HellermannTyton HFT-A 12,7mm tubo termorretráctil negro 2:1 - 161-42100

Electrical connections exposed to moisture, abrasion, or mechanical stress can fail prematurely. This heat shrink tubing provides a reliable seal that insulates and protects cables, splices, and terminations in demanding environments.

Who is it for

Electricians, panel builders, and maintenance technicians who need durable insulation and strain relief for wire harnesses, cable joints, and connector transitions.
