Is it ok to take apart a 2-handle faucet cartridge (Delta, Valley, etc) and put silicone lubricant on the inner stem and also on the inner o-ring that the stem goes thru? Or is it best to leave the innards alone and just lubricate the exterior o-ring and seat? I know the stem turns within this inner o-ring, but am not sure if the stem turns while the o-ring stays in place, or if turning the stem also turns this inner o-ring along with it, or does it matter. I was just concerned if I lube'd the o-ring and it's meant to be stationary during turns (i.e., the stem only turning within the o-ring), that this would cause it to slip around (turn) along with the stem unintentionally. I am probably over-thinking this, but wanted to ask. The primary motivation is to protect/lengthen the inner o-ring's life and ensure easy turning of stem, particularly on the hot water side. Note this is the small inner o-ring, not the larger one on the outside middle. TIA.
