Not a good choice for hose connections, Keith. You don't want to use
any lubricant that provides any lasting lubrication, 'cuz that can allow
the hose to work its way off the fitting. The only type of lubrication
that should be used on hose connections is one that's water soluble, and
therefore dries out and ceases to provide any lubrication very
quickly...dish soap or K-Y surgical jelly.

Otoh, pump parts that are "under water" for long periods require a
lubricant that doesn't dissolve in water easily, is thick enough to
provide protection against friction for a season or longer, and doesn't
have any petroleum products in it to degrade rubber...that's teflon
grease. Metal-to-metal parts require yet a different type of lubricant.

So the same is true of lubricants that's also true of sealants--there is
no "one size fits all" applications...you have to use the right one for
the particular job.
