UL Listed Silicone Filled B-Connectors 1000-Pack offer a professional-grade solution for secure wire splicing. Installation is straightforward—just insert the wires and crimp using lineman’s or needlenose pliers. The silicone gel filling acts as a moisture barrier, preventing corrosion and ensuring long-lasting connections without the need to strip insulation, thanks to internal teeth that pierce wire coatings. Designed for communication circuits, these connectors are ideal for telecom, CCTV, alarms, and low-voltage systems. Their funnel-entry design simplifies wire insertion, while the durable brass and plastic construction meets UL standards and withstands temperatures from -60°F to 475°F.
