Halogen-Free Shielded Flexible Conduits, Types HFSLA, HFEMS and HFEMCS, are ideally suited  for applications requiring both shielding protection and halogen-free properties. These applications include:

• Aerospace
• Cell Towers
• Data Centers
• Defense
• Healthcare
• Renewable Energy
• Ship Building
• Telecommunications

These conduits provide exceptional shielding effectiveness from electromagnetic and radio frequency interference (EMI/RFI), both ingress and egress. The halogen-free jacketing provides a low-smoke, low-flame spread, zero-halogen product making it ideal for field installation in confined. This jacketing material virtually eliminates the release of acidic gases found in PVC products. These products accept industry standard liquidtight connectors and address the problems of assembly and grounding. 

• Good Shielding: Type HFSLA is a flexible steel conduit with a galvanized steel core, over which a tinned copper shielding braid is applied. The outer jacket is flexible PVC with a temperature rating of -30° to 80° C while the braid offers a minimum of 90% shielding coverage.
• Better Shielding: Type HFEMS offers a better shielding effectiveness than Type HFSLA with a temperature rating of -55° C to 105° C. HFEMS features a flexible core constructed of a helically wound, fully interlocked strip of bronze. An all-temperature PVC jacket is extruded over the core, resulting in a sealed, waterproof raceway when assembled with liquidtight fittings.
• BEST Shielding: Type HFEMCS is a hybrid of HFSLA and HFEMS because it utilizes the same bronze core and PVC jacket as EMS but gets further screening protection from a tinned copper braid as found in the HFSLA product. Type HFEMCS offers the same working temperatures as HFEMS.

These conduits are available in sizes 3/8 - 2" or 4".
