When economy is the driving force, H2N0.19BK48-200 Shrinkflex 2:1 heatshrink tubing is the answer. Not as versatile as a high shrink ratio product, 2:1 will still slide easily over small plugs and connectors and provide a tight seal in many applications.
Shrinkflex heatshrink tubing is the ideal way to create a tight, professional finish on any wire, hose, or cable management project.
