VEVOR AC Vacuum Pump and Gauge Set, 4.5 CFM 127 L/min, Single Stage Rotary Vane HVAC Vacuum Pump, Manifold Gauge Kit, for R134a R22 R410a R1234YF R32, with Carry Bag, for Auto HVAC Air Conditioning

Automotive AC Vacuum Pump Kit with 4.5 CFM Single-Stage Pump

This automotive AC vacuum pump kit is a single-stage rotary vane pump with a 4.5 CFM/127 L/min capacity and is driven by a 1/3 HP, 250W motor. Instead of a stand-alone pump, it is a complete kit designed for users who need everything for a complete A/C service in one box, rather than sourcing gauges, hoses, and adapters separately.

Its single-stage design makes the pump itself more compact and lighter duty than two-stage units, better suited for occasional automotive A/C work, DIY car maintenance, or smaller refrigeration tasks rather than continuous shop use. If you're building your first A/C service kit, the fact that the pump is matched to a manifold gauge set and hose assembly from the start takes the guesswork out of finding compatible components. This kit format is as much about convenience and completeness as it is about raw pump performance.

Manifold Gauge Set Offers ±1.6% Pressure Reading Accuracy

The included manifold gauge set offers ±1.6% measurement accuracy, providing readings precise enough to correctly diagnose A/C system pressure during charging or troubleshooting. This level of accuracy is critical in automotive work, as even a small amount of overcharging or undercharging a system can affect cooling performance or damage components over time.

The gauges feature a dual-unit display so you can read in different measurement formats without needing a separate conversion chart, and a clear sight glass provides another point of at-a-glance monitoring while you work. The gauge housing's high-pressure resistance also means it can withstand repeated connections and disconnections during service jobs. If you need accurate readings to properly charge a system, this gauge set takes the guesswork out of the equation.

Three-Color Hose Rated for 800 to 4000 PSI Working Pressure

A 3.94 ft / 1.2 m three-color hose set in red, blue, and yellow is included for quick identification of high-side, low-side, and utility connections during service. The color coding minimizes the chances for a mid-job line cross-connection, something to consider when you're working under the gun or in low-light shop conditions.

These hoses have a working pressure range of 800 to 4000 PSI. This gives you enough margin to work on higher-pressure refrigerant systems without worrying about hose failure during evacuation or charging. The hose assembly has robust fittings on all connection points and is designed to stay sealed during the vacuum and recharge process. For those building their own A/C service setup, hoses rated this high eliminate one of the more common failure points in lower-quality kits.

Adapters and Couplers Included for R134a, R410a, and R1234yf Systems

The kit comes with an R134a-to-R1234yf adapter, an R134a quick coupler, an R410A 1/4” SAE-to-5/16” SAE adapter, and R134A and R1234yf can taps to accommodate the connection types used in most popular automotive refrigerant systems. The kit is compatible with R134a, R22, R410a, R1234YF, and R32 refrigerants, so it will work on both older and newer vehicles with updated refrigerant types.

These adapters are included from the start, so you won’t have to hunt down individual fittings when working on a vehicle that uses a different refrigerant standard than the last job. If you’re a technician or a DIYer who works on multiple types of vehicles, this range of adapters can turn what could be several separate purchases into a single complete kit. That coverage is one of the reasons this model is an automotive AC vacuum pump kit and not just a pump with optional add-ons.

5 Pa Ultimate Vacuum from a 4-Pole High-Torque Motor

The pump reaches an ultimate vacuum of 5 Pa (37.5 microns) and is driven by a 4-pole high-torque motor to ensure consistent performance throughout the entire evacuation cycle. While this single-stage unit doesn't pull as deep a vacuum as a two-stage pump, 5 Pa is still sufficient for pulling moisture and air from smaller automotive A/C systems during routine service.

The built-in oil capacity is 0.26 qt (250 ml), allowing the unit to run steadily for extended periods. The condition of the oil directly determines how consistently the pump maintains its rated vacuum depth over repeated use. It’s that checking and maintaining the oil level helps preserve performance across multiple service jobs, rather than letting vacuum depth degrade over time. For lighter, periodic A/C work, this motor-and-vacuum combination provides reliable results without the bulk of a heavier two-stage system.

Automotive AC Vacuum Pump Kit Packs into a Portable Carry Bag

The complete automotive AC vacuum pump kit, which includes the pump, gauge set, hoses, adapters, couplers, and oil bottle, fits inside the included portable carrying bag for organized storage and easy transport between work sites. Portability is important for mobile technicians or anyone who services vehicles in different locations, rather than at a single, fixed shop bench.

Another benefit of having everything in one bag is that you’re less likely to lose smaller items between uses, such as can taps or adapters, which is an issue when kit pieces are stored separately. For the DIYer who only pulls this kit out once in a while, having everything pre-organized in one case means less setup time before you get to work on the service. The carry bag converts a multi-piece kit into a single grab-and-go unit for the next job.
