AC manifold gauge set for R134a with hoses and case

AC manifold gauge set for R134a – check, evacuate, charge

• ✔ Two gauges: low pressure (blue) and high pressure (red), clearly readable scales
• ✔ Manifold block with sight glass and two shut-off valves
• ✔ Three hoses of 1.5 m in blue, yellow and red – 600 PSI working pressure, 3,000 PSI burst pressure
• ✔ Quick couplers for high and low pressure service ports on R134a systems
• ✔ Brass fittings, sturdy build for everyday workshop use
• ✔ Everything in a carry case with insert – nothing lies around loose

The manifold gauge set is the basic tool for any work on a vehicle air conditioning system. You use it to measure high and low pressure while the system runs, to spot undercharge, overcharge and compressor problems, and to connect the system to a vacuum pump or refrigerant cylinder.

What you need the set for

• Pressure check: read high and low pressure while running and compare with the target values
• Pulling a vacuum: yellow hose to the vacuum pump, dry the system and check it for leaks
• Charging: yellow hose to the refrigerant cylinder, meter the quantity through the valves
• Fault finding: the sight glass shows bubbles – a clear sign of too little refrigerant

Layout

The manifold block carries both gauges and two hand valves. On the left is the low pressure port (blue), on the right the high pressure port (red), in the middle the service port (yellow) for pump or cylinder. The hanging hook lets you hang the set in the engine bay and keep both hands free.

Please note: the set is designed for systems with R134a. R1234yf needs different couplers and a separate service unit, because the refrigerants must not be mixed.

Important note on certification

Work on air conditioning systems with fluorinated refrigerants requires a certificate of competence (EU Regulation 517/2014). Refrigerant must not be released into the atmosphere. This tool is intended for specialist businesses and certified users.
