Crosslinked polyethylene tubing in CTS (copper tube size) ODs, designated by SDR rather than schedule. For CTS 5/8 we can publish the outside, but no wall yet — the wall values in our sources did not reach two independent confirmations, so we are not guessing the bore.
| Nominal | DN | OD (in) | OD (mm) | Wall series published |
|---|---|---|---|---|
| 5/8 | — | 0.750 | 19.050 | none — 1 designation(s) awaiting a second source |
Why the wall is missing. 1 designation(s) (9) appear in at least one source for this size, but not two independent ones. Unverified values are kept out of the published set on purpose — the rule.
Measuring this size
- Measure across the pipe, not the fitting: that is the OD, and it is the number a clamp, a hole saw or an insulation sleeve has to match.
- Measured
19.05± a fraction of a millimetre points at CTS 5/8. Check which standards a measurement fits — the same OD can belong to more than one. - The bore decides flow; the wall decides pressure rating and how deep a thread cuts. Neither number is in the name CTS 5/8 carries.
Questions about CTS 5/8
What is the outer diameter of CTS 5/8 pipe?
0.750 in / 19.05 mm Calipers measure this number; the name does not.
No edition year is claimed. These values match ASTM F876/F877 (CTS) as published by the sources above, but the specific printing was not verified, so the standard is named without a year.
