What to know before buying
Listing details to confirm
The listing’s gauge description says the dial units are Celsius while giving pressure ranges in PSI. It describes three 5-foot hoses but does not specify included adapters or refrigerant-specific couplers, and the stated gauge functions do not establish which accessories are supplied. Confirm the requirements of the refrigerant and vehicle before use.

Who is it for?
A good fit for
- Automotive DIYers or technicians seeking an analogue manifold gauge set for the listed refrigerants.
- Users who need to observe system pressure and perform the listed charging, leak-detection or evacuation tasks.
Less suited to
- Buyers who need a digital readout or a clearly itemized set of adapters and refrigerant-specific couplers.
- Anyone needing a gauge set whose scale units and included connection hardware are fully specified in the listing.

The available evidence is limited to aggregate star ratings, with a generally positive distribution alongside a smaller one-star share. That offers only a cautious indication of customer sentiment and does not identify what buyers liked or disliked. For this gauge set, confirm the scale markings and kit contents against your intended service work rather than treating the aggregate as evidence of performance.
Frequently asked questions
Which refrigerants does the listing name?
It lists R134A, R1234YF, R404A and R12. Confirm that the set’s connections and your service procedure match the specific vehicle or system.
What pressure ranges are specified?
The blue dial is listed as -30 - 260 PSI and the red dial as -30 - 550 PSI. The listing also says the gauges use Celsius units, so verify the scale markings before relying on a reading.
Are hoses included?
The feature text claims three 5-foot hoses. The explicit included-components field names only an AC Gauges Set, so verify the selected listing’s kit contents before purchase.
Does this kit include a vacuum pump?
Vacuum-pump evacuation is listed as a function, but no vacuum pump appears in the supplied included-components entry. The function statement alone does not establish that a pump is bundled.
