Weatherproof wire connectors designed specifically for above-grade, interior or exterior connections exposed to damp, wet or corrosive environments. 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, the connectors are designed as a 1-use only connection.
