Using for some low pressure food grade steam and they are handling it like a champ. Just remember to write the size on the little ziplock they come in since they are otherwise unlabeled.

The orings in the "rebuild" kit was too thin and the reservoir comtinued to slowly leak out the fluid. I saw that these are rated for higher temperatures and are just a tad bit thicker but the same I.D. and O.D. I could really tell the difference when installing and now no more puddles on the drive!
