Multi-Size Wire Connectors – Crimp & Shrink Sleeve Kits

Merrill Size Wire Connectors are designed for secure, waterproof electrical splicing in water system installations. Made to fit multiple sizes, each connector kit includes a heavy-duty brass nickel-plated body, set screws, Allen wrenches, and heat shrink tubing with adhesive and sealant for both large and small wire ends. These connectors ensure a tight, waterproof connection from #4 to #14 gauge wire, depending on the model. Ideal for submersible pump motors and underground electrical splices, our wire connectors comply with NEC code and deliver long-lasting durability in harsh environments. Connect wires to the plated body using Allen wrenches. Shrink the small tube first, then overlap the big tubing and shrink to complete.
