Can You Flare Hard Drawn Copper?

It is possible to flare Types K, L or M rigid or hard temper tube, though prior to flaring it is usually necessary to anneal the end of the tube to be flared. The copper tube must be cut square using an appropriate tubing cutter.

How do you connect hard copper to soft copper?

Hard copper tubing is typically joined together by soldering fittings onto the ends of the pipe or tube. You can seal joints with hard copper using a mechanical compression fitting. Soft copper can also be soldered, but many people chose to use mechanical flare or compression fittings that seal joints by pressure.

Can copper pipe be flared?

In theory, regular rigid copper pipe can be flared, but a soldered joint is much faster to make. Also, rigid copper is hard and likely to tear in the flaring process unless it's first annealed (heated with a torch and allowed to cool slowly).
