How to choose
- Size by tube OD: compression fittings are sized by the tube’s outside diameter (1/8 to 5/8 in. and up), not pipe size; the pipe-thread end is sized in NPT.
- Sleeve material: brass sleeves are for copper and metal tube; Delrin (plastic) sleeves suit plastic tubing.
- Use an insert: soft plastic tubing usually needs a tube insert so it doesn’t collapse under the sleeve.
- Lead free: choose lead-free fittings for potable water lines.
- Don’t over-tighten: tighten finger-tight plus the turn the maker recommends; replace the sleeve if the joint is remade on new tube.
