sealing and repair sleeves

High temperature sealing sleeves

TE's Raychem sealing and repair sleeves help extend service life and add protection against moisture, corrosion and mechanical abuse of cables and assembles that are subjected to rugged use especially in high temperature applications.

Repair instead of replacing circuits. TE's Raychem sealing and repair sleeves provide water-proofing and mechanical protection against wear and chafing by adding a tough layer of heat-shrinkable tubing in assemblies and cables where rugged use is expected. With multiple high temperatures ranges and sizes, these sleeves can be used over damaged areas to help extend service life, by helping to eliminate the need for immediate replacement of expensive circuits. 

RayOLOn Sleeves

Roll-On Sealing Sleeves

RayOLOn sleeves help protect components such as connectors and splices from salt spray and moisture. They easily roll over the components. If reentry is needed, they can be rolled back and then back into position.
Without the need for heat, installation is fast and easy anywhere and reusability helps eliminate the need for replacement spares.
