Polypropylene Flame retardant wire loom is manufactured to meet the stringent requirements of the marine and emergency vehicle industries where extra protection is necessary. FR wire loom meets UL 94-V2 rating for flame retardancy. The high-rise ridge of this Flame retardant loom tubing offers greater flexibility without twisting, tangling, or slit separation. It is distinctly identified by a blue stripe running its entire length. While some protective tubing is rigid, our Flame Retardant Polypropylene Wire Loom fully guards your vital cables and wiring against not only intense heat but also abrasion, chemicals, impact, and crushing, while retaining all the flexibility your cables had before.

Compliant with the European Union's Directive 2015/863 (RoHS 3)
