Our productsStraight copper tubes
Straight copper tubes for HVAC, refrigeration and industrial fabrication inquiries. From outside diameter to final packing, define the details your project needs and request a quotation by specification.
01 / DIMENSIONS & TOLERANCES
Specify the tube your project needs.
The table lists actual outside diameters used in common ACR inquiries. Plumbing nominal sizes follow a different convention. Always state the actual OD, wall and governing standard.
| Actual OD · inch | Actual OD · mm |
|---|
| 1/4″ | 6.35 mm |
| 3/8″ | 9.52 mm |
| 1/2″ | 12.70 mm |
| 5/8″ | 15.88 mm |
| 3/4″ | 19.05 mm |
| 7/8″ | 22.22 mm |
| 1 1/8″ | 28.58 mm |
| 1 3/8″ | 34.93 mm |
| 1 1/2″ | 38.10 mm |
Outside diameter & wall thickness
State dimensions as outside diameter × wall thickness, in mm or inches. Include the minimum acceptable wall, any required internal diameter and the drawing revision. Wall thickness must be matched to the intended duty and standard.
Straight or cut lengths
Common industry references include 3 m, 5 m and 6 m straight lengths. Request the exact length, cut-length tolerance, end finish and bundle weight that suit your production and freight plan.
Agree the measurable requirements
- Diameter & wall: specify permitted OD variation, wall variation, minimum wall and ovality using the chosen standard or drawing.
- Straightness & ends: define straightness, cut squareness, burr removal, surface condition and end protection where relevant.
- Length & sampling: agree cut-length deviation, measurement methods, inspection sampling and batch identification before production.
Dimensions are inquiry references, not a stock list. Supply range, tolerances and application suitability are confirmed against the selected material, standard and order requirements.
