This large set is particularly suitable for hobbyists, tradesmen, field service, service workshops, electronics technicians and laboratory equipment. The inner hot melt adhesive ensures a watertight seal when properly overlapped. Ideal for repairing or connecting cables and lines (lawnmower cables, signal cables, etc.), service, production or hobby. The application is very simple: Strip the cable and insert it on both sides until the stripped cable ends overlap. Crimp with crimping pliers and then activate the heat-shrink tube in the appropriate temperature range - preferably with a hot air gun. Waterproof, UL-REACH and RoHS compliant.
