One aspect of the disclosure relates to a sliding member. The sliding member includes: a first sliding portion having a first lubricant placed between first parts of a first friction sliding mechanism; and a second sliding portion having a second lubricant placed between second parts of a second friction sliding mechanism. The first sliding portion has a lubricant feed port from which the first lubricant is fed, and the second sliding portion has no lubricant feed port from which the second lubricant is fed. The first lubricant contains base oil and an additive. The second lubricant contains base oil and an additive containing conductive carbon. The second lubricant contains a relatively larger amount of conductive carbon than the first lubricant.

A grease composition includes a base oil, a thickener, and an additive. The base oil is at least one selected from the group consisting of polyoxyalkylene, ether derivatives of polyoxyalkylene, and mixtures thereof. The additive includes polytetrafluoroethylene as a first solid lubricant and at least one selected from the group consisting of calcium carbonate, calcium oxide, tricalcium phosphate, and calcium salts of fatty acids as a second solid lubricant. The content of the second solid lubricant is 0.5% by mass or more based on the total mass of the composition.

The present invention describes a pipe sealing compound/adjunct lubricant used to prevent gas or liquid leaks when applied to pipe threads and other connections of the same. The compound relies on silicone oil lubricant(s) and one or more friction modifier(s), viscosity builder(s) and filler material(s). The compound contains a viscoelastic liquid that does not have a curing phase and is resistant to hardening and/or drying. The compound is chemically resistant to a wide variety of liquids and gases, is food safe and can withstand extreme high or low temperatures and precipitous temperature fluctuations. The compound has been found to exhibit an inverse pressure to leak rate phenomena.

The present disclosure relates to an automotive slide member including a first slide portion having a first lubricant applied between first portions of a first friction slide mechanism, and a second slide portion having a second lubricant applied between second portions of a second friction slide mechanism. The first slide portion is arranged at a part to be touched by an operator who attaches the automotive slide member to an automobile or a user of the automobile. The second slide portion is arranged at a part that is not touched by the operator who attaches the automotive slide member to the automobile or the user of the automobile. The second lubricant contains a relatively larger amount of conductive carbon than that of the first lubricant.
