Battery Cable Heavy Wall Heat Shrink Tubing - 1" x 3" - Black/Red (2-Pieces Combo Pack)BHW is coated internally with a dual-purpose thermoplastic liner which flows and encapsulates when heated. When cooled, the tubing offers the mechanical strength of a superior adhesive and the corrosion protection of a high-quality mastic. Insulation varies with different types of wires, different diameters or tubing may be required. When choosing a size, consider any components or connectors that may need to be covered.Features: Highly abrasion and impact-resistant Easy installation, shrinks when heated over 120 AdegC The thermoplastic liner will adhere to PVC, neoprene and polyolefin, EPR, steel, and aluminum A sturdy, heavy wall tubing with excellent insulating, abrasion-resisting, and strain-relieving properties. The thermoplastic adhesive provides superior environmental protection. Any connection in harsh conditions Adhesive lining provides a barrier against contaminants Excellent resistance to acids and alkalis Good resistance to fuel, oil, and solvents Applications: Splice sealing Primary insulation Cable/jacket repair Direct burial/submersible Strain relief Specifications: Expanded Inner Diameter: 1.1" Recovered Inner Diameter: 0.367" Application Range AWG: 1/0 - 4/0 (.40 - .95) Recovered Wall Thickness: 0.12" Compliances:MIL-I-23053/15 Class 2 Brochure (pdf)
