teflon tape or threadlock is not needed; just normal copper grease or white grease. you just need to crank on the lockring. you can probably put a bit more pressure on the cups, than say a headset ie easy rotating. as when you put the cranks on you won't tell the difference (sealed BB are also harder to turn than a headset ;) ). i learnt this the hard way with 2 similar BB's.
