5mm Carbon Fiber Tube 500/1000mm | ID 3mm | 3K Glossy Plain | HaoZhong

Roll-wrapped carbon fiber tube measuring 5 mm outside and 3 mm inside, which puts the wall at 1 mm. The 3K plain weave runs straight along the length under a high-gloss finish, so the surface reads clean next to machined fittings. Two lengths are listed: 500 mm and 1000 mm.

• Outside diameter: 5 mm
• Inside diameter: 3 mm, giving a 1 mm wall
• Lengths: 500 mm and 1000 mm
• Weave and finish: 3K plain, glossy
• Pack options: 1 pcs, 2 pcs, 5 pcs

A tube this small is usually a pushrod, an antenna sleeve or a spar in a micro airframe, where a 3 mm rod or insert needs to slide in without play.

Both 500 mm and 1000 mm are standard. Longer pieces and intermediate bores are priced on request, and custom sizes start at 10 pcs.
