Most Unusual ............................
.................... that you have some "unknown" packing that requires annual lubrication.
Many (maybe even most) packings today contain teflon in either solid or a well dispersed form in synthetic fibres. These materials do not need lubrication for the life of the packing.
If you ARE obsessed with lubricating the packing, the WM Syntef is a good lubricant but there are much cheaper (and equally as good) lubricants such as Super Lube.
Either way, a waste of time and money :cry: .
