is Nylon braided sleeving?
Expandable braided sleeving is very similar to those
"Chinese Finger Cuffs" that we've all gotten our fingers
stuck in.. When you push the end back, the sleeving expands to
go over wires easily, and then when you let go, the sleeving comes
back to its original diameter (or the diameter of your wire harness
or bundle, whichever is larger).
Nylon 6,6 is a commonly used material for expando
sleeving. Its abrasion resistance in some cases is superior to
Terephthalate) braided sleeving, but in other cases, it's
inferior. Most braided sleeving is referred to as Nylon braided
sleeving; however, 80-90% of the sleeving used worldwide is actually
As a generalization, PET performs better in gritty,
sandpaper type applications, while the abrasion resistance of
Nylon is much better in wet applications, and applications where
the abrading substrate is smooth (for example, rubbing against
a steel rod).
While Nylon monofilaments
do provide better abrasion resistance in some cases, it also costs
40% more than PET,
and is overkill in most applications. Many manufacturers actually
construct their Nylon braids using a "dual monofilament"
construction, which comprises of two different size monofilaments
in the same braid. Some manufacturers even use a mix of PET and
Nylon in their braid for an "all purpose" product. That's
fine for them, but don't you want a product that's best suited
for your needs?
While the braiding process can be controlled to regulate the
expandibility of the final braid, most expandable Nylon braided
sleeving sold today is made in a standard construction that
before further processing, varies very little between manufacturers.
Standard braids can expand up to 2 times* their nominal size,
allowing for easy installation in complex wiring harnesses,
and a high degree of flexibility in the size used.

our braid is different from our competitors'
What most suppliers won't tell you is that all braid
is not created equally. Most of the low cost "manufacturers"
in the USA don't actually make their own braid. They just buy
bulk spools from a braided sleeving manufacturer, and respool
to smaller, more economical spools. We take this process a few
steps further. With the exception of some of our metallized products
(e.g. our Chrome sleeving), all of our braided sleeving is heat
treated. Our Nylon braided sleeving is also "rounded"
during the spooling process..
Rounding a braided sleeve makes it appear more like
a tube than a flat product. Even spooled, the sleeving hold its
round shape, making for easier installation, and a much better
looking harness. Recently, a customer of ours was so happy when
we switched them over to a rounded braid, we decided to switch
our entire stock over. We are sure you will see the difference
too. Ask your current supplier if they will make a rounded braid
for you. We're sure they'll raise your price by at least 15%.
Here is a picture that illustrates the difference.
Both braids are 1/2" nominal. The top one is from our competitor,
and the bottom one (with the little white tracers in it) is ours.
The pen diameter is 3/8". See how the top one shows a crease?

at the top sleeve, you can actually see the table through the
can I get a fray resistant braided sleeve?
At this time, there are no
fray resistant Nylon braided sleeves available on the market.
We offer two simple solutions
to this problem:
1) Since our braid is heatset,
it has some inherent fray resistance. This will allow for easy
installation without much fray. Cover the ends with heat
shrink tubing (our 3:1
dual wall is a great solution since it's sold in 4 foot pieces
instead of spools).
2) Purchase a hot knife from
us for $99. A hot knife is a great way to get a true non-fray
end on your braided sleeving. Just simply turn it on, and run
the sleeve down the blade, and the sleeve is cut very easily.
Just make sure you're in a well ventilated area. For a picture
