PO Non-shrinkable Tubing
Cold Shrink 3–6 Core Silicone Rubber

Cold Shrink Breakout Silicone Rubber Boots for Multi‑Core Cables

Cold shrink silicone rubber breakouts are factory expanded and mounted on removable inner supporting plastic cores. Supplied for field installation in a pre‑stretched condition. After positioning around the breakout area of a 3,4,5,6‑conductor cable, the supporting core is removed, allowing the silicone rubber boot to shrink down to a predetermined diameter – creating an environmental enclosure for individual cable phase legs and the overall cable jacket.
