Flare fittings should be used in
situations where they won't be
hidden within a wall.

About this Project

Flare fittings, like compression fittings, are useful in places where it's difficult to solder a joint. Do not hide flare fittings inside a wall. You can use flare fittings only with flexible copper tubing; they cannot be used on rigid pipe. Unlike compression fittings, this type of fitting requires a flaring tool. The two-piece tool reshapes the end of the copper tubing, "flaring" it to fit into a special flare fitting. If possible, make the flared connection first, then cut the tubing to length because sometimes tubing splits while being flared.
