RACO

RACO liquid-tight connectors are available with an insulated throat or a non-insulated design. Insulated models have a plastic liner at the conduit entry to protect conductor insulation from abrasion at the fitting throat. Non-insulated models are used where the installation does not require that protection or where a separate insulating bushing is specified. Both types are made of steel or malleable iron and have NPT threads for terminating flexible metallic liquidtight conduit. Some RACO liquid-tight connectors also include an external bonding jumper to maintain grounding continuity across the fitting. Selection depends on the raceway specification, conductor type, and the applicable electrical code requirements for the installation.

RACO liquid-tight conduit fittings are cataloged in trade sizes from 3/8 in through 4 in, with some families extending to larger sizes. The sample catalog includes 2-1/2 in and 3-1/2 in straight connectors and a 2-1/2 in 90-degree connector. Threads are NPT, with examples such as 2-1/2-8 and 3-1/2-8. Configurations include straight, 45-degree, and 90-degree bodies, in insulated and non-insulated versions. Material options include steel and malleable iron. Buyers should confirm the trade size and thread form against the conduit and enclosure being connected, since liquid-tight fittings are sized to specific conduit trade sizes and are not interchangeable across sizes.

RACO flex-to-EMT couplings, such as the 1482 and 1483, join flexible conduit to electrical metallic tubing. They are zinc screw-in/compression fittings: the flexible conduit end is secured by the screw-in feature, and the EMT end connects by compression. This provides a mechanical transition between two raceway types without additional adapters. They are used where a run changes from flexible conduit to EMT, for example at equipment connections or where vibration isolation is needed at the end of a rigid raceway. Trade sizes include 1/2 in and 3/4 in in the sample catalog. Installers should verify that the flexible conduit type and EMT size match the coupling's listed compatibility before installation.

RACO short elbows are 90-degree iron fittings used to change direction in rigid metal conduit and intermediate metal conduit runs. They have NPT male-to-female threads and are listed to UL 514B. The sample catalog includes 1/2 in and 3/4 in trade sizes with overall lengths of approximately 2-1/16 in and 2-3/32 in respectively. They are installed where a raceway must turn a corner, such as at wall penetrations, along structural members, or at equipment entries. Because they are threaded, they require the conduit to be threaded to match. They are part of the RACO conduit fitting family and are selected by trade size and thread type to match the raceway.

Many RACO conduit fittings carry UL listings or CSA certification, and the specific standard depends on the product family. For example, RACO short elbows are listed to UL 514B, and certain liquid-tight connectors are CSA Certified. The product data for each item should be checked for the applicable listing or certification before specifying or installing. 3G Electric's catalog entries include standards information where available. Because listings can vary by model and revision, buyers should confirm the current certification for the exact manufacturer part number being ordered, especially for projects requiring third-party inspection or code compliance documentation.

RACO flexible conduit couplings in the sample catalog are made of zinc. This includes the 2272 flex screw-in coupling for 1/2 in trade size flexible conduit and the 1482 and 1483 flex-to-EMT couplings for 1/2 in and 3/4 in trade sizes. Zinc is used for these fittings because it can be die-cast into the required threaded and compression geometries and provides corrosion resistance in typical indoor and protected outdoor locations. For more severe environments, buyers should review the specific fitting's material and finish data. The couplings are designed to join sections of flexible conduit or transition flexible conduit to EMT, and they are selected by trade size and conduit type.
