High Temperature Nylon Corrugated Wire Harness Loom

MJ FLEX WL-PA-N is a non-split nylon corrugated loom for wiring that must endure heat, vibration and repeated mechanical stress. The tough PA wall forms a continuous passage around the harness, helping protect conductors from abrasion, scratches, impact and tension along demanding equipment routes.Compared with general-purpose plastic loom, this nylon construction is selected where fatigue resistance, oil contact and higher service temperature are important. Its flexible ribbed profile follows bends and absorbs movement, making it well suited to automotive harnesses, mobile machinery and electrical assemblies.

    The wear-, scratch- and impact-resistant construction is suitable for cable routes where contact with surrounding parts may cause surface damage. Application suitability depends on the actual operating conditions.

     

    How to Select

    Measure the total outside diameter of the cable bundle and compare it with the available WL-PA-N inside diameters. Select a size that allows the wires to pass through without excessive force while avoiding unnecessary looseness after installation. If connectors or terminals must pass through the tubing, include their maximum dimensions in the assessment.Confirm the operating temperature, expected abrasion, impact exposure, vibration and routing space. Where oil, solvents or outdoor exposure are involved, verify material compatibility under the actual service conditions.
