Plastic Reservoir

Glass Reservoir


Wherever a fluid is to be kept at a certain level. Most popular use is for lubricating bearings. However, it has proven, too, as a reservoir for quenching mechanical seals and other applications. The combination of stainless steel with PTFE gaskets allows even aggressive fluids to be used.


The plastic reservoir is interchangeable with the one from glass. Details see Oil-Watch Type F.
