QUADRIOS 1908CA071 Tubo termorretráctil, sin adhesivo, negro, 40 mm, 2:1

Electricians and maintenance technicians rely on this QUADRIOS heat shrink tubing to insulate and protect cable splices, terminations, and bundles in industrial control panels and field installations. The 40 mm pre-shrink diameter slides easily over connectors and irregular shapes, then recovers to 20 mm for a tight, durable seal.
