Klister valve
From Tardis Wiki, the free Doctor Who reference
A klister valve was a component of a TARDIS essential for moving the ship. Klister valves required magnatite to function.
On Tiro, the First Doctor discovered that one of his klister valves had run out of magnatite, forcing him to get some more from Argon. (PROSE: Terror on Tiro [+]Loading...["Terror on Tiro (short story)"])
