The Copperhead SCB-01 is a twist‑on / twist‑lock wire connector designed for direct‑bury utility applications. It is prefilled with a dielectric silicone sealant that remains flexible and protects the splice from moisture and corrosion. The connector joins copper‑clad steel or copper conductors (solid or stranded) and is rated up to 600 V and 105°C (221°F). Typical use is for tracer wire, grounding connections and other underground splice applications; SCB‑01 is commonly supplied in 20‑pack blister/bulk packaging.
