Product Description

FyreJacket® 1670 is an expandable braided fiberglass sleeve coated with a specially compounded silicone rubber. The product is intended to protect hoses, hose assemblies, tubing, piping, wires, wire assemblies, and cables from heat and abrasion while providing high voltage circuit protection. The thickness of the silicone coating determines the dielectric strength, which ranges from 4 to 10 kV.

Its optimized construction features a highly expandable and flexible characteristic which carries easy installation and superior fit on complex busbar geometries. The high flexibility of FyreJacket® 1670 allows for a relative expansion ratio of approximately 50%.In addition, the sleeve’s inherent thermal insulation and containment properties can be utilized depending on the application. The smooth, high gloss silicone creates a fluid tight barrier, provides additional protection, and is available in a variety of colors for identification purposes.

As shown in these examples, FyreJacket® 1670 maintains a smooth, continuous protective barrier even through tight bends and challenging routing paths. Its flexible construction helps preserve electrical insulation, thermal protection, and a clean finished appearance throughout the installation.
Typical Applications

• Electrical isolation
• Thermal insulation
