VECOTOOLS HVAC Manifold Gauge Set — 3-Way Brass Manifold, 3 Hoses, Plastic Carry Case

VECOTOOLS 3-way brass manifold gauge set is a complete HVAC charging and diagnostic kit with brass manifold, three color-coded hoses, service accessories, and a durable plastic case for organized transport.

Whether you troubleshoot automotive air conditioning or service household HVAC equipment, this VECOTOOLS manifold gauge set brings the essential tools together in one compact kit. The solid brass 3-way manifold with blue control valves and two black-dial gauges pairs with three color-coded, high-pressure hoses and a set of service fittings to handle common refrigerants like R134a, R12, R22, and R502. Everything nests in a molded plastic carrying case so you can move between job sites with minimal fumbling.

How does this manifold gauge set help me diagnose an AC system?

The dual gauges display both high- and low-side pressures so you can read system pressures directly and compare them to expected values for the refrigerant in use. Accurate pressure readings let you identify leaks, compressions issues, and charge imbalances without guessing.

• Two clear black-dial gauges with Fahrenheit scale for high and low side monitoring.
• Three 4-foot hoses (red, blue, yellow) rated 600 PSI working, 3000 PSI burst for safe readings.
• Brass manifold with blue control valves for reliable flow control and corrosion resistance.

What charging and service accessories are included for refrigerant cans?

This kit includes practical fittings to connect to common service ports and refrigerant cans—so you can charge systems and perform maintenance without sourcing extra parts. Quick couplers and can taps make the charging process quicker and cleaner.

• Pair of quick couplers labeled H (high) and L (low) for R134a service ports.
• Puncturing can tap and a self-sealing can tap for controlled refrigerant transfer.
• Valve core tool and small accessory pouch for routine valve and fitting work.

Is the build quality durable enough for fieldwork?

Key components are made from solid brass and the gauges have a protective blue rubber coating, providing corrosion resistance and extra impact protection for daily use. The molded plastic carrying case organizes the kit and protects instruments during transport and storage.

• Solid brass 3-way manifold and blue control valves resist corrosion and wear.
• Protective rubber-coated gauges reduce risk of damage from drops and knocks.
• Durable plastic case with compartments keeps hoses and accessories secured.

Which refrigerants and applications is this set compatible with?

The VECOTOOLS manifold gauge set supports the common service refrigerants used in automotive and residential systems, allowing broad applicability across diagnostics, repair, and charging tasks. It’s built for both professional and DIY settings where these refrigerants are in use.

• Compatible with R134a, R12, R22, and R502 refrigerants.
• Suited for automotive AC, home air conditioning units, and small refrigeration checks.
• Color-coded hoses simplify connections for high, low, and service/charging lines.

Who is this for? Technicians, mechanics, and informed DIYers who need a dependable, all-in-one manifold gauge kit for routine HVAC troubleshooting and refrigerant charging will find this VECOTOOLS set useful. It combines durable brass construction, clear gauges, practical service fittings, and a transport case to reduce the number of separate tools you must carry, making it a solid choice for field service, garage work, and at-home AC maintenance projects.
