20PCS 2 AWG-3/8 Marine Grade Wire Lugs, Tinned Copper Ring Terminal Connectors Ends W/3:1 Dual Wall Adhesive Heat Shrink Tubing, Heavy Duty Anti-Rust Battery Cable Ends

Specification: Contains 20 pieces of 2 AWG 3/8" tinned copper wire connectors, along with 20 pieces of 3:1 dual wall adhesive heat shrink tubing (10 red, 10 black).
Note: The tinned copper surface is prone to scratching. This is normal during the manufacturing and assembly process and will not affect the lug's electrical performance.
Marine Grade: Battery cable lugs are made from pure copper, thick and sturdy; with a tin-plated surface treatment that has passed 48 hours of salt spray testing, they are rust-resistant and corrosion-resistant, ideal for automotive and marine use. Dual Wall Adhesive 3:1
Heat Shrink: When heat is applied, the inner adhesive lining melts and shrinks tightly around the wire, providing excellent insulation and protection against moisture and corrosion; the outer wall resists wear and tear for lasting durability.
Practical Design: Durable 2 AWG copper lug features a thick wall for superior conductivity and impact resistance; the closed-end pad design shields cables from moisture for safe, reliable connections, and a flared opening allows for easy wire insertion.
Wide Applications: Tubular ring terminals meet US standard copper eyelet terminal specifications, are compatible with solid or stranded wires, and support soldering or crimping. They are commonly used in applications such as automobiles, RVs, yachts, caravans, solar panel systems, and marine power systems.
Easy to Use: Insert the cable into the lug, crimp it firmly, and then seal the connection with the included heat shrink tubing. Please verify that the size of the M8 battery cable lug and the 15.4 mm heat shrink wrap meets your requirements before purchasing
