HIGH QUALITY-Shrinking ratio: 3:1.Translucent heat shrink tubing provides high tensile strength and resistance to stretch and mechanical damage. Thick barrel ensures strong crimp every time. Your wire will never slip out of these heat shrink butt connectors.
DURABILITY-Dual-walled design, polyolefin tubing in outside and hot melt adhesive in inside. The thicker and better copper of the heat shrink butt connectors provides increased current flow andensures less voltage drop, preventing wiring failures and reducing equipment downtime.
