We strive to be the industry leader for providing excellent products. While many AUTO refrigerant changing kits are designed for AUTO AC, even though some of them claim to support Mini-split and HVAC, it could be dangerous such systems to be used for Mini-split. As R410a refrigerant requires higher pressure than an AUTO AC system, (an AUTO AC refrigerant system designed with low-pressure latency), it could be burst when used for Mini-split system. Kozyvacu Mini Split/HVAC/AUTO AC Repair Complete Tool Kit is designed to be a truly complete tool kit that fits both R134a and R410a systems. All the components have been designed and tested for high burst pressure and boast great durability and high performance. Whether applied to commercial or non-commercial uses, this tool kit can do it all!F eatures [Complete Set] A Complete refrigerant changing tool kit for R410a, R134a, R134, R134A, R12, R22, R22A, R404A, R407C or R502. Especially designed for Mini-Split and HVAC system. [Gauge] Blue gauge (low): 2-1/2" diameter, 0-500 PSI; Red gauge (high): 2-1/2" diameter, 0-800 PSI. Max working pressure: 800PSI, Burst pressure: 4000PSI. [Three Colored Hoses] Brass 'Quick Seal' fittings - 45 degrees on one end, straight on the other - providing a leak-free seal. Sets of 60 inches long, 1/4 inch yellow, blue, and red hoses; 800 PSI working pressure; 4000 PSI burst pressure, Hose ends feature a strong, six-sided crimp that provides a secure, reliable connection between the hose and barb even at maximum pressure. Red and Blue hoses feature one end ¼” connector to connect with gauge and another end at 5/16” to connect R410a system or convert to fit R134a system. The yellow hoses have both ¼” connector to connect gauge and refrigerant can or AC system. [Vacuum Pump] High-performance vacuum pump with high torque design for easy startup and efficient operation and a Die-Cast Aluminum Housing. Cast aluminum housings make the pumps lightweight, yet durable. Easy to start and maintenance free, the thermally protected motor is durable for long time duty. While an AC system requires 500microns ultimate vacuum, Kozyvacu TA450 delivers better than 150 microns to ensure the vacuum meets your requirements.

Review: Great pump for the money. - I purchased this vacuum pump for two purposes. First was to pull a vacuum on a newly installed air conditioning system. I was able to pull just a tad over 30in/Hg of vacuum which was exactly what was needed per the systems recommendations. It was able to achieve this in just a few seconds, and was able to hold the vacuum for over 30 minutes even after being shut off. The pump has since then lived its life connected to a vacuum former that I use to make firearm holsters, mag pouches and knife sheaths. The pump again achieves 30in/Hg of vacuum on a regular basis. The supplied bottle of oil has lasted for just under a year, and I expect it to last another 6 months at minimum. The pump is fairly quite, and works quickly. The fittings are standard with clean brass threads. Review: Great little vacuum pump - TA-450 works great. Fill with supplied oil and started it on drawing down our auto AC which took only a few minutes but we ran it the recommended 45 minutes for most AC systems. No unusual noise or issue and it really drew the vacuum. Comes in a nicely tight foan package so it was not damaged as some suggest. Only question is how long between oil changes and if replacement parts are available when it does need new vanes. Time will tell and we hope when it does need parts the seller can support this pump. So far we have had no issues and love this pump. ## Features - ✅High Performance - The Kozyvacu Vacuum Pump for AC repair tools delivers excellent performance with a high flow rate of 4.5 CFM, making it a perfect choice for Car AC or HVAC applications. - ✅Versatile - This vacuum pump is versatile, ideal for both workshop applications like HVAC, Auto AC, and automotive systems, and widely used in household and commercial tasks such as refrigeration maintenance, printing machinery, and vacuum packaging, e-poxy resin degassing, wine degassing, thermoforming. - ✅Easy to Use - The vacuum pump comes with an AC vacuum pump kit, making it easy to set up and use.

I wonder which it is? That is nearly a 400% difference. **Q: What is the warranty?** A: One year warranty. please refer to www.kozyvacu.com website for details **Q: What is needed to pull an R12 AC system** A: This will work on r12 or r134a. **Q: does it have anti-siphon valve in event power to pump is disrupted?** A: The seller must not know but this has NO CHECK VALVE, NO ANTI SIPHONING. Trust me, I've used this several times and I like to put mine on a timer. I found out the hard way. A bunch of oil spilled back in my vacuum chamber and lost over $500 worth of product. Kozyard LLC must not care that people use these things on equipment that will cost a lot of money if they tell us a bold face lie. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great pump for the money. *by C***O on November 20, 2019* I purchased this vacuum pump for two purposes.

We use this vacuum pump about 30 minutes every day. It has worked flawlessly the entire time. Last night the electric motor on it smoked and it no longer works. Oil level is good. ## Frequently Bought Together - Kozyvacu Single-Stage HVAC Vacuum Pump, 4.5CFM - Ideal for AC Repair Tools, Car AC Vacuum Pump, AC Vacuum Pump Kit, and Recovery Machine HVAC - Also Known as Bomba de Vacio A/C (TA450) - TSI Supercool Vacuum Pump Oil, Synthetic, 32 Oz., Clear (V32) - Refrigeration Technologies RT201B Nylog Gasket/Thread Sealant, 30 ml (1 Pack) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.gr/products/39477145-single-stage-hvac-vacuum-pump-4-5cfm-ideal-for-ac](https://www.desertcart.gr/products/39477145-single-stage-hvac-vacuum-pump-4-5cfm-ideal-for-ac) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-05-27*
