Weatherproof wire connectors designed specifically for above-grade, interior, or exterior connections exposed to damp, wet, or corrosive environments. They are the perfect twist-on solution for connections that require protection from the elements. The swept-wing design makes the connector easy and comfortable to apply, while the pre-filled, silicone-based sealant protects against moisture and corrosion, eliminating the need for heat-shrink or excessive taping. Feature tough, flame-retardant shells that withstand most rugged environmental extremes and are listed to UL 486D for use in damp or wet locations that are above ground. Due to the pre-filled silicone sealant, these connectors are designed as 1-use only connections. 2 sizes, range 22 to 14 AWG and 18 to 8 AWG.
