Enter cable specs, then click Calculate & Draw.

Disclaimer: The bundle diameter and visual representation generated by this calculator are approximate and intended for planning and reference purposes only. The displayed cable arrangement is illustrative and does not represent an actual packing configuration. Actual bundle dimensions may vary based on cable construction, material properties, packing efficiency, and installation methods. Users should verify all dimensions and product selections prior to final design or implementation.

Overview

Halogen-free, flame-retardant polyurethane jacketing
TPU with fabric reinforcement provides excellent tear and abrasion resistance
Molded-tooth zipper closure allows quick installation and easy re-entry

Zip-Wrap (NHU) is a durable, re-enterable protective sleeve made from halogen-free, nylon-reinforced polyurethane fabric with a molded-tooth zipper closure. The wrap-around design allows cables, wires, and hoses to be bundled and protected without disconnecting components, while the zipper provides quick installation and convenient access for maintenance or modifications.

The NHU-22 jacketing combines the excellent abrasion and chemical resistance of polyurethane with a strong nylon fabric reinforcement for added tear resistance and durability. This flexible, rugged construction helps protect cable bundles from wear and damage in demanding environments, while its halogen-free, flame-retardant formulation makes it an excellent choice for applications with specific material or fire safety requirements.

Available in a variety of diameters and custom lengths, Zip-Wrap (NHU) provides a versatile solution for organizing and protecting cables, hoses, and wire harnesses. Its durable materials and reusable zipper closure make it well suited for installations requiring long-lasting protection, flexibility, and repeated access to enclosed components.

FREQUENTLY ASKED QUESTIONS

Q: What lengths of zippered jacketing are available?

A: Our zipper closed sleeves can be ordered in lengths as short as a few inches to lengths of 100 feet or more. When quoting or ordering, make sure to clearly state the length of each sleeve in inches, which is typically referenced at the end of the part number (-X120.0 for example).

Q: What diameter of jacketing do I need? Is it recommended to oversize?

A: We will often suggest oversizing the sleeve diameter by 1/8” to allow for ease of installation. If the application requires significant bending or flexing we will suggest even more extra room. For assistance with sizing you can also contact one of our design engineers.

Q: Can I cut the Jacketing?

A: Yes*. *Although you can cut the jacketing, we recommend ordering zipper-closed jackets to the exact length required. If you need to trim down your jacketing, make sure you do it from the end opposite the zipper pin/box end and reinstall top zipper stops at the point where you trimmed the jacketing. For more details on cutting or size recommendations please contact one of our design engineers.

Q: Will the zipper keep out water and is it water-tight?

A: No. Our standard zippers do a great job at keeping big debris and dirt out of the jacketing but are not water tight. Our tooth and coil zippers are rated at IP4X, which means they will keep out most dirt and dust but water splashing can enter the jacket. If you need more protection, you may consider a track closure or adhesive closure option.

Q: What is the minimum bend radius of the tubing?

A: There is no minimum bend radius for our Zip-Wrap products. The flexible jacketing material allows for extreme amounts of bending and flexing. The bend radius of the installed tubing is typically dictated by the harness it is covering.
