Lichamp AC Manifold Gauge Set for R1234YF R134a R404a — 4-Valve Kit with 4x 5ft Hoses & Sight Glass

The Lichamp AC manifold gauge set is a four-valve diagnostic and service kit built to read, evacuate, charge and help troubleshoot automotive A/C systems using R1234YF, R134a or R404a refrigerants.

Designed for technicians and DIY mechanics, this compact kit combines extra-large, color-coded gauges with four 5-foot high-impact hoses and a full complement of adapters and tools. The gauges show both pressure and temperature (Fahrenheit), while the included sight glass lets you monitor liquid refrigerant flow during charging. Durable brass and aluminum components, plus reinforced hose construction, make the set suitable for frequent garage or shop use.

How accurate and readable are the gauges for fast diagnostics?

The Lichamp set uses oversized, color-coded dials to provide clear, quick readings under workshop lighting. Each dial includes Fahrenheit markings and is protected by an upgraded metal shell to resist drops and wear.

• Red high-pressure gauge rated to 800 psi; blue low-pressure gauge rated to 550 psi
• Large numerals and contrasting colors for rapid interpretation
• Rugged housing reduces measurement drift from impacts
• Sight glass for visual verification of refrigerant flow during charging

What connections and adapters are included to work with different refrigerants?

This kit ships with multiple adapters so you can service vehicles using R1234YF, R134a or R404a without improvising fittings. Adapters attach quickly and the hose ends feature a 45° bend for easier access to tight service ports.

• Two adjustable R134a adapters and two R134a-to-R1234YF conversion adapters
• Adjustable can tap and tank adapter for refrigerant cylinders
• 45° hose ends and precise valve-core depressors for secure connections
• Valve core remover and calibration screwdriver for on-the-spot maintenance

Are the hoses and valves durable enough for workshop use?

The set includes four heavy-duty, five-foot hoses built to withstand repeated service cycles. Reinforced bodies and solid valve components extend service life and reduce the chance of leaks during charging or evacuation.

• Four 5 ft hoses rated to 800 psi working pressure and 4000 psi burst pressure
• Thickened hose construction with integrated valve-core depressors
• All-metal brass and aluminum valve and fitting construction
• Compact manifold body designed to resist damage from accidental drops

What tools come with the kit to support field calibration and repairs?

Beyond gauges and hoses, the Lichamp kit provides small, practical tools so you can adjust fittings, swap adapters and replace valve cores without leaving the vehicle. These extras save time and keep service tasks on schedule.

• Calibration screwdriver for fine-tuning gauge zero and accuracy
• Valve core remover for quick core replacement or clearing
• Protective gloves included to help maintain a clean, safe working area
• Compact carrying layout keeps accessories organized and accessible

Who this is for: The Lichamp 4-valve manifold gauge set is aimed at automotive technicians, independent mechanics and informed DIYers who need a versatile, workshop-grade tool for diagnosing and servicing A/C systems using modern refrigerants (R1234YF, R134a, R404a). It fits small repair shops and home garages where dependable gauges, long hoses and multi-adapter flexibility reduce service time and improve consistency during charging, evacuation and troubleshooting tasks.
