• Automotive Wiring Harnesses
Nylon non-split wire loom tubing helps protect automotive wiring harnesses from abrasion, scratches and impact during vehicle operation. Its flexible corrugated structure supports organized cable routing within available installation spaces.
• Engineering Machinery
Designed for cable protection in engineering machinery, WL-PA-N helps reduce mechanical wear caused by contact with equipment structures and surrounding components.
• Electrical Equipment
The tubing organizes and covers internal wiring in electrical equipment, helping maintain neat cable routing while providing additional external mechanical protection.
• Electronic Equipment
WL-PA-N supports wire organization and external protection in electronic equipment assemblies where flexibility, abrasion resistance and compact routing are important.
• Cable Routes Exposed to Mechanical Contact
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.
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.
