A 3/4″ thread seal is a type of thread seal that is used to prevent leaks in threaded connections. It is typically made of a soft material, such as PTFE (polytetrafluoroethylene), that is compressed when the connection is tightened. This creates a seal that prevents fluids from leaking out of the connection.
PTFE thread seal tape is the most common type of 3/4″ thread seal. It is made of a slippery, non-stick material that is resistant to chemicals and temperature extremes. It is easy to use and can be applied to both male and female threads.
