About these itemsThese vacuum pump kits work with a wide range of refrigerants including R134a, R22, R12, R502, R410A, R404A, and R407C (select model limitations apply). Ideal for HVAC system maintenance, automotive A/C repairs, and refrigeration projects, they provide comprehensive support for service professionals and DIY users.Choose between 3.5 CFM or 4.5 CFM single-stage models powered by 4-stage pure copper motors. With an ultimate vacuum capability of 5 Pa and an oil capacity of 0.27 qt, these pumps provide reliable and efficient suction for deep system evacuation and performance diagnostics.Each kit includes a professional manifold gauge with ±1.6% accuracy and durable construction for long-term use. The wide viewing glass and color-coded design allow clear readings and simple operation while maintaining precise control over system pressure.All models come with 3 color-coded 3.94 ft hoses (red, blue, yellow), rated for 800–4000 PSI or 600–3000 PSI, depending on the version. Designed for clarity, durability, and quick connection, these hoses handle high-pressure environments with ease.Each set includes not only the vacuum pump and manifold gauges but also adapters (1/4" SAE to 1/2" ACME), R134a quick couplers, can taps, a bottle of vacuum oil, and a durable carry bag. The premium version includes an electronic leak detector for thorough service jobs.Key DifferencesCFM Rating: VP145 delivers 4.5 CFM airflow for faster evacuation, while VP125 variants provide 3.5 CFM for standard system sizes.Kit Completeness: VP145 is the most complete with a leak detector and more adapters, while other kits vary by coupler and tap quantity.Refrigerant Range: VP145 and VP125 (1st listing) support all 7 major refrigerants. The last VP125 model supports 4 types only (R134a, R22, R12, R502).Weight: VP145 is the heaviest at 18.74 lbs, built for higher output; the most basic VP125 model is lighter at 15.87 lbs for more portable use.Hose Pressure Rating: VP145 and full-featured VP125s offer hoses rated to 4000 PSI; the lightest VP125 kit supports up to 3000 PSI.Accessories: Only VP145 includes a leak detector and multiple R134a can taps.
