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