Shrink Sleeve W/Numbers

The Taylor/Vertex Shrink Sleeve with Numbers is a numbered 1-8 spark plug wire identification system designed to organize and label ignition leads in multi-cylinder engines. This set of 16 black shrink sleeves provides clear, durable labeling for spark plug wire routing and diagnosis, ensuring technicians and engine builders can quickly identify each lead during assembly, service, or troubleshooting. The numbered design eliminates confusion during complex ignition system work.

Each shrink sleeve features permanent numbering that remains legible through heat cycling and repeated use. The black polyolefin construction provides excellent insulation and protection for spark plug wires, resisting abrasion and minor impacts in engine bay environments. At 2.9 inches in length and 0.75 inches in diameter, these sleeves fit standard spark plug wire diameters without restricting cable flex or routing. The set includes multiple numbered sleeves, supporting 8-cylinder configurations and providing extras for backup or replacement application.

This product is essential for automotive technicians, engine builders, and restoration specialists working on V-8 engines, hot rods, classic cars, and performance builds. Clear spark plug wire identification reduces installation errors, simplifies future maintenance, and speeds up diagnostics when ignition issues arise. The numbered system is particularly valuable for complex custom builds where original documentation may be unavailable or non-standard wire configurations are used.

Taylor Corporation, operating under the Vertex brand division, manufactures electrical identification and protection products for industrial, automotive, and professional markets. The Taylor/Vertex shrink sleeve line is recognized for consistent quality and practical engineering that supports field and shop use across diverse engine platforms and ignition configurations.
