as you can see it has a solid aluminum piston with a Teflon o ring, that makes a tight seal in the cylinder and there was 0 meat blow by ,
.the gears are industrial grade cast steel ,
the gears are dry and make a tiny bit of noise when cranked ( I plan on buying a food grade grease to lube them . then they should be quiet and smooth as silk )
, everything comes apart , making clean up a breeze ,
the ONLY thing I would be concerned about would be the Teflon O ring ( I am going to order a couple of extras just in case I break one while taking it off to clean it and the groove , that's the only weak point I have found . and I think that could be replaced with a rubber O ring if you wanted to so its really not a biggie
let me know what you think
