Online Builder Hangout – April 2015

Our April Online Builder Hangout focused on proper tube flaring techniques and tool use. Check it out below.

  • Using the Parker Rolo Flare tool. Purpose of flare fittings, cautions in tube flaring.
  • Link to the tool:…
  • Question on how tight to torque flare nuts, see:…
  • Question of single vs. double flare. DOT/FAA Airframe & Powerplant Mechanics Handbook states: “A double flare should be used on 5052-O and 6061-T aluminum alloy tubing for all sizes 1/8″ to 3/8″ O.D. This is necessary to prevent cutting off the flare and failure of the tube assembly under operating pressures.”
  • To the question of hard vs. flex tube lines…As expected flex tube is used where movement is possible.

Also, sign up today for the May Hangout.
