Appleton Electric EYD-36 Fill, Sealing Fitting, 4 5/16 in 25%, 1 in FNPT x 1 in MNPT Ends, Grayloy Iron

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.
