ABSTRACT:
A rain tight fitting for connecting electrical metal tubing to a panel. The rain tight fitting includes a tubular body having an inner bore and a rearward end. A threaded outer periphery and a seal ring seat are included on the rearward end. A seal ring is disposed against the seal ring seat and a compression ring against the seal ring. A compression nut is threaded upon the rearward end and tightened thereon to force the seal ring tightly into the seal ring seat and against the outer periphery of the metal tubing. An effective rain tight seal is formed by the close tolerances between the inner periphery of the seal ring and the outer periphery of the metal tubing and by the hardness of the seal ring.
