This assortment is particularly suitable for DIY enthusiasts, craftsmen, field service, service workshops, electronics technicians, and laboratory supplies. You will receive a 120-piece premium heat shrink connector assortment with a shrink ratio of 2:1, suitable for cable cross-sections from 0.25 to 6 mm². The hot melt inner adhesive seals waterproof when properly overlapped – the solder ring connects the two conductors during the shrinking and melting process. The application is very simple: strip the cables and insert them into the connector on both sides until the stripped cable ends overlap or twist under the solder ring. Optimal heating in the melting temperature range until the solder melts is best achieved with a hot air gun, hot air blower, or heat gun. Additionally, premium heat shrink tubing with a shrink ratio of 2:1 in various lengths and diameters from 1.5 to 12 mm is included in an extra assortment box. Delivery includes a transparent assortment box with 120 solder connectors and a transparent assortment box with 800 heat shrink tubes.
