Thread seal tape is wrapped around the threads, lubricating the connection and allowing the two pieces to be screwed deeper together. Thread seal tape (also known as PTFE tape, Teflon tape, or plumber's tape) is a polytetrafluoroethylene (PTFE) film tape commonly used in plumbing for sealing pipe threads.
Self-amalgamating tape is a non-tacky silicone rubber tape that when stretched and wrapped around cables, electrical joints, hoses, and pipes combines or unites itself into a strong, seamless, rubbery, waterproof, and electrically insulating layer. [1] [2] Unlike many other polymers and fibers, it is heat-, sunlight-, and weather-resistant.
Petroleum-based pipe dope is not intended for use on threaded PVC, CPVC or ABS pipe and fittings since it will deteriorate the plastic. Builders in the US are expected to use thread compounds that meet ASTM F2331 - Standard Test Method for Determining Chemical Compatibility of Thread Sealants with Thermoplastic Threaded Pipe and Fittings Materials or thread seal tape on PVC, CPVC and ABS threads.
Steel pipe is often joined with threaded connections; tapered threads are cut into the end of the pipe, and sealant is applied in the form of thread-sealing compound or thread seal tape (also known as PTFE or Teflon tape) and the pipe is screwed into a threaded fitting with a pipe wrench.

In case of an internal leak, water will overflow through the external piping and can be detected inside the cabinet. A pipe-in-pipe system [1] is a form of plumbing where all water pipes are running inside another pipe. Its purpose is to ensure that any leaks ...

The blue plastic disks seal against the inside of the pipe to propel the device and to remove loose sedimentation or scale buildup. The black rectangles at the top and the circular disks in the center are magnets to attract and remove any loose metal objects in the pipe. An ultrasonic leak-detection pig.
