A raintight compression connector has a connector body with first and second portions and a bore extending therethrough. The first portion is dimensioned for receipt of an EMT or RMC conduit. A gland nut threads onto the first portion and a split compression ring contacts the gland nut so as to secure the connector body to the conduit. An upper sealing ring makes sealing contact with the conduit; and a wedge-shaped sealing ring is positioned in the bore of first portion against a shoulder formed in the first portion. The sealing ring contacts a terminating face of the conduit so as to pliably deform around the face so as to form a watertight seal. The second portion is securable to an enclosure. A coupler with two portions similar to the first portion of the connector has corresponding components to form a watertight seal with two conduits.
