3M™ 91-AHA 23N Warm-shrink connection kit with concentric isolation, 4 x 50 - 4 x 70 mm²

3M™ 91-AHA series ensures a moisture sealed connection for low-voltage shielded and armoured cables. Kits are designed for a wide range of cross sections which reduces the number of stock items that needs to be managed. The kits can be used with commonly available crimp connectors. The heat shrink inner tubes have hot melt adhesive inner coating which enables a watertight connection when the adhesive melts during the shrinking process. The outer tube is manufactured of heavy duty, thick wall, flame retardant material.
