Carbon fiber-Kevlar tube with mesh view, made entirely with high quality carbon-kevlar fiber.

Manufactured in 1.5 mm thickness. and with a special distribution of carbon-kevlar fibers, is thinking to provide maximum rigidity to spearfishing spearguns, minimizing the flexions caused by the tension of the tires.

It is real carbon-kevlar fiber, pressed and cured in the oven, with an outer layer of Carbon Fiber-Kevlar that provides extra resistance to impacts and friction with rocks by only 1 gr. more weight per 10 cm. in length than the 100% carbon tube. With constant thickness, very high hardness and very little weight.

Nothing to do with other tubes that use mixtures of carbon and glass or poorer buildings, which of course are cheaper but not at all so rigid.

If you need a tube with other lengths, diameters or thicknesses, do not hesitate to contact us, we can manufacture it.

We can manufacture the same tube with 1 mm wall. If you are looking for lightness or also in 2 mm. if you wish


  • Length: From 600 to 1200mm. (Tolerance ± 10mm.)

  • Outside diameter: 28mm. (Tolerance ± 0.2mm.)

  • Internal diameter: 25mm. (Tolerance ± 0.2mm.)

  • Wall: 1.5mm. (Tolerance ± 0.2mm.)

  • Weight: 20gr for every 10 cm. of length (Tolerance ± 5gr.)

  • Resistant to heat (Thermal stability 180º)

  • Degree of flexibility for this thickness: Very low (Null)

  • Carbon fiber: 3K 200 gr / m2 Fabric Twill 2x2 (Twill)

  • Orientation of the fibers: Bidirectional

Since these tubes are made of 100% carbon fiber, and with a very constant thickness, they are perfect for precision or structural work.

Ideal for underwater fishing rifles, paddles and paddles, hand brakes, etc.


All our tubes admit a certain tolerance in their measurements, this comes from the necessary cuts and the manufacturing process itself. They can then present in some cases irregular edges that in no case affect the quality of them, but if the size.
Although we always try to send our tubes with a size equal to or greater than the one offered, which we do in 90% of cases, remember that there is a reasonable margin for which we will not accept claims.
For this reason, and to avoid misunderstandings, if you need an extremely precise tube in the cut or size, do not hesitate to let us know at the time of placing your order so we can take it into account.
