per Feet (USD)Techflex Carbon Fiber Braided Sleeve, 3/4" Nominal, Black, Sold by the Foot
Real biaxial carbon fiber braid: expands over hoses, tubes and harnesses for a genuine carbon fiber finish, and can be resin-set into a light, rigid tube.
Techflex Carbon Fiber is a tightly braided, biaxial carbon fiber sleeve. Racetronix is a Techflex distributor. It expands over hoses, harnesses and tubes to dress them in genuine carbon fiber, and, like any carbon braid, it can be wet out with resin to make a light, stiff, seamless tube that can be cut, drilled, sanded and painted or left with the weave showing. This is the 3/4" size; it expands from 5/16" to 7/8". Sold by the foot.
Key features
- Genuine carbon fiber, not a printed or plastic look-alike.
- Expands from 5/16" to 7/8" to slide over fittings and connectors.
- Thin 0.013" wall and very light.
- Can be laid up with resin into rigid, seamless tubes up to 3" across.
- Carbon fiber conducts electricity: use it over insulated wiring and hoses, never over bare terminals or splices.
- The maker publishes no heat rating, so it is a dress-up and abrasion cover, not heat protection.
Which size fits?
This size suits: -8 rubber; -10 rubber; -10 PTFE; -12 PTFE; -6 push-lock; -8 push-lock; 5/8" hard line.
Choose the size whose expansion range covers the outside of your hose or bundle, and which will open up enough to pass over any fitting or connector it has to slide over. The braid gets shorter as it expands, so cut it longer than the run.
Hose outside diameters are nominal values from our own hose pages. Measure your hose if in doubt.

Fitting the carbon fiber sleeve
- Wrap a turn of tape around the braid where you will cut, then cut through the tape with sharp scissors. The tape stops the end fraying.
- Push the braid along to open it up and slide it over the hose, tube or harness.
- Pull it straight to tighten it down onto the line.
- Finish the ends with heat shrink or a clamp.
- For a rigid tube, slide it over a waxed or release-coated mandrel and wet it out with laminating epoxy, then cure, slide off and finish.
Frequently asked questions
Is it heat protection?
No heat rating is published for it, so treat it as a dress-up and abrasion cover. For heat, see FireFlex fire sleeve or T6 ThermaShield.
Can I use it over wiring?
Over insulated wire, yes. Carbon fiber conducts electricity, so keep it away from bare terminals, splices and battery posts.
Can I make a rigid tube from it?
Yes. Laid up with epoxy over a mandrel, it cures into a light, stiff, seamless tube up to 3" across that can be cut, drilled, sanded and painted.
Ratings are the maker's published figures.
