VEVOR 127 L/min(4.5 CFM) AC Vacuum Pump and Gauge Set, Single Stage Rotary Vane HVAC Air Vacuum Pump, A/C Refrigerant Manifold Gauge Kit, with Leak Detector Hoses, for R134a, R12, R22, R502a, R410A, R404, R407C

4-Stage Pure Copper Motor AC Gauges and Vacuum Pump Kit for 4.5 CFM Performance

This AC gauges and vacuum pump kit comes with a 150W single-stage pump featuring a 4-stage pure copper motor, a free air displacement of 4.5 CFM, and an ultimate vacuum of 5 Pa. The 4-stage copper motor design enhances electromagnetic efficiency, keeps operating temperatures cooler, and sustains output without performance degradation during long service sessions. The pump has a 260 ml oil capacity and a 1/4" SAE intake fitting, so it hooks up cleanly with typical HVAC tools right out of the box.

The one-stage rotary vane design maintains internal simplicity while providing the vacuum depth necessary for successful evacuation of refrigerant systems. Copper motor winding performance is better than aluminum alternatives in terms of heat resistance and power transfer, which is valuable during back-to-back service visits on large systems. This little pump weighs only 18.74 lbs and is 10.83 x 4.72 x 8.86 inches, making it easy to fit into tight mechanical spaces.

±1.6% Accuracy PRO Manifold Gauge with Large Viewing Glass for Real-Time Pressure Monitoring

This kit includes the updated PRO manifold gauge, which offers ±1.6% measurement accuracy, giving technicians reliable, real-time pressure readings they can trust and act on with confidence. The gauge casing has been improved for pressure resistance, making it more durable against inadvertent knocks and drops on busy construction sites. A broad viewing glass surrounds the gauge face for easy reading of the pressure values from an angle even in low-light service conditions.

Refrigerant charging and system troubleshooting require accurate pressure monitoring. Small changes in pressure can indicate an undercharge, an overcharge, or a restriction. And the 1.6% tolerance beats regular gauges, taking guessing out and making every charge or recovery process more precise. From testing superheat and subcooling to confirming system pressures after service, this gauge set gives you the information you need to make the right call.

Three Color-Coded 1200 mm Hoses Rated 800–4000 PSI for Secure Refrigerant Connections.

Three color-coded hoses, red, blue, and yellow, each measure 3.94 ft (1200 mm), providing ample reach to connect to most household and vehicle systems comfortably. All hoses are rated for working pressures of 800 to 4000 PSI, making them suitable for both low-pressure legacy refrigerants and the higher-pressure current blends in today’s systems. This color identification system eliminates the possibility of cross-connection errors during high-speed refrigerant service operations.

The 1200 mm length is a good compromise between reach and portability, eliminating the unpleasant stretching that shorter hoses demand, without adding bulk to the equipment. The ends of the hoses are fitted with leak-proof seals that maintain a constant connection under sustained pressure. In this way, you get dependable gauge readings and refrigerant transfer. Made from flexible rubber, the hoses bend naturally around equipment and do not kink or fracture in use.

Built-In Leak Detector and Multi-Adapter Set for Complete System Servicing

This AC gauges and vacuum pump kit includes an R410A adapter, R134A fast couplers, a 1/4" SAE-to-1/2" ACME adapter, two can taps, and a leak detector. Having these tools available will let you handle a wide variety of servicing needs without having to acquire additional items. The leak detector allows personnel to swiftly locate refrigerant leaks before recharge, avoiding waste and ensuring that a restored system holds pressure after servicing. Together, the provided adapters cover the most typical fit configurations for residential, commercial, and automotive applications.

With all attachments combined in one kit, there is no compatibility guesswork when ordering from numerous sources. Every adapter and coupler is matched to work well with the pump and gauge set, ensuring consistent, reliable connections from the first use. The completeness of this package is especially helpful to professionals building a mobile service kit or expanding into a new refrigerant service category.

7-Refrigerant Compatibility Across R134a, R22, R410a, R404, R407C, R12, and R502

This AC gauges and vacuum pump kit is compatible with R134a, R22, R12, R502, R410A, R404A, and R407C, offering a wide range of refrigerant compatibility for domestic HVAC, commercial refrigeration, and automobile A/C applications. Refrigerant ranges include legacy blends still used in aging equipment and high-efficiency refrigerants used in recent installations. This means no extra adapters are needed to switch between supported refrigerant types, making cross-system servicing much easier.

Broad refrigerant compatibility means a technician has to keep fewer items, reducing overhead and allowing the kit to handle more types of tasks. This kit will assist all clients of service organizations working on equipment spanning many generations, from older R22 systems to new R410A installations, with no modifications required. Thanks to its broad compatibility, it is a long-term investment that will remain valuable as client equipment evolves.

All-In-One AC Gauges and Vacuum Pump Kit with Carrying Bag for Portable Field Use

This AC gauges and vacuum pump kit includes a specialized travel case to keep all the components organized, safe, and ready for your next job. The bag includes the vacuum pump, manifold gauge set, three hoses, the leak detector, adapters, can taps, and the accompanying 330 ml bottle of vacuum oil, all in one container. The compact size and structural form of the bag make it easy to load into a service van or store on a shelf in the workshop.

The carrying bag also reduces the risk of components being misplaced or damaged between service calls and keeps the entire kit intact and ready for the field at all times. With organized internal storage, there’s less time spent searching through loose tools before every job, adding up to considerable time savings over the course of a hectic workday. In both cases, whether a professional HVAC expert or a DIY user, the organized kit style will make the entire service process more efficient.
