Our 4:1 over-expanded flexible, flame-retardant polyolefin heat shrink tubing is used for special circumstances such as cable jacket retrofitting or repair, and electrical insulation of wire assemblies with oversize components or connectors. The over-expanded product configuration easily fits over the end of a connector, and shrinks down to 1/4 of its original diameter to fit snugly over the wires. Our tubing is available in 4-foot sections and meets requirements of AMS-DTL-23053/5 (formerly MIL-I-23053/5), Class 1 UL 224 VW-1 and CSA OFT recognized.
