Zip-Shield (PFR) Infographic
  • PFR jacketing offers resistance to abrasion and most fluids
  • Pressure track closure system for a secure seal
  • EMI-shielding cloth is lightweight and corrosion resistant

Zip-Shield® (PFR) is an EMI-shielding solution consisting of a wrap-around PFR jacket with a sewn-in EMI-shielding cloth, mesh or foil and a pressure track. The highly flexible PFR-18 material is flame retardant and military grade as well as resistant to abrasion and most fluids. The jacketing is also non-PVC, which makes it a good choice for many nuclear, aerospace and military applications where PVC materials are not permitted. 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® (PFR) is typically paired with Z-Track. The pressure track system will be easy to seal and offer a long-lasting closure, and if re-entry is required, you can easily break out components. The Z-Track is a versatile, medium-duty pressure track closure with an arrowhead-and-channel interlock system. The Z-Track can be sealed with our ZTZ-SP plier tool.

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:

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.
