all stopcocks and moveable joints in a vacuum system must be satisfactorily lubricated while remaining leak proof. The ideal lubricant for this purpose would have a low vapor pressure and be stable, chemically inert, non-toxic, and easily applied/removed. Apiezon greases have these qualities. A wide range of greases are available for various applications. Product vapor pressure @ 20? C (torr) melting pt. (? C) average molecular weight specific gravity @ 20?
