【PREMIUM QUALITY】: Thick copper barrel ensures strong secure crimping every time, providing minimal voltage drop, high current flow, and less heat. These will prevent short circuits and problematic wiring that inferior connectors are known for

【DURABILITY】: Each butt, ring and fork terminal features a thick tinned copper barrel that resists corrosion to hold the wire tight when crimped. The barrel is created from one piece of copper that eliminates the problem of the barrel opening. Your wire will never slip out of the connector

【WATERPROOF】: Insulation tubing has unique dual-walled design. High quality 3:1 shrinkage tubing has a heat-activated sealant lining to provide a 360-degree secure seal. It's flame-retardant, waterproof, and can be used underground

♥ PREMIUM SOLDER SEAL RING: Tubing reduces in size, the enough solder will melt and flow through the stripped wires, ensure a long lasting connection for your application.

♥ BETTER WATERPROOF SOLUTIONS: Double wall design, Hot Melt Adhesive inside ensures wires strongly connected and prevent wires slipping from the terminal; Polyolefin outside tubing provides insulation and improves pullout strength.

♥ ABRASION RESISTANCE HEAT SHRINKABLE TUBE: Premium tube materials are specially designed to be used in harsh environments. Protect the wires and cables from abrasion, cutting, scuffing and low impact situations.
