Overview

General purpose or heavy duty DVH jacketing options
Pressure track closure system for a secure seal
EMI-shielding cloth is lightweight and corrosion resistant

Zip-Shield® (DVH) is an EMI-shielding solution consisting of a protective jacket made from woven, PVC-coated polyester fabric with a sewn-in shielding cloth, mesh or foil and a pressure track. Jacketing choices include either a general purpose 20-mil thick fabric (DVH-20) or a heavy duty 40-mil thick fabric (DVH-40). Both options are military grade and provide abrasion protection — ideal for outdoor use or harsh environments. The 3250 EMI-shielding cloth offers protection from EMI, RFI, and EMF, so you can be confident that your components will not be compromised by these damaging interferences.

Zip-Shield® (DVH) is typically paired with the R-Track or the Z-Track. Either pressure track system will be easy to seal and offer a long-lasting closure. If re-entry is required, you can easily break out components. The R-Track is a light duty pressure track closure and is similar to a zip-lock closure. The R-Track can be sealed manually with a thumb or with an SLR slider tool. The Z-Track is a medium duty pressure track closure with an arrowhead and channel interlock system, and it is the most versatile pressure track option. The Z-Track can be sealed with our ZTZ-SP plier tool. Zippertubing® can also manufacture Zip-Shield® (DVH) with our other pressure track closures upon request.

Jacketing options for Zip-Shield® (DVH) include:

DVH-20: Durable polyester fabric with a PVC coating that is flame retardant, abrasion resistant, and ideal for applications in which components may be exposed to harsh outdoor conditions.

DVH-40: Heavy duty polyester fabric that has a PVC coating and is extremely tough for rugged conditions, such as industrial applications in which abrasion and tear resistance are required.

Features

Engineered for diameters ranging from 0.375” to 4”, with custom sizes available upon request
Provides 360-degree protection of components with inner overlap of EMI-shielding cloth
Pressure track is heat sealed to jacketing for a strong bond

Benefits

Secure pressure track seal with ability to re-enter as needed
EMI shielding for protection against EMI, RFI, and EMF
Jacketing options to fit a wide range of applications or conditions

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.
