Inverted Flare

  • Typical Application
    Hydraulic brake, power steering, fuel lines and transmission cooler lines, LP and natural gas.
  • Working Pressure Ranges
    Temperature and type of tubing used are important factors. However, the following table is a good guide for proper selection. Temperature 730F with copper tubing:

  • Vibration
    Excellent resistance.
  • Temperature Range
    -65°F to +250°F (-53°C to +121°C) range at maximum operating pressures.
  • Material
    CA360 Brass.
  • Used With
    Copper, brass, aluminum and steel hydraulic tubing that can be flared.
  • Advantages
    Very low cost and reusable. Seats and threads are internal and protected. Compact, excellent vibration life. Short nut affords very close tube bends. Steel or brass tube nut.
  • Tolerance
    +/- .03 on all dimensions. Dimension data can change without notice. Please contact us when dimensions are critical.
  • Conformance
    Meets specifications and standards of ASA, ASME, SAE and MS (Military Standards).
Assembly Instructions
  1. Cut tubing to desired length. Make sure all burrs are removed and ends are cut square.
  2. Slide nut on tube. Threaded end of nut must face out.
  3. Flare end of tube with a 45° flaring tool.
    a-Measure flare diameter.
    b-Examine flare for excessive thin out.
    c-On thin wall, welded or brazed tubing, use double flare to prevent pinch-off and cracked flares.
  4. Lubricate threads and assemble to fitting body. Nut should be turned hand tight.
  5. Tighten assembly with wrench until a solid feeling is encountered. From that point, apply a one-sixth turn.

    Note: Do not over-torque as it may damage the
    fitting or split the tubing at the flare.
