Behold Teleios sleeve. The top choice for any level of sleever since 2013.

Months of development went into crafting the ideal sleeve for beginners just getting into the hobby, to professionals who demand the utmost quality to reflect their project. Teleios sleeve embodies the core components needed to achieve this feat.

Tight PET Filament Weave

To start, PET filaments are tightly wound together to create its circular shape. So tight that it is very difficult to see through the material without it even being stretched. This creates a natural barrier from being able to see the wire underneath the sleeve which is the main goal when sleeving your cables. Furthermore, the sleeve holds its tight weave even when the sleeve is bent, or for example placed around sharp corners. Other sleeve types will fray apart unveiling the wire underneath especially those of larger diameters. We developed Teleios sleeve with this in mind and found 4mm is the perfect blend of size and pliability.

Easy to Use

What makes a sleeve great if it is not easy to use? A great sleeve needs to be easy to use. This implies that beginners will not have issues using the sleeve, or that the technique can be picked up easily. Both of which Teleios sleeve delivers on. Some sleeve types are catered towards the more experienced leaving the beginners feeling frustrated and eventually give up. Sleeving with Teleios is as easy as pulling the sleeve over the wire, and melt.

Industry Standard

Teleios sleeve has been used alongside some of the industry leading technology companies in the world to showcase their new products. From NVIDIA to award winning producers such as Deadmau5 to name a few, Teleios sleeve was used in sleeving the power supplies that powered their new tech. We have been fortunate to be brought alongside in creating these beautifully crafted cables for their projects many of which can be found all over the internet.

Other names include:

  • NVIDIA GeForce Garage
  • Intel
  • EK Water Blocks
  • Jayztwocents
  • Pualshardware
  • Bitwit
  • and more..

To Stretch, or Not to Stretch?

Without a doubt what makes Teleios sleeve so easy to sleeve with is its ability to deliver great coverage on a wire with, or without stretching the sleeve much at all. There are not many if any other sleeve types out there that give you this ability. This plays an important role when measuring, and ultimately melting the sleeve to the wire. Other sleeve types tend to need to be stretched in order for the PET filaments to close together. This becomes an issue when the user must then hold the sleeve while trying to melt the ends of the sleeve to the wire. The sleeve will then try to pull back from the sleever making it difficult to melt properly and ultimately giving you undesirable results. Teleios sleeve is easy to stretch if you would like and if so doesn’t need to be stretched much to give you an unsurpassed level of coverage over your wire.

Low Melting Temperature

Another ingredient to give you professional results? Having a low melting temperature. A low melting temperature means that the sleeve will melt at a low temperature, or doesn’t need a long time over a flame to melt. What does this mean to you as a sleever? An easier to sleeve to control and be able to tack to the wire without issues. Sleeving that requires long melting times tend to burn and discolor which ultimately render the sleeve unusable. Vice-versa have a sleeve that has too low of a melting temperature and has it melt too fast making it difficult to control. We developed Teleios sleeve to have best of both worlds, a low melting temperature that is easy to control. However, that is not to say that Teleios sleeve will melt when over your wire. Teleios sleeve is very robust and can withstand high temperatures within an environment. This is just in the sleeving process when a flame is needed to melt the ends on the wire.

Whether you are just getting into the hobby or already an avid sleever, Teleios sleeve makes it easy to achieve the finishing touches to your computer that make it stand out above the rest.

    Beautiful Sleeving!Great coverage, shiny and melts well for shrinkless sleeving. I used the black and navy blue for a subtle sleeve job; couldn't be happier!

    The right stuffThere are no cons about this sleeving that I can think of. A solid (almost literally) sleeve to hide any unsightly wires in your build. It's not quite a pliable as the navy blue I also used, but it gets the job done and does it well.

    Great looking sleevingThis is a real deep black colour and there are no holes - it's a solid sleeving with a solid colour. With the correct heatshrink this sleeving melts perfectly. It's made modding a whole lot easier!

    Very very nice sleeving ! The black color is very clean and looks great ! It melts very quickly (with a lighter) so it makes it easier to make heatshrinkless sleeving (given that the heatshrink doesn't melt as fast as this sleeving does).

    This sleeving is great. This is my first sleeving job and I have had no issues using this sleeving and it is making my computer project really stand out! Easy to stretch out and keeps a nice tight fit to the cable. i am using 16awg wire along with having no issues training the cables to have that nice arc! Thank you Mainframecustoms for having an awesome product that is going to take my computer ascetics to the next level!

    This sleeving is ridiculously easy to work with and the density is great. Multi-colored wires inside do not show through. You just get the sleeve color you want, no fuss!

    Bold, vivid color. Dense weaving. Easy to work with. LC Teleios checks all the boxes on the list of things I look for in a sleeving. I can't say I've worked with any other PET-based sleeving, but I honestly can't imagine anything nicer. It's a little stiff and has a nice springy feel to it, which helps when expanding it over a connector or stretching it taut along the length of a wire. Works well with the heatshrinkless style, haven't tried it with the heatshrink style. Using a bit of heatshrink to melt the end onto a terminal in heatshrinkless results in a beautiful melted cone. I've also managed to melt it without heatshrink by just tacking it down to the terminal with my fingers, but this is much more difficult because the sleeving tends to expand outwards when melted and never results in as nice of a bond.

    If you're not using paracord and want a quality sleeve, LC Teleios is the way to go.
