Carbon fibre tube sizes: pultruded and roll-wrapped, 0.7 to 60 mm OD — dimension sheet Source: Xem Studio, https://xemstudio.com/objects/carbon-fibre-tube-sizes/ (sheet CC BY 4.0) Basis: Maker's product listings (Easy Composites): OD and ID as printed in each title Catalog version: 2026-10-20 Sizes: see table below - Round carbon tube stock in the sizes one maker lists, OD and ID exactly as printed in each product title (OD first, ID in brackets). Wall = (OD − ID) / 2. Lengths offered: 1000 mm, most also 2000 mm. - Pultruded tubes are the small sizes (0.7 to 12 mm OD); roll-wrapped tubes run from 5 to 60 mm OD in plain and woven finish. The same OD can come with two IDs (10 × 8 and 10 × 9, 12 × 10 and 12 × 11, 25 × 22 and 25 × 23): check the ID before designing an insert. - Nesting: where one tube's nominal ID equals another's OD (6 × 4 in 8 × 6, 8 × 6 in 10 × 8, 10 × 8 in 12 × 10, 12 × 10 in 14 × 12, 14 × 12 in 16 × 14, 16 × 14 in 18 × 16, 18 × 16 in 20 × 18, 20 × 18 in 22 × 20) the pair is line-to-line at nominal size: check the real tolerance before relying on it as a slip fit. Tube tolerances are not on the maker's list pages. - Files: one 50 mm section per published OD × ID (true size, no clearance) to subtract from a clamp, socket or wing root, or to check a fit. - The two hexagon pultrusions (14 (12) and 16 (14)) are listed without saying whether the size is across flats or corners, so they have no file. type OD mm ID mm wall mm section pultruded 0.7 0.3 0.2 round pultruded 1.5 0.7 0.4 round pultruded 2 1 0.5 round pultruded 3 2 0.5 round pultruded 4 3 0.5 round pultruded 5 3 1 round pultruded 6 4 1 round pultruded 7 5 1 round pultruded 8 6 1 round pultruded 10 8 1 round pultruded 12 10 1 round roll-wrapped, plain (metric) 10 8 1 round roll-wrapped, plain (metric) 12 10 1 round roll-wrapped, plain (metric) 15 12 1.5 round roll-wrapped, plain (metric) 18 15 1.5 round roll-wrapped, plain (metric) 20 17 1.5 round roll-wrapped, plain (metric) 25 22 1.5 round roll-wrapped, plain (metric) 30 27 1.5 round roll-wrapped, plain (metric) 35 32 1.5 round roll-wrapped, plain (metric) 40 37 1.5 round roll-wrapped, plain (metric) 50 47 1.5 round roll-wrapped, woven finish 5 3 1 round roll-wrapped, woven finish 6 4 1 round roll-wrapped, woven finish 7 5 1 round roll-wrapped, woven finish 8 6 1 round roll-wrapped, woven finish 10 8 1 round roll-wrapped, woven finish 10 9 0.5 round roll-wrapped, woven finish 12 10 1 round roll-wrapped, woven finish 12 11 0.5 round roll-wrapped, woven finish 14 12 1 round roll-wrapped, woven finish 16 14 1 round roll-wrapped, woven finish 18 16 1 round roll-wrapped, woven finish 20 18 1 round roll-wrapped, woven finish 22 20 1 round roll-wrapped, woven finish 25 22 1.5 round roll-wrapped, woven finish 25 23 1 round roll-wrapped, woven finish 30 27 1.5 round roll-wrapped, woven finish 40 37 1.5 round roll-wrapped, woven finish 50 47 1.5 round roll-wrapped, woven finish 60 57 1.5 round pultruded 14 12 — hexagon (whether the size is across flats or corners is not stated) pultruded 16 14 — hexagon (whether the size is across flats or corners is not stated) Files elsewhere (not hosted by Xem Studio; license as stated by the publisher): - Easy Composites: Pultruded carbon fibre tube (category: OD and ID in each product title) — web — Publisher's page; dimensions are facts — https://www.easycomposites.co.uk/pultruded-carbon-fibre-tube - Easy Composites: Plain finish roll wrapped carbon fibre tubes, metric (OD and ID in each title) — web — Publisher's page; dimensions are facts — https://www.easycomposites.co.uk/roll-wrapped-carbon-fibre-tube-metric - Easy Composites: Woven finish roll wrapped carbon fibre tubes (OD and ID in each title) — web — Publisher's page; dimensions are facts — https://www.easycomposites.co.uk/woven-finish-carbon-fibre-tube - Easy Composites: 5mm (3mm) pultruded carbon fibre tube (OD 5, ID 3, wall 1 mm) — web — Publisher's page; dimensions are facts — https://www.easycomposites.co.uk/5mm-pultruded-carbon-fibre-tube - Easy Composites: Technical datasheet: carbon fibre pultrusions (tube, rod, strip, box section sizes) — web — Publisher's page; dimensions are facts — https://media.easycomposites.eu/datasheets/EC-TDS-Carbon-Fibre-Pultrusions.pdf Free files (CC BY 4.0, Xem Studio; STEP + STL, 28 parts): https://xemstudio.com/files/hardware/carbon-fibre-tube-sizes/index.json API: https://xemstudio.com/api/geometry?object=carbon-fibre-tube-sizes
