flared joint

flared joint

A mechanical joint between two pieces of copper or plastic tubing; made by flaring one end of a tube in such a way as to receive a special fitting which fits in the flare; may be taken apart and reassembled without difficulty; especially useful in areas where fire hazard will not permit the open flame required in soldering or brazing a joint.
