It is well made, and pulled and held 25 inches of vacuum, though it took lots of pumping, and with a few drops of oil it pulled 27 inches, but that really wore me out, overall it is well worth the money, it's almost all solid steel/brass and quite well made, perfect for degassing silicone and various science experiments. Also 25 in/hg of vacuum is roughly equal to 60,000 feet altitude, so it is capable of making marshmallows grow, or for vacuum canning dry goods, also comes.

Works well with the jar sealer lids also advertised here. I take the seal down to 20 which is equivalent to the Food Saver, but it's tiring on your hands. I can only do two jars at a time, and that's with using both hands so you need to plan ahead and space out the jars. If you have a large quantity to seal, you might want to consider an electric pump and keep this as a backup.

Actron CP7830 Replacement Vacuum Pump for Henry Milker for Goats.
We purchased a Henry Milker to relieve excess pressure in a goat's udder after she had her kids.
The Actron hand pump replaced the plastic MightyVac pump shipped with the milker when its handle broke after 4 months milking 2 does.
This hand vacuum pump is robust, effective and well worth the couple extra dollars to the frugal goat person.

I ordered this to draw brake fluid from wheel cylinders into a jar. I had drilled
holes in the jar lid and installed rubber grommets through which I passed flexible
tubes. My master cylinder has a screen and valve assembly under the filler cap.
So, instead of trying to remove the assembly, I pumped all of the fluid out through
the wheel cylinders, refilled the master reservoir and used the pump to flush out
as much of the old fluid as possible, while repeatedly topping off the reservoir.
