Quick Overview

FIT®-321 has a thicker wall for increased durability and a water-resistant inner permanent-bonding adhesive. FIT® heat shrink tubing offers a reliable way to protect and seal terminations or add additional mechanical ruggedness. FIT® preferred heat shrink products are made from premium compounds under the tightest manufacturing controls. This means FIT® will consistently have excellent physical characteristics such as low longitudinal shrinkage and wide temperature ranges while providing an elegant appearance when used alone or on OEM equipment.
