7-1/2" Sealing Fitting, 25% Fill, 2-1/2" FNPT x 2-1/2" MNPT Ends, Aluminum

Explosionproof, dust-ignitionproof, and raintight, this sealing fitting is for use with threaded rigid metal conduit and IMC. It prevents the passage of gases, vapors, or flames from one portion of a conduit system to another. It restricts any explosion to the sealed-off enclosure, and prevents pressure piling within the conduit system. A smooth, rounded integral bushing in each hub protects conductor insulation. The accurately tapped, tapered threads provide tight, rigid joints and ground continuity.
