Tube adapters: matching tube to joint

You need three numbers: tube outside diameter, wall thickness, and joint thread size.

  1. Measure the OUTSIDE diameter of your tubing (for example 2.0").
  2. Measure the WALL thickness (for example .25").
  3. Know the thread of your joint (for example 1.25"-12, left or right hand).
  4. Pick the adapter that matches all three. Example: TA-247-1 = 1.25" hex adapter for 1.5" ID / 2.0" OD tube (RH).
  5. Install PDF: see 'Tube Adapter Installation Instructions' in our Installation Instructions articles.
