AUTO AC Repair Complete Tool Kit with 1-Stage 3.5 CFM Vacuum Pump, Manifold Gauge Set, Hoses and its Acccessories KZTA350001 TA350 1

The pump arrived on time, and as usual was well packaged. It has only been able to pull my empty vacuum chamber down to -25.5 Hg, but that may be due to my lid seal. I plan to change out the lid seal and retest the vacuum pump. The pump looks good and quieter than I expected. When running, it does produce a very fine mist from the exhaust/oil fill port. I’m told this is completely normal. I’ll post a more in-depth review once I change the lid gasket on my chamber and do a few stabilizing batches. This will be the more in-depth review of the Kozyvacu TA350 after using it numerous times. I have been using it to pull vacuum in a 4”x12” clear PVC vacuum chamber that I built for wood stabilization. During my first runs, I thought this pump may not be able to do the job as effectively as I had hoped. I’m happy to report that is not the case. I’m not sure if it was the crazy Oklahoma weather conditions, the refinements I made to my chamber, or a combination of those, but I’m now able to pull vacuum down to -30 Hg, which is what I’m told is nearly perfect vacuum for the wood stabilization process. Not only does this little vacuum pump seem to be operating better with time, the fine mist I mentioned has stopped. All in all, I’m very pleased with this purchase, and would not hesitate to buy this same pump again. For less than 60 bucks, delivered to your door in a couple of days, this vacuum pump is the “Deal of the day” for anyone like myself who would rather build their stabilization system than buy a complete setup.

This vacuum pump is well built and heavier than I expected. Exceptional quality build. I used it to vacuum my auto AC and it went to about 27 mg in less than 2 minutes. If left for a half and hour it goes down to about 29.5 mg, provided you don't have any air leaks. Its very sturdy and performs exceptionally well. Less noisy than I expected.

I'm happy with this pump after using it twice. I filled the oil half way between the marks, and ran it for over an hour under slight load to break it in, first. (This might not be necessary at all.) It holds vacuum just fine. **It comes with oil in a sealed bottle. After filling up the oil reservoir, you'll have extra leftover. The pump is still working after doing several A/C jobs. **I believe that the pump and other AC vacuum pumps use mineral oil for lubrication. Take opinions on here with a grain of salt!

I read the negative and average reviews. I was really concerned about buying a potential $60 paperweight. I used this way too many times in the past two weeks and am very satisfied with the results. Drop test - passed. Multiple uses - pass. Recommend - yes. I had an accumulator’s schrader valve stick which caused a leak. I have tools to replace the valve while leaving the system pressurized, but this required the accumlaotor to accept the valve and the replacement schrader valve to also be good. Fail and fail. Anyways enter the replacement accumulator and first attempt. The pump worked great and pulled a perfect vacuum. The motor was hotter than expected, but no issues. Charged the system and everything was roses and smiles. Two hours later and after a loud sound of rushing air, I discovered a spring fitting on the new accumulator failed and I lost my charge. Reset the connection and it passed the pull apart test. It appeared solid. Vacuum number 2 - worked great. I turned after pulling the vacuum and promptly sent the pump off the radiator falling to the ground. I got lucky with no damage to the pump or gauges. The gauge line sort of softened the fall. I began to recharge the system. One can in and I had to deal with another issue. Pop goes the same spring connection. Lesson one: don’t buy crap aftermarket AC stuff. Poor quality control. Bought a Motocraft and installed it. (Fit perfect) Vacuum number 3 and everything is still working great. The pump ran for over three hours in 95+ degree weather over the three vacuums. No noticeable oil loss. Solid vacuum. Met my needs and then some. I suspect there will be lemons in any process, but this one worked very well for my needs.

Removed acme and 1/4 male flare fitting to install 3/8 male flare fitting to use my vacuum tree and micron gauge.
