What happens if you over tighten a compression fitting?
If the pipe is clean and cut properly, compression fittings work well. In the trade, it’s said to not over tighten a compression fitting, leaving you more thread in the case of a leak. After hand tightening a nut will need one whole turn.
Which is better solder or compression fitting?
Compression fittings are not nearly as robust as soldered fittings making them much more sensitive to powerful stresses. They are not ideal for applications where they could be potentially exposed to lots of flexing, bending and excessive vibration or tube movement.
Do compression fittings work on copper?
Compression fittings in the world of plumbing are very common. They are a safe way to connect copper pipe without the use of heat making them popular with DIY’ers. Many different types of valves, tees, connectors and utilities require compression fittings in order to make them water tight and safe.
What does SPG mean in plumbing?
