Mityvac MV8500 Silverline Elite Automotive Brake/Clutch Bleeding, Diesel Fuel Priming and Vacuum/Pressure Testing Kit, Ergonomic Design, Zinc-Aluminum Die Cast, MV8510 Pump, 4.5oz Fluid Reservoir

I purchased this hand vacuum pump kit in order to vacuum and pressure test a chainsaw I am building. I had compared other options such as the widely sold sheet metal hand vacuum pump as well as other metal and plastic designs. I did not really want to pay a lot of money for something I only need to use for a few minutes at the moment so had some reservations about purchasing this pump kit, but after looking into the quality and reviews of comparable products I had serious doubts as to whether the generic sheet metal type would work at all and while I saw some good reviews of other Mityvac products I did not want to spend the extra money only to have a plastic model. For a slightly larger investment I decided to purchase this kit and am glad I spent the extra money. It seems to be well made, pulls and holds a good vacuum, appears to be accurate and I expect it will be something that will work for many years to come. In addition the kit includes a variety of block off plates, silicone (I think) rubber adapters and block off plugs and a number of hose fittings and (2) ~16inch long sections of tubing. Due to the cast alloy material I would be somewhat hesitant to use this with anything corrosive to Zinc alloys as I suspect it would damage the metal. I have seen a number of scientific companies relabeling this product and selling it for a significantly higher price which is why I mentioned corrosive chemicals. Zinc alloys can reacts with both acids and bases so I would certainly avoid use with such chemicals. The included users manual details a wide range of automotive uses which I will certainly try out in the future. I have not used it beyond playing around with it to test it and attempting to vacuum test my Chainsaw case after installing new crank seals. I seem to have a major leak where I attempted to block off the intake manifold so I have not yet been able to successfully use it for its intended use. I do however believe it will work ideally for this use. It has a valve which allows you to switch between pressurization and vacuum action and the dial reads in both negative and positive ranges. It also has a pressure/vacuum release located under the selector valve. I am glad I made the extra investment in this product versus other makes and models of similar tools and believe it will be a good tool to have around for a variety of uses for a long time to come. If I were buying for scientific/lab use I would however consider the plastic version due to my previously stated suspicion that corrosives might seriously damage the item.

Siendo mityvac sólo se podía esperar calidad y es lo que ofrece. Cuerpo en aluminio maletín con accesorios todo de buena calidad. el reloj se puede girar en cualquier dirección. Lo único que tiene es una palanca por debajo del cuerpo para descargarla la cual es fácil de tocar sin querer y descargarla. Pero se puede quitar fácilmente.
