RT-375 Very clear, thin-wall, flexible, fluoropolymer heat-shrinkable tubing RT-375 is a highly flame-resistant, heat-shrinkable, thin-wall tubing that has excellent clarity. It is manufactured from a modified fluoropolymer whose properties include toughness, chemical resistance, and high-temperature performance. A very thin wall gives RT-375 excellent flexibility. Applications include protection of wire and cable markers subject to abuse; bundling and jacketing of wires and cables to protect them from mechanical and chemical abuse while permitting full inspectability of the item covered; and protection of electronic components without losing the ability to identify the part. RT-375 is UL-recognized and CSA-certified at 150C, 600 V, with a VW-1 flame-retardancy rating. Temperature rating Full recovery temperature: 150C Continuous operating temperature: -55C to 150C Recommended maximum temperature for use as a primary insulator: 135C Specifications* (R) Type RT-375 Raychem RT-375 Military AMS-DTL-23053/18, Class 2 UL E85381 VW-1 CSA LR31929 VW-1 *When ordering, always specify latest issue.
