DESIGN: Our 200 box solder sleeves contain hoses in various colors and sizes, so there is something for every case. The transparent sleeve makes it easier to control the result! FUNCTION: The desired wires are inserted into the hose, pressed firmly with pliers and then heated. Now the adhesive melts and seals the wires waterproof! MATERIAL: Our polyolefin hoses are finished with a seamless copper tube and hot melt adhesive on the inside. Due to the low shrinkage temperature of 80°, the wire is not damaged. QUALITY: The heat shrink connectors are very tear and tensile resistant, waterproof and protect against possible defects caused by environmental influences and external influences. A must-have in every home and workshop! MISCELLANEOUS: The scope of delivery includes ONLY the 200 box of solder connections! No matter what you want to use the solder connectors for, they are suitable for work in the workshop, for DIY projects or even for simple household tasks. The adhesive flows into all gaps during melting, creating a 100% sealed, waterproof insulation! These shrink connectors make it possible to create a stable solder connection - in just a few simple steps within a few seconds! The colour-coded hoses are provided with a wire imprint - this makes it easier for you to identify the crimp hoses used and simplifies the selection of the right shrink connection! - Tear-resistant, tensile-resistant, waterproof - With storage box - Made of PVC (polyethylene) -Transparent - Color-coded - With wire imprint The set contains the following crimp connections: - 90x Red (wire range 0.5- 1.5 sqmm) - 90x Blue (wire range 1.5- 2.5 sqmm) - 20x yellow (wire range 4.0- 6.0 sqmm) Properties: - Working Temperature: -55°- 125° - Shrink temperature: 80° - Melting temperature: 130° - Shrink ratio: 3:1
