Cellpack SB 2:1 heat shrink tubing is designed to offer reliable protection against chemicals, abrasion and mechanical damage. Thanks to its 2:1 shrink ratio, it fits snugly over the wiring, sealing and protecting every connection.
The handy and compact dispenser makes it easy to unwind the conduit, preventing tangling and splitting. Notched return system prevents the conduit from recoiling, improving efficiency during installation, even in tight spaces or working at heights.
Made of cross-linked polyolefin, this conduit complies with international standards. It is free of harmful substances such as lead and cadmium and offers resistance to fungus, corrosion, high and low temperatures (-55 to +135 degrees).
