Essential Info

If you're looking for a dependable, economical way to create a tight, professional finish on any wire, hose or cable management project, look no further. The perfect solution for any termination application, Shrinkflex heatshrink tubing easily installs over connectors and splices. Once shrunk will hold tight even in elevated temperatures.

Though not as versatile as a high-ratio shrink product, 2:1 will still slide easily over small inline splices and connectors and provide a tight seal in many applications. This tube shrinks from 1/2 inch (12.7) to 1/4 inch (6.4mm) when exposed to 194° heat.
