The waterproof DuraSeal-devices serve the purpose of realising robust and very reliable cable connections. DuraSeal-DF can be easily installed by using a crimping tool (e.g. AD-1522-1). After crimping, the tubing is heated and the inner adhesive melts and flows under pressure from the tubing, filling voids and sealing the splice. The fork terminals DF are colour-coded and available for sizes of up to 6 mm².
