These very high viscosities mean the oils are well suited for rotary glands in particular, a type of seal where the turning shaft protrudes through the inner diameter of the O-ring.

These oils are designed for use wherever a high viscosity oil is needed for sealing purposes. With low vapour pressures, these products can be used with confidence under vacuum environments and can provide an effective vacuum seal. The main difference between the two products is in the higher viscosity of K oil compared to J oil; if a thicker oil is needed then K oil is the preferred choice.
These oils could also be used to seal fragile glassware in vibrational applications; however they are liquid and should only be used in applications where the oil would have nowhere to flow to. We also offer a range of waxes which can be used in vibrational applications.
