Overview

VNH jacketing is flexible, flame retardant, and adheres to Mil-C-20696 military specification
The internal EMI-shielding layer is lightweight and flexible
Features a secure pressure track closure system

Zip-Shield® (VNH) is a military-grade EMI-shielding solution, featuring a jacket made from military grade fabric with an integrated shielding layer of cloth, mesh, or foil, and a pressure track closure. The VNH jacketing material complies with Mil-C-20696 standards and offers a flexible, medium-weight nylon fabric that is PVC coated and flame retardant, providing durable protection in rugged environmental conditions. This product features a full 360 degree shielding layer that ensures robust defense against EMI, RFI, and EMF interference, safeguarding your components from potentially damaging signals. Zip-Shield (VNH) is provided with one of our high performance foil shields, flexible metalized fabrics, or a conductive mesh shield depending on the industry and requirements.

Zip-Shield® (VNH) is compatible with Z-Track, R-Track, D-Track, or EZ-Track interlocking systems; all of which offer easy sealing and a reliable closure. For applications where re-entry is needed, components can be accessed and resealed without difficulty. Reference our FAQ section for help choosing the best material and closure combination or reach out to one of our applications engineers for specific recommendations.

FREQUENTLY ASKED QUESTIONS

Q: What is the difference between the track closure styles?

A: Each interlocking track profile has unique benefits and trade-offs. To learn about them you can review our Track Comparison.

Q: How do I close the jacketing?

A: Some tracks can be closed by hand, but we also offer closure tools to assist with installation. For more information on closing the specific tracks you can view our helpful videos or installation guides:

How to install Z-Track
How to install R-Track
How to install D-Track (same instructions for EZ-Track)

Q: Can I cut the tubing?

A: Yes. Standard scissors are suitable for cutting through most Zip-On jackets and tracks.

Q: What lengths of material are available?

A: Typical spool lengths for most sizes are 100 feet, but will depend on total order footage. Custom lengths can be provided, just make sure to ask when ordering or include details on the PO for the lengths required.

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

A: Our different track closures are rated between IP54 and IP55. This means they are not water tight but will provide significant protection against moisture and fluid ingress.
Some users will apply tape or a sealant to the track, after closing, to provide additional protection.

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 install
when using a closure tool. 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: What is the minimum bend radius of the tubing?

A: There is no minimum bend radius for our Zip-On 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.
