The Lichamp A301 manifold gauge set is a 3-way professional automotive A/C diagnostic kit designed for charging, evacuating and checking R134a, R22, R12 and R502 systems.

Built for technicians and DIYers, this compact kit combines large, easy-to-read gauges, heavy-duty brass fittings and three 5-foot high-impact hoses so you can service vehicle A/C systems with confidence. The set includes couplers, self-sealing puncture taps, adapters and a sight glass so you can monitor refrigerant flow while you work. It’s intended for diagnostic and service tasks such as pressure checks, freon charging and basic recovery or evacuation support when used with compatible recovery equipment.

How accurate and readable are the gauges?

The Lichamp gauges feature oversized colored dials with Fahrenheit units and clear markings for quick pressure reading on the job. The red high-side dial is rated to 500 psi and the blue low-side dial to 350 psi, giving you the range needed for most automotive systems. A sight glass helps you confirm liquid refrigerant flow during charging.

• Extra-large, color-coded dials for fast visual checks
• Red high-side 500 psi and blue low-side 350 psi ranges
• Sight glass to observe refrigerant flow while charging

What hoses and fittings come with the set?

This kit includes three reinforced 5-foot hoses rated for 600 psi working pressure and up to 3000 psi burst pressure, built with thickened bodies and precise valve core depressors. Fittings are brass and aluminum for corrosion resistance and durability under frequent use. The package also supplies adjustable R134a adapters, ACME adapter, valve core tool and gloves so you can connect to a range of service ports.

• Three 5 ft heavy-duty hoses with 45° bend on one end for tight access
• Brass and aluminum couplers, ACME adapter and valve core remover
• Includes two puncture self-sealing can taps for refrigerant cans

Can I use this for charging, evacuation or recovery work?

The Lichamp A301 is built to perform charging, pressure diagnostics and preliminary evacuation tasks; it’s compatible with R134a, R22, R12 and R502 refrigerants. For full recovery or certified refrigerant handling, pair this manifold with an appropriate certified recovery machine and follow local regulations. The gauges and sight glass make it easy to monitor system behavior during service procedures.

• Compatible with common automotive refrigerants: R134a, R22, R12, R502
• Good for freon charging, pressure checks and evacuation assistance
• Use alongside certified recovery equipment for full reclamation work

How durable and serviceable is the kit?

Constructed with upgraded gauge shells and all-metal fittings, the set resists wear from shop use and accidental drops. The precise valve depressors and sturdy hose construction reduce leaks and improve connection reliability over time. Replacement parts are standard sizes, making maintenance straightforward for garage environments.

• Upgraded metal gauge housings to withstand heavy use
• Durable brass and aluminum components for corrosion resistance
• Standard-sized adapters and hoses for easy replacement

Who this is for: The Lichamp A301 is aimed at automotive technicians, experienced DIY mechanics and small shop owners who need a reliable, full-featured manifold gauge set for routine A/C service. It’s suitable for diagnosing system pressures, charging refrigerant and supporting evacuation when used with proper recovery equipment. If you require certified refrigerant reclaim operations, use this kit alongside approved recovery units and adhere to safety and environmental regulations.
