OEX ACX1111 Fire Retardant Split Convoluted Tubing 16.3mm Internal Diameter Black 50m Roll Largest Size in the OEX Range The OEX ACX1111 is a split convoluted tubing sleeve in 16.3mm internal diameter, supplied in a 50m 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 16.3mm ID and 20.9mm OD with a maximum bundle size of 16.6mm, this is the largest internal diameter in the OEX split convoluted tubing range. Suited to automotive, marine and caravan wiring environments. Covered by a one year warranty. Product overview The ACX1111 combines the largest internal diameter in the OEX convoluted tubing range with a fire retardant polypropylene material specification, providing both maximum cable bundle capacity and the added safety margin of fire retardant construction. It suits heavy main wiring harnesses, large multi-cable bundles and thick individual cables that exceed the capacity of the smaller sizes, in installations where fire retardant material is preferred over standard corrugated polypropylene. The fire retardant polypropylene material resists ignition and self-extinguishes if a flame source is removed. 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 50m roll is a practical mid-volume trade format suited to workshops needing more coverage than a 10m single-vehicle length without the bulk of a higher-volume roll. 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. 16.3mm internal diameter — largest in the OEX convoluted tubing range: Accommodates large cable bundles and heavy harnesses up to 16.6mm maximum bundle diameter, suited to main vehicle wiring harnesses and thick 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. 50m roll: Practical mid-volume trade format for workshops requiring more than a single-vehicle run without committing to a high-volume roll. One year warranty: Covered by a one year OEX warranty.

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 ACX1111 compare to the ACX1109? Both are 16.3mm split convoluted tubing with the same internal diameter and outside diameter. The ACX1109 is made from corrugated polypropylene with a UL HB or V2 flammability rating and is supplied in a 10m length for single-vehicle jobs. The ACX1111 is made from fire retardant polypropylene and is supplied on a 50m roll for trade and multi-vehicle use. Select based on material preference and quantity required. What is the continuous operating temperature of the ACX1111? The continuous operating temperature is not confirmed in the current product data for the ACX1111. 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.
