Our 4:1 heat shrink tubing is also available with a "dual-wall" construction. When exposed to heat (usually a bit lower than the activation temperature of the heat shrink), the inner layer begins to flow (just like a hot melt glue). When the tubing shrinks and cools down, the inner layer forms an adhesion layer between the tubing and the component or wire. This provides a watertight seal, protecting the connector and/or wire.
Features:
- 4:1 Shrink Ratio with melt adhesive inner lining (shrinks to 1/4 its original diameter)
- Longitudinal Shrinkage: up to 15%
- Meets requirements of AMS-DTL-23053/4 (formerly MIL-I-23053/4), Class 3
- UL 224 VW-1 and CSA OFT recognized
- Maximum Continuous use temperature 110°C
- Shrink Temperature of 100°C and operating temperature of -55°C to + 110°C
- Crosses to: Sumitomo W3B2(4X), Raychem ATUM 4X, LG GSHS-4635WT
- Typical applications include: Insulation, Wire Identification, Wire Bundling, Mechanical Protection, Color Coding, Lightweight Harnessing, Physical/Electrical Protection of Components, Strain Relief, and Solder Insulation.
