1/2 Inch flame retardant wire loom tubing made from durable nylon material and coated with a flame retardant material. Sold by the foot. In the event of a serious wire failure such as a short circuit in your wire harness, the coating will snuff out any flames, helping to prevent additional damage due to fire. Excellent for use inside engine compartments and other wire covering needs where flame retardant is a requirement. Meets UL approval and is CSA certified. The wire loom is corrugated, providing greater flexibility and strength. A full length slit makes inserting wires into the loom easier, especially when using a wire loom insertion tool. Black with a blue stripe. When a flame retardant wire covering is required, this is the wire loom of choice. Temperature range of -40° C to 135° C (-40° F to 275° F).
