3 Branches Heat shrink Boots


Product Overview:

KEYUACE heat-shrinkable cable breakouts and transitions offer strain relief protection for cable assemblies used in harsh environments. These products help prevent penetrating exposure from salt water, fuels, and petroleum-based solvents. Breakouts and transitions are available in popular “T” or “Y” shapes or with several openings for multi-branched cables, and with a variety of exit angles and branches to offer strain relief, sealing and mechanical protection for multi-branched cable harness assemblies. Suitable materials can be selected according to the different requirements of the use environment to meet the multi-level requirements of military and commercial use. It is simple to install and use, and is waterproof with glue.
