Impeccable Quality:Made of high-quality hot melt adhesive material which will melt the rich adhesives and wrap the solder wire connectors to form a seal when being heated,the solder seal connectors ensure moisture resistance and strength for durable wire connection in wet conditions.
With its EVA materials,the heat-shrink tube of solder seal wire connectors provide clear visibility of the soldering penetration and premium abrasion resistance for long-term reliability.

Customers say
Customers find these wire connectors easy to use, particularly for radio installations, and appreciate their solid connections that are stronger than traditional crimp style ones. The connectors provide a nice tight waterproof seal, and customers consider them good value for money, noting they save money compared to local purchases. The melt rate and durability receive mixed feedback – while some say the heat shrink holds up nicely, others report it disintegrating, and while some find them reliable, others describe them as flimsy.
