, and refrigeration service tasks. Hoses and fittings are designed for broad compatibility and to reduce refrigerant loss during connections.

• Compatible with common refrigerants used in cars and small HVAC appliances
• Durable brass and aluminum construction for frequent field use
• 4-layer reinforced hoses rated for heavy-duty pressure scenarios

How safe and durable is the kit under heavy use?

Critical parts—manifold body, fittings, and valves—use forged brass and high-grade aluminum with a protective engineering plastic shell. Hoses feature a four-layer structure, anti-slip clips, and double-seal rings to minimize leaks and withstand pressure spikes.

• Forged brass connections resist corrosion and wear
• Aluminum manifold reduces weight while preserving strength
• Hoses rated to 600 psi working pressure, 3000 psi burst resistance

Who this is for: Technicians, DIY mechanics, and homeowners who perform regular AC maintenance or troubleshooting will find this VEVOR set useful. It suits anyone who needs a durable, all-in-one manifold kit for automotive freon charging, small HVAC system servicing, or refrigeration checks—especially when clear gauge readings, reliable fittings, and portability matter.
