Polypropylene Flexible Non-Split Corrugated Wire Tubing

• Higher Temperature Capability

The polypropylene construction offers thermal resistance for cable routing in environments with elevated operating temperatures, providing a protective outer covering for wire harnesses.

• Reliable Mechanical Protection

The corrugated wall helps protect cables from external friction, scratches and everyday impacts, reducing the risk of mechanical damage during equipment operation.

• Chemical Exposure Resistance

Polypropylene offers resistance to acids, alkalis and certain chemical solvents, supporting cable protection in industrial environments where such exposure may occur.

• Lightweight Cable Management

The lightweight tubing organizes multiple wires into a single bundle while adding minimal weight to the cable assembly.

• Flexible Installation and Routing

The flexible corrugated profile accommodates practical bends and routing paths, supporting convenient cable insertion and installation.

• Polypropylene Construction

Manufactured from polypropylene (PP), offering a lightweight structure, chemical resistance and dimensional stability.

• Flexible Corrugated Profile

The corrugated profile provides flexibility for installation along different cable routing paths.

• Abrasion and Impact Resistance

The polypropylene corrugated wall helps absorb minor impacts and reduce contact abrasion on enclosed cables.

• Electrical Insulation Properties

Polypropylene has electrical insulation properties and provides additional external cable coverage, but does not replace the insulation of individual conductors.

• Resistance to Acids and Alkalis

The material resists certain acids, alkalis and chemical media, with compatibility depending on concentration, temperature and exposure duration.

• Automotive Wiring Harnesses

Protects automotive wiring harnesses against vibration, friction and routine mechanical contact, including suitable engine-compartment routing locations.

• Industrial Machinery Wiring

Protects cables and connecting wires inside industrial machinery from abrasion caused by contact with brackets, housings and other components.

• Electrical Equipment

Organizes and protects internal wiring in electrical equipment, supporting neat cable routing and efficient assembly.

• Industrial Automation Systems

Provides additional mechanical protection for cable bundles in automated production equipment, control units and related assemblies.

• Automotive Electrical Assemblies

Supports cable organization in automotive electrical assemblies where flexibility, thermal resistance and mechanical protection are required.

Measure the total outside diameter of the cable bundle and select a WL-PP-N inside diameter that provides sufficient clearance for wire insertion without excessive looseness. Consider the largest connector or terminal that must pass through the tubing during assembly.Evaluate the operating temperature, routing space, bend radius, vibration, abrasion exposure and possible contact with chemicals. For installations involving acids, alkalis or solvents, confirm material compatibility under the actual concentration, temperature and exposure conditions.As WL-PP-N features a non-split construction, cables must be inserted from an open end. Confirm the installation sequence and tubing length before assembly. For demanding applications, verify the finished cable assembly under representative operating conditions.

• Sizes and Dimensions - Multiple standard inside diameters, outside diameters and wall thicknesses are available. Special dimensions can be reviewed according to project requirements.

• Colors and Identification - Black is the standard color. Alternative colors and product identification requirements can be reviewed according to material availability, production feasibility and order quantity.

• Packaging - Spool packaging, quantity-based packing, product labels and carton markings can be arranged according to order requirements.

• Polypropylene Material Verification - Polypropylene raw materials are checked against approved product specifications and manufacturing requirements.

• Corrugation Profile Control - Corrugation shape, pitch and structural uniformity are inspected to support consistent construction and installation performance.

• Dimensional Inspection - Inside diameter, outside diameter and wall thickness are verified against the specified tolerances for each part number.

• Flexibility and Appearance Inspection - Tubing flexibility and appearance are inspected for cracks, deformation, contamination and other visible defects.

• Final Inspection and Traceability - Part numbers, dimensions, color, quantities, packaging and labels are verified before shipment, with batch records maintained according to order requirements.
