The 250 PCS Solder Seal Heat Shrink Wire Connector Kit offers a comprehensive, versatile & innovative wiring solution. This assorted kit includes an extensive selection of premium solder & seal butt connector sizes. Easy & quick identification, color coded solder seal heat shrink wire butt connector pieces. Heat shrink insulated tubing protects splices from water and corrosion, while providing high tensile strength and resistance to stretch, vibration and mechanical damage.

• EASY IDENTIFICATION & KIT CONTENTS - The assorted Solder Seal Wire Connector kit includes 250 PCS, stored in convenient hard shell case, for easy organization & storage! 10 PCS Yellow 12-10 AWG, 25 PCS White 26-24 AWG, 30 PCS Blue 16-14 AWG, 35 PCS Red 22-18 AWG, and 150 PCS Black Connectors. Color-coded tubing, ensuring you identify & select the right size connector. Measure your wire & select the appropriate solder seal butt connector for your electrical wiring application need.

• EXTENSIVE VARIETY FOR ALL APPLICATIONS - Amazing assortment of Solder Seal Heat Shrink Wire Connectors. Working on your boat, vehicle, engine, power tools, home, laboratory, audio, science project, electron. The Solder Seal Wire connectors with melted solder ensure strong wire connection, increased current flow & insulated water proof connections! No need to crimp! The transparent sleeve connector provides precise operating control & inspection of solder & seal heat shrink wire connection.

• DURABILITY, WATERPROOF & INSULATED - The assorted Solder Seal Heat Shrink Butt Connectors are manufactured from one seamless piece of Insulated tubing, a unique dual-walled design, ensuring a waterproof seal & preventing wire corrosion. Polyolefin tubing on the outside and hot melt adhesive inside (resulting in 2:1 shrinkage ratio), glue sealant lining, flame retardant translucent heat shrink tubing, provides high tensile strength, as well resistance to stretch and mechanical damage.

• SUPERB WIRE CONTACT & EASY USE - The high quality copper barrel provides increased current flow, and ensures less voltage drop, preventing wire failures and reducing tool equipment downtime. The thick barrel allows for a strong seal every time, your wire will not slip out of the connector. Strip wire insulation, insert the respective wire ends to solder & seal connector, apply heat with continuous rotation of connector, solder adhesive will flow, filling all gaps within the terminal.
