Drainable enclosure for explosion-proof electrical systems

摘要

A hazardous location sealing fitting is provided with a multipart assembly so that the fill and drain opening may be maintained in a vertical orientation irrespective of the conduit orientation. The main body member comprises a "T" with a service port through which a fiber dam is placed to limit the volume of the sealing chamber. Subsequently, an auxiliary body member is coupled to the main body member at the service port. The auxiliary body member includes the fill and drain port together with a barrier dam and baffle for limiting the amount of sealing compound placed in the sealing chamber and directing the sealing compound into the sealing chamber, respectively. Because the main and auxiliary body members comprise separate parts, the fill port may be positioned with its axis in a vertical plane irrespective of the orientation of the axis of the conduit coupled to the main body member.
