Making assemblies more reliable and durable. TE's Raychem heat shrink accessories are resistant to hydro carbon and extreme temperatures, and can help protect cables from P-clamp and saddle clamp chafing and wear. Heat-shrinkable materials make sizing an easy task and makes installation simple. 

Side Entry Bushing (SEB)

Part Numbers

Pre-coiled side entry reusable silicone bushing designed to be used in high temperature applications where tape or other molded grommets are used.  One strip of this Side Entry Bushing replaces as much as 6 feet and 40 wraps of traditional tapes.  The material is crosslinked and thermoformed to naturally conform to the tight bundle configuration of its application.  The standard Side Entry Bushing has no adhesive layer, so it is easily removed and can be re-used often after repairs have been made.
