TE Connectivity's New Rayseal Repair Sleeve Delivers Fast, Reliable, Large-Gauge Cable Repair

TE Connectivity

HARRISBURG, Pa. – TE Connectivity (TE), a world leader in connectivity, announces its Raychem Rayseal large gauge wire repair (LGWR) sleeve for military aerospace and defense, commercial air, and military ground system applications.

The Rayseal LGWR sleeve is a high-performance, side-entry heat-shrinkable sleeve with an adhesive lining. The product is designed for fast, reliable and sealed repairs to large gauge cables (from 8 AWG up to 4/0 AWG) and power feeders with chafed or cracked insulation. Its side-entry design enables it to be installed without de-pinning connectors or breaking system integrity, significantly reducing repair time and saving money.

“It is costly to disconnect a large gauge cable on an aircraft in order to repair a jacket. Our solution is to provide a side-entry jacket repair method that can be installed over the damaged cable jacket to fully seal it and provide a permanent, robust repair,” said Mark Taylor, Product Manager, Global Aerospace, Defense & Marine, TE.

The Rayseal sleeve’s tough outer fluoropolymer material has been designed to give significant resistance to mechanical abrasion and common aerospace fuels and fluids, as well as for excellent performance at high temperatures.

A high-temperature adhesive lining seals around the underlying damage to the cable jacket in order to maintain the cable jacket properties as close as possible to its original specification. The operating temperature range is from minus 65 degrees Celsius up to 260 degrees Celsius.

The Rayseal LGWR sleeve will be supplied in kit form with abrasive paper for cable jacket preparation, jacket cleaning wipes and high-temperature film tape to allow for effective installation.
