Flexible, Premium Grade PVC Flat Cable Jacket, 20 Mil

Z flex® (63) is an economical, heavy duty, pull-thru jacketing system for flat cables made from Zippertubing's type 63-20. This configuration is ideal for inter-connection applications where mechanical protection is required and a sealed, flat, tubular jacket is desirable. Z flex® is supplied in reel form and is easily cut to any length required.

A special "blue-line" nylon cloth leader inside the jacket is provided for fast, easy pull-through of the cable. Z flex® (63-20) is available in many standard sizes to fit the most popular flat cable sizes ranging from 20 to 64 conductors. Custom sizes and colors are also available.
