Electrical conduit coupling devices are disclosed that include a casing formed of a steel tubing that, in turn, includes a rear portion and a front portion, an elastomeric "O" ring secured at the front portion by a retainer and an end cap. The electrical conduit coupling devices further include a clamp that is arcuate in shape, and in one embodiment, has ends separated from each other to form a gap therebetween which is diametrically located opposite a cut-out in the central region of the clamp. The cut-out cooperates with the separated ends to allow the clamp to clamp around a conduit that is inserted into the electrical conduit coupling device. The electrical conduit coupling devices provide for not only rigid connection to a conduit, but also a waterseal or concrete seal connection therebetween. |
