• The spiral-melted adhesive on the inner layer of the heat shrink cable cap provides excellent flexibility after shrinking. • Offers moisture-proof sealing protection for PVC cables, both outdoor and underground, as well as for power communications and lighting line terminals. • Size: 15 x 45 mm. Outer diameter: 17.5 mm. Shrink ratio: 3:1. Shrink temperature: 80 ℃ ~ 120 ℃. Material: PO. • The package includes 15 heat shrink caps. • Made with temperature-resistant and flame-retardant materials, these caps are safe and reliable, with strong resistance to chemical corrosion, good heat resistance, and excellent insulation. • The inner thermofusible adhesive layer provides airtight protection and facilitates easy installation on cable terminations. • Provides sealing, waterproofing, insulation, and protection effects for electrical and control cable terminals. • Instructions for use: 1. Place a heat shrink cable gland over the outer protective layer at the end of the cable. 2. Heat the heat shrink cable gland to shrink it around the end of the cable. 3. Control the heating temperature well and stop heating when the shrinkage is in place and the glue overflows. • There may be slight differences due to manual measurement.
