   For example, DN20 is the size for copper pipe with an outside diameter of 19.05 mm or 3 ⁄ 4 inch. While pipe sizes in Australia are inch-based, they are classified by outside rather than inside diameter (e.g., a nominal 3 ⁄ 4 inch copper pipe in Australia has measured diameters of 0.750 inches outside and 0.638 inches inside, whereas a ...

5. Pipe insulation - Wikipedia

   en.wikipedia.org/wiki/Pipe_insulation

   Polyethylene is a flexible plastic foamed insulation that is widely used to prevent freezing of domestic water supply pipes and to reduce heat loss from domestic heating pipes. The fire performance of Polyethylene is typically 25/50 E84 compliant up to 1" thickness.

6. Push-to-pull compression fittings - Wikipedia

   en.wikipedia.org/wiki/Push-to-pull_compression...

   A push-in compression coupling and tee. Push-to-pull, push-to-connect, push-in, push-fit, or instant fittings are a type of easily removed compression fitting or quick connect fitting that allows an air (or water) line to be attached, nominally without the use of tools (a tool is still usually required for cutting tubing to length and removal).

7. Thread seal tape - Wikipedia

   en.wikipedia.org/wiki/Thread_seal_tape

   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. The tape is sold cut to specific widths and wound on a spool, making it easy to wind around pipe threads. Thread seal tape lubricates, allowing for a deeper seating of the ...
