Vintage 1950s New Britain FT-12 Double Flaring Toolkit

1950s Vintage New Britain Hand Tools FT-12 Double Flaring Tool Kit in its original red metal case. This specialized mechanical tool set is used primarily in automotive and plumbing work to create secure, leak-proof double flare connections on thin-walled metal tubing like copper, aluminum, or soft steel brake lines.

Key Components of the KitFlaring Bar Assembly: The long, split metal bar at the bottom with multiple sized holes. It clamps securely around the tubing to hold it firmly in place during the flaring process.Yoke and Screw Assembly: The large, heavy-duty U-shaped clamp with a threaded forcing screw and a swivel cone. It fits over the flaring bar to apply downward mechanical pressure.Wing Nuts: Two large heavy-duty wing nuts used to tightly clamp the flaring bar segments together around the tubing.Flaring Adapters: The five small, circular metal discs stored in the upper right compartments. Each adapter corresponds to a specific tube outer diameter (O.D.) ranging from 3/16" to 1/2". They are essential for performing the first stage of a double flare by folding the tube inward.
