An encapsulated splice chuck may include a splice chuck body and a body encapsulation positioned about an exterior surface of the splice chuck body. The encapsulated splice chuck may also include a first forcing cone threadedly coupled to the splice chuck body, the first forcing cone including a tapered inner surface. In addition, the encapsulated splice chuck may include a first forcing cone encapsulation positioned about an exterior surface of the first forcing cone and a first set of wedges positioned within the first forcing cone. The encapsulated splice chuck may include a second forcing cone mechanically coupled to the splice chuck body, the second forcing cone including a tapered inner surface, and a second forcing cone encapsulation positioned about an exterior surface of the second forcing cone. The encapsulated splice chuck may also include a second set of wedges positioned within the second forcing cone.
