I'm going to be replacing a tub/shower (leaking) Diverter Spindle and Flow Control Spindle washers, packing nut, etc. Should I apply Plumbing Grease to any of these parts when I install them?
The only fixture that I know of that calls their stems spindles are Symmons.
a little grease on the stem threads is okay. nothing on or in the balance spindle part of the unit.
Just a touch of lube on the diverter o-ring.
Silicone lube recommended due to plastic parts.
Had trouble with that particular diverter. Had to double up on the O-rings
