Anarchism is a philosophy that embodies many diverse attitudes, tendencies and schools of thought; as such, disagreement over questions of values, ideology and tactics is common. The compatibility of capitalism, nationalism, and religion with anarchism is widely disputed.
I should have been more clear. The systems where I typically see Teflon used are water systems (either automotive or household plumbing) and pneumatic systems where the tape is used on a tapered male thread. In those cases, the male thread could be tightened without the Teflon tape, in many cases without leaks.
Connections that rely on threaded pipes and fittings are prone to leaks if they're not sealed with either Teflon tape or Teflon pipe joint compound. Careful plumbers use both on every joint for extra security. They don't want to come back. Start by wrapping the male threads with Teflon tape (Photo 1).
