ZTT® (ALS-5)

Drawing No. ZT17-09-004

 product image

A thin, lightweight, high-temperature, complete 360° thermal-barrier, highly-flexible pull-through sleeve that is intended to protect your cables/wires, electronic sensors, insulation blankets, automotive wires near the engine compartment, and so much more.

The ZTT® (ALS-5) is able to cover many diameter cables and can be customized to fit virtually any length, allowing your installation to maintain its clean, professional appearance.

ZTT® (ALS-5) uses a jacketing material that is made from a light-weight, highly-flexible, woven glass fabric with a flame retardant, reflective aluminum heat barrier coating. The ALS-5 jacketing material can withstand continuous temperatures of up to 350.6°F.

The product is inversely sewn in a tear-drop shape, using a “lock-stitch” with a high-temperature, mil-spec Kevlar thread. This specific Kevlar thread is considered to be one of the most durable threads on the market today, resistant to bacteria, mildew, abrasion, age, and short-term heat burst exposure. During the sewing process, the product is turned inside out so that there are no edges when assembled, which reduces abrasion damage during installation.

Combining both of these high-temperature materials in one product produces a staggering 350.6°F, durable, 360° thermal protection product that is the perfect choice for applications that require high-temperature, pull-through, cable abrasion protection.
