Looks like heat shrink to me!

What is the difference between Sleev and standard shrink tubing?

The main differences between Sleev and standard heat shrink include the quality. The quality of standard heat shrink is generally lower as compared to that of Sleev. Also, once Sleev is placed on the wire, the center is rigid while the ends remain flexible, allowing for free movement while protecting the integrity of your wire. This free movement is possible because of the several different shrink ratios found throughout Sleev, which is not found in standard heat shrink.

Kickstarter: Sleev

360% Funded!!!

    I don't trust anyone who can't spell sleev or strech.

    Four bucks for 2 pieces of heat shrink. Give me a break! Unless there is something magical about this product.

    Yes, one born every day. :)

    Don't use Sleev on anything you're building for NASA. They require transparent heat shrink tubing.

    This is one of the most absurd KickStarters I've seen.

    I now use all those standards myself when bulding: (Thanks for the link)

    I've been using transparent heat shrink for several years, Now normal heatshrink looks barbaric.

    I don't make any claim this is a rational opinion. I've just been very surprised how much more I like transparent heat shrink than opaque heat shrink.

    No, I changed my mind. I claim this is a rational opinion. Opaque heat shrink hides the joint and I think it looks barbaric.

    Heat shrink, transparent heat shrink, bah, humbug!

    If you want to do the job properly you lace up your cables:

    Those were the days. I don't know how many miles of lacing I did in my NZ Telecom days. Quite satisfying though getting it all evenly spaced.

    I'm sure most of you have seen the lacing done on Curiosity?

    I don't recall seeing lacing mentioned in the NASA workmanship guide but I think it's safe to assume it's also NASA approved.

    No, do you have any links to such things?

    Make sure and zoom in on the picture Ron links to in post #3.

    I think there's a better picture showing the laced cables. I'll post a link if I find it.

    Edit: This site has some good pictures of Curiosity's knots.

    This adhesive-lined, heat-shrinkable tubing provides sealing and strain relief. The tubing’s internal adhesive coating melts and flows to form the seal.

    Fortunately there were plenty of comments pointing out the similarities between Sleev and heat shrink tubing.

    Apparently they had released a video of the real product but it has since been marked private.

    And they STILL were overfunded by the Kickstarter crowd. Too bad they didn't have more colors to offer, they could have reached several stretch goals!!!

    Wow, absolutely ridiculous KickStarter!!!! $4 for two pieces of glue shrink.... and people fell for it!!!! That is the scary part. Since they don't claim to be making the shrink, my guess is that they are buying a full roll of glue shrink from a reputable source (3M, Raychem, etc) and just cutting it into pieces.

    So, lets see, 3M adhesive lined 1/2" Polyolefin tubing is $242 for 12 pieces that are 48" long. These sleev gimmicks are about 3" long, so (12*48)/3 equals 192 pieces. Sold as a pair, so net is 96 pairs for $242 and ends up $2.50 a pair for QUALITY, PROVEN, BACKED, and SUPPORTED product.
    http://www.shop3m.com/3m-heat-shrink-multiple-wall-polyolefin-tubing-eps400-450-48-black-12-pcs-48-in-length-sticks.html?WT.ac=US_EnterpriseCatalog_EPS400-.450-48%22-Black-12%20Pcs

    The worst thing about the Kickstarter is that their recommended method for shrinking is a lighter. Really!?!?! Have they ever used adhesive lined tubing? Even heating ensures proper flow of the adhesive.

    Yes, but their heat shrink tubing comes packaged in recycled paper.

    Not only is the paper recycled, it's also transparent.
