Bridgeport Fittings 253-RT2 Raintight Emt Compression Connector

Product Description

The BRIDGEPORT FITTINGS 253-RT2 is a 1-1/4 inch raintight screw-on compression connector designed to join EMT conduit to an electrical box or enclosure with a watertight seal. Constructed from die cast zinc, it delivers a precise fit and strong corrosion resistance in demanding environments. The connector includes an internal sealing ring, a knockout gasket with a rubber insert and steel retaining ring, and NPT threads for a secure box connection. This fitting is UL Listed and rated for NEMA Type 2, 3, 3R, and 4 enclosures. Licensed electricians and electrical contractors install this connector in commercial and residential conduit runs where moisture protection is required.

The 253-RT2 is suited for wet and damp location installations where EMT conduit terminates at a junction box, panel enclosure, or outlet box. The raintight design makes it appropriate for outdoor panels, rooftop equipment connections, and exposed conduit runs subject to rain or washdown. At the 1-1/4 inch trade size, this connector is also listed for use with aluminum EMT, expanding its range of compatible conduit material. It is part of a connector series covering trade sizes 1/2 inch through 4 inches.

Installation Notes

Installation is performed by a licensed electrician in accordance with the National Electrical Code (NEC). De-energize all circuits in the enclosure before beginning work.
