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

The Mityvac MV8500 is a great buy. It works exactly as expected and makes brake and clutch bleeding much easier. It’s also very convenient and easy to take around, which is perfect if you’re working in different areas or need something portable. Solid quality tool and definitely worth the purchase.

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.

Paid for itself the first time I used it — at least in terms of saved aggravation if not outright prevented equipment damage. I replaced a cylinder on my chainsaw and (per the manual) did a quick pressure test and found a small leak in one of the fuel input channels. Which would have made the saw run lean and hotter, and quite possibly have eventually destroyed it. Fixed the leak, re-tested the pressure and now the saw runs like new. This kit is well worth the money. Great assortment of accessories and a decent (plastic) storage case. Easy to use for testing pressure and/or vacuum. Wish I would have purchased one years ago. I actually did buy a Mityvac vacuum tester (I think before the dual pressure/vacuum model was available) which still works great, so I am fairly certain the newer model will be just as reliable.

Works great. Quality build. Reasonable price. Fast delivery. Spare parts available. I would buy again. YOU NEED THIS!!

I used this to bleed brakes and change the fluid. Like any of these, it seems none of the adapters fit tight enough to prevent any air from entering, but it worked well and wasn't overly fatiguing to do all for wheels. I think it might work better on vacuum hoses. A bit pricier than some other options, but I think it was worth it for the variety and all the options it provides.

Very satisfied with the quality and versatility of this tool. You may find a cheap knockoff but you get what you pay for. If quality and reliability and safety are important to you and you'll be using it more than once get this one

Well worth the upgrade over the plastic version! when purchased, it was 30 percent more than the consumer level model. While the 20 year old plastic Mityvac this replaces still works, the gauge lens had cracked, and the plastic seems to ooze brake fluid like the creature in a Stephen King novel. The weight, feel, and solidity feels like a tool rather than a toy phaser or Nerf projectile launcher, it is satisfying to hold and use. The plastic version seems to get and stay extra slippery while this, the metal version, doesn't seem to get as unwieldy. The gauge is armored like you might find on Navy Seal level scuba gear, but we know mechanics are tougher on gear and have a smaller budget than The Seals. The kit includes some useful accessories but the mind bogglingly 'cost effective,' master cylinder adapters should be used to make a spirograph, rather than being used anywhere near paint removing brake fluid. The company history leads me to believe that rebuild kits will be available longer than I'll be around to use it. Made in China? Well, isn't everything including a majority of the stuff that comes off the tool truck? The quality control and company behind the name make this a no-brainer. I could afford a similar product if one were made in the US, but it probably wouldn't have the same long term dependability and support as the Mityvac. The included molded case is the usual will look good collecting dust in your tool box and 'it all fit in there when it left the factory, but once unpacked, good luck on making it ever fit again,' even after removing the plastic bags. The case ONLY holds what was included, no room for more hose, the fittings from your old Mityvac or one of the accessory large catch bottles. The only complaint is that once the hose has been attached to the pump, it is nearly impossible to remove, which snowballs to making it so the pump won't fit back in the molded case. Easy fix? Replace the straight barb with a 90 degree elbow with or without barb right? Fantastic plan if you have access to 1/16" brass ( unknown thread pitch so far) fittings, but for us regular people.

This is high quality and worked great!

Very impressed with this unit, I bought strictly for vacuum testing rebuild engines but I’ve found many more uses. The quality better than I expected. The amount of accessories is great for just about any job you’d do with this tool. I’ve had about 3 cheaper ones that cost a fraction of the cost, all of them failed to some degree, this was 100% worth it for the quality and usage. Spend the money now, or you’ll spend more later.

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.

Arrived in good time and condition. Seems to function as described.

I like it. It's very good.
