Often referred to as a plumber’s best friend, Teflon tape or thread sealant is a simple yet effective material found in tradie toolkits worldwide. Also known generically as PTFE tape, it’s generally used as a sealant and lubricating material, perfect for installing fittings in the kitchen and bathroom.
When should you not use Teflon tape?
An important thing to remember is that PTFE tape should not be used when connecting PVC fittings or valves with a female (FPT) thread. If the tape is used on female connections, a wedging action can occur which will cause major stress on the joint during assembly. PTFE tape does not guarantee a leak free connection.
Does Teflon tape stop leaks?
Teflon tape will help prevent plumbing leaks. Teflon tape is an absolute essential for most plumbing projects. Its physical composition allows it to fill pipe threads and fitting threads with a sealant that will prevent water from leaking through the thread connection.
Is Teflon tape always necessary?
Seal plastic fittings by wrapping the thread with Teflon tape. Go around the fitting two or three times, then pull the tape tight to break it off. If a straight threaded connection has a rubber gasket, there’s no need to apply pipe sealant or Teflon tape.
How many times do you wrap Teflon tape?
You always want to wrap seal tape around threaded pipe fitting in a clockwise direction. In most cases for a new joint you should apply only two or three wraps of tape. On older fitting where the threads may be damaged you may consider adding a few more wraps, but keep the number of warps to a minimum.
Can you use Teflon tape on garden hose?

What did plumbers use before Teflon tape?
Pipe Dope. Pipe dope, also referred to as pipe joint sealant/compound, is a form of liquid used in sealing threads just like tape. The container comes with a cap that has a swab brush attached to it. The brush is used for applying pipe dope on pipe threads before attaching the fitting.

Why does my garden hose always leak?
