OEX ACX1108 Convoluted Split Tubing ID:12.6mm OD:15.7mm - Length 75m

OEX ACX1108 Fire Retardant Split Convoluted Tubing 12.6mm Internal Diameter Black 75m Roll

The OEX ACX1108 is a split convoluted tubing sleeve in 12.6mm internal diameter, supplied in a 75m length in black. Manufactured from fire retardant polypropylene with a 120°C melting temperature, the split design allows cables to be inserted from the side without threading. At 12.6mm ID and 15.7mm OD with a maximum bundle size of 12.8mm, it accommodates larger cable bundles than the 9.7mm range, suited to heavier wiring harnesses and multi-cable runs. Suited to automotive, marine and caravan wiring environments. Covered by a one year warranty.

Product overview

The ACX1108 steps up from the 9.7mm range to a 12.6mm internal diameter, suited to heavier wiring harnesses, multi-cable runs and larger-gauge cable groupings that exceed the 9.9mm maximum bundle capacity of the 9.7mm sizes. The fire retardant polypropylene material resists ignition and self-extinguishes if a flame source is removed, providing an added safety margin over standard polypropylene sleeving in automotive wiring environments.

The split design allows cables to be pressed in from the side along the lengthwise opening without threading from one end, making it practical for retrofitting protection to installed harnesses and organising wiring runs without disconnecting connectors. The 75m roll suits trade workshops running regular wiring protection work at this size. Confirm the continuous operating temperature rating with OEX if this is a specific requirement for your underbonnet or high-heat application.

Features and benefits

Split design for retrofit installation: Cables snap in from the side without threading, allowing the tubing to be added to existing wiring runs without disconnecting connectors or rerouting cables.

Fire retardant polypropylene: Resists ignition and self-extinguishes if a flame source is removed, providing an added safety margin over standard polypropylene in automotive wiring environments.

12.6mm internal diameter and 15.7mm outside diameter: Accommodates larger cable bundles than the 9.7mm range, with a maximum bundle size of 12.8mm suited to heavier wiring harnesses and multi-cable runs.

Black: Supplied in black, suited to standard automotive wiring presentation.

Convoluted construction: Flexible and bendable while maintaining cable protection against abrasion and chafing, suited to routing through bends and tight spaces.

120°C melting temperature: Provides resistance to high-temperature environments.

75m roll: Trade format for workshops running regular wiring protection work at the 12.6mm size.

One year warranty: Covered by a one year OEX warranty.

Frequently asked questions

What is split convoluted tubing? Split convoluted tubing is a flexible ribbed sleeving with a lengthwise split along one side. Cables can be pressed into the split opening rather than threaded through from the end, making it easy to add protection to existing wiring without disconnecting anything. The convoluted ribbed construction gives it flexibility and abrasion resistance.

What is fire retardant polypropylene? Polypropylene is a lightweight, chemical-resistant thermoplastic commonly used for convoluted tubing. The fire retardant grade used in this product resists ignition and self-extinguishes if a flame source is removed, providing an added safety margin in automotive wiring environments over standard polypropylene sleeving.

How does the ACX1108 compare to the 9.7mm options in the OEX range? The ACX1108 has a 12.6mm internal diameter and 12.8mm maximum bundle size, suited to heavier wiring harnesses and multi-cable runs that exceed the 9.9mm maximum bundle capacity of the 9.7mm range (ACX1104, ACX1105, ACX1105/250). Select the 9.7mm range for medium-sized bundles and the ACX1108 for larger or heavier cable groupings.

What is the continuous operating temperature of the ACX1108? The continuous operating temperature is not confirmed in the current product data for the ACX1108. The melting temperature is 120°C. Contact us to confirm the continuous operating temperature before purchasing if this is a specific requirement for your application.

How do I cut split convoluted tubing to length? Split convoluted tubing can be cut with scissors, side cutters or a sharp blade. Cut between the ribs rather than through them for a cleaner end.
