VEVOR 217 L/min(3.5 CFM) AC Vacuum Pump and Gauge Set, Single Stage Rotary Vane HVAC Air Vacuum Pump, A/C Refrigerant Manifold Gauge Kit, with Hoses, Air Conditioning Refrigeration for R134a, R12, R22, R502a

4-Stage Copper Motor AC Gauge Set and Vacuum Pump for 3.5 CFM Single-Stage Evacuation

The AC gauge set and vacuum pump are driven by a 4-stage pure copper motor, which drives a single-stage rotary vane pump to a free air displacement of 3.5 CFM and an ultimate vacuum of 5 Pa. The four-stage copper winding design optimizes electromagnetic efficiency, maintains stable power output, and prevents heat accumulation during prolonged operating cycles. 1/4" SAE intake fitting for direct connection to normal HVAC manifold gauge sets, no further adapters needed.

It has a simple, serviceable one-stage rotary vane design and works well for household A/C repair, vehicle refrigerant work, and refrigerator vacuum jobs. Copper motor windings dissipate heat more evenly and are more stable in torque than aluminum-wound ones, especially when the same work involves multiple pump cycles. The pump weighs 15.87 lbs and is 10.83 x 4.72 x 8.86 inches. It’s small and light enough to be easily carried between job sites.

±1.6% Accuracy Manifold Gauge with Large Viewing Glass for Precise Pressure Monitoring

The integrated manifold gauge offers ±1.6% accuracy, providing professionals with real-time pressure readings they can count on for every phase of refrigerant service. The large viewing glass provides a broad, clear field of vision. From any angle you can clearly see the values. Basic gauges are difficult to read in low-light settings. This blend of precision and clarity enables professionals to make faster, more confident field choices.

Accurate pressure measurement is vital when charging refrigerant and diagnosing the system, since even small variations can indicate undercharging, overcharging, obstructions, or compressor problems. The ±1.6% accuracy is another benefit that makes this gauge set more professional than conventional units with broader tolerances and less accurate readings. Whether it’s testing system pressures after a repair, establishing superheat, or verifying subcooling targets, this gauge gives you the accuracy you need.

600–3000 PSI Color-Coded 1200 mm Hose Set for Secure R134a and R22 System Connections

The AC gauge set and vacuum pump also come with three 3.94 ft (1200 mm) color-coded hoses, red, blue, and yellow, with a working pressure of 600 to 3000 PSI. This range is in line with the refrigerants this kit is designed to work with: R134a, R22, R12, and R502, without the additional bulk of hoses used for higher-pressure refrigerants like R410A. Color-coded connections for the high side, low side, and service port are clearly identified, minimizing connection errors under pressure.

The hoses are 1200 mm long, which is a realistic reach for most home and automobile repair situations without creating excessive slack that could tangle around equipment. Each hose end is sealed to prevent refrigerant loss during connection and disconnection, ensuring accurate gauge readings throughout the service operation. The hose's rubber composition keeps it flexible in cooler ambient temperatures – vital when performing cold-weather servicing on outdoor units.

1/4" SAE Intake Fitting with 260 ml Oil Capacity for Compact HVAC Pump Performance

This AC gauge set and vacuum pump have a 1/4" SAE intake fitting and a 260 ml oil capacity, so you can execute long pump-downs without constantly topping up. The accompanying 330 ml bottle of vacuum pump oil is sufficient for the initial fill and as a maintenance reserve, so technicians can get to work right out of the box. The SAE fitting also means that if technicians want to expand the kit later, they can use third-party gauge sets, hoses, and ports.

Fresh, properly loaded oil is a critical key to reliably obtaining and maintaining deep vacuum levels over time. The 260 ml oil reservoir is matched to the 3.5 CFM pump, providing optimal lubrication without surplus volume that can complicate maintenance intervals. Having oil on hand can help you avoid a common setup stumbling block for new HVAC vacuum repair technicians.

R134a Quick Couplers and Can Tap Included for Fast, Tool-Ready Service Setup

The kit comprises a set of R134a fast couplers and a can tap that meets the most common connection requirements for car A/C service and domestic refrigerant top-up jobs. Quick couplers connect to vehicle A/C service ports without tools, enabling fast, clean connections that minimize service time during a busy day. The can tap offers a dependable connection for refrigerant cans, with less spillage and refrigerant waste than poorly fitting connectors.

With the accessories matched to the pump and gauge set, specialists can get started without needing to find the right components individually. The fast couplers seat tightly and release cleanly, reducing refrigerant loss at the connection point and helping to make the work environment safer. Automotive professionals who regularly service R134a vehicles can purchase this complete package of couplers, tap, pump, and gauges, pre-assembled to cover the entire workflow.

Complete AC Gauge Set and Vacuum Pump Bundle with Carrying Bag for Easy Field Transport

This AC gauge set and vacuum pump kit is delivered with all components in a specialized carrying bag: a manifold gauge, vacuum pump, three hoses, fast couplers, a can tap, and the supplied vacuum oil bottle. The bag safeguards gauge faces and hose ends from impacts and contamination when transported in a service van or a shared toolbox. The inside is designed to keep components segregated so nothing gets tangled or affects other sections of the kit in transit.

The carrying bag keeps everything together, so the kit is complete and ready for the next task without a pre-job inventory check. Loose components in individual containers are less practical for technicians working across numerous sites than the bag approach. This package is compact and weighs only 15.87 lb, making it easy to carry in one hand, especially when moving through narrow access points during residential tasks.
