OEX ACX1113 Convoluted Split Tubing ID:21.1mm OD:25.2mm - Length 30m

OEX ACX1113 Fire Retardant Split Convoluted Tubing 21.1mm Internal Diameter Black 30m Roll Largest Size in the OEX Range

The OEX ACX1113 is a split convoluted tubing sleeve in 21.1mm internal diameter, supplied in a 30m 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 21.1mm ID and 25.2mm OD with a maximum bundle size of 21.2mm, this is the largest internal diameter in the OEX split convoluted tubing range, suited to heavy multi-cable harnesses and substantial cable runs. Covered by a one year warranty.

Product overview

The ACX1113 is the largest size in the OEX split convoluted tubing range, stepping up from the 16.3mm (ACX1109, ACX1111, ACX1111/100) to accommodate heavy multi-cable harnesses and large cable groupings that exceed the 16.6mm maximum bundle capacity of the 16.3mm 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 without disconnecting connectors. The 30m roll suits workshop jobs and single-vehicle installations where this large diameter is required. 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.

21.1mm internal diameter largest in the OEX convoluted tubing range: Accommodates heavy multi-cable harnesses up to 21.2mm maximum bundle diameter, the largest capacity available in the OEX range.

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.

30m roll: Workshop-friendly length for single-vehicle and multi-circuit jobs at this large diameter.

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 ACX1113 compare to the 16.3mm options? The ACX1113 at 21.1mm ID and 21.2mm maximum bundle is the largest size in the OEX range, suited to heavy multi-cable harnesses that exceed the 16.6mm maximum bundle capacity of the 16.3mm range (ACX1109, ACX1111, ACX1111/100). Select the 16.3mm range where the bundle fits, and step up to the ACX1113 only where the larger diameter is genuinely required.

What is the continuous operating temperature of the ACX1113? The continuous operating temperature is not confirmed in the current product data for the ACX1113. 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.
