The 811134-000, an alias for TE part number 202A111-3-0, is a non-lipped, straight heat-shrinkable boot designed for direct attachment to connectors to provide environmental sealing and mechanical protection. Constructed from TE's -3 material, a ruggedized, flame-retardant, semi-rigid polyolefin, it operates reliably across a temperature range of -55°C to +135°C. This black molded part offers excellent strain relief for cable breakouts and transitions. It is ideal for use in demanding aerospace, defense, and marine applications where robust performance in harsh environments is critical.
