Product parameters:Material: polyolefin and solder tinPacking list: 100 * Heat Shrink Solder ConnectorsProduct description:Ease of use: The solder connectors are equipped with a transparent sleeve that allows precise control when used with wires inside. This makes wire assembly simpler and more efficient.Strong connection: Thanks to their design, the tubes reduce in size when heated, allowing the solder tin to melt and pass through the grooved threads for a solid hold. This connection ensures reliable electrical conductivity.Strength and insulation: Heat shrink solder connectors are made of polyolefin that shrinks when heated. This improves stretch resistance, provides insulation seal and wire control, ensuring a secure connection. Versatile application: These solder connectors are suitable for a variety of areas such as automotive, trains, aerospace, electric power and electronics, providing a practical solution for many. Reliable Design: Solder connectors are designed with a double wall, with polyolefin tubing on the outside and hot melt adhesive on the inside. This allows for visual inspection, prevents corrosion, and ensures a reliable seal.
