Arlington Industries 831RT Rain Tight EMT Compression Coupling, 3/4"

The Arlington Industries 831RT is a 3/4" EMT Rain Tight Compression Coupling designed to join sections of Electrical Metallic Tubing (EMT) conduit while providing a secure, weatherproof seal at the connection point. The compression-style design clamps evenly around the conduit wall, eliminating the need for set screws and reducing the risk of loose or misaligned joints. Because it is rated rain tight, the 831RT is well suited for outdoor, exposed, and other moisture-prone EMT conduit runs where a standard coupling would not provide adequate protection. It offers electrical contractors a dependable way to extend, repair, or complete 3/4" EMT raceway systems in commercial and industrial applications.

Key Features

  • Trade Size: Sized for 3/4" EMT conduit, providing a precise, code-compliant fit for standard electrical metallic tubing runs.
  • Compression-Style Connection: The 831RT uses a compression fitting design rather than set screws, creating a uniform, concentric grip on the conduit for a mechanically secure joint.
  • Rain Tight Construction: Built to be rain tight, this coupling helps keep moisture out of the raceway, supporting use in outdoor and exposed EMT installations.
  • Continuous Conduit Protection: Joins EMT conduit sections into a single, uninterrupted raceway that safeguards conductors from physical damage and environmental exposure.
  • Simplified Installation: The compression coupling design allows for a straightforward connection process during new installations, extensions, or repairs of 3/4" EMT conduit runs.
  • Durable Fitting Design: Manufactured as a dedicated EMT compression coupling for long-term, reliable performance in demanding electrical environments.

Arlington Industries 830RT – Frequently Asked Questions

1) Can I use an Arlington rain tight EMT compression coupling outdoors or in a wet location?
Yes. The Arlington 831RT and its sizes are rain tight compression couplings, built to keep moisture out of the raceway on outdoor and exposed EMT runs. A standard set screw coupling is not suitable there. Use these where the run is exposed to weather, and keep the compression nuts tightened fully to seat the seal.
2) What EMT trade sizes do Arlington RT compression couplings come in?
Three sizes: 1/2 inch is the 830RT, 3/4 inch is the 831RT, and 1 inch is the 832RT. Each is sized for that EMT trade size only, so match the coupling to the tubing you are joining. There is no reducing version among them.
3) Compression or set screw coupling for an EMT run, which one do I need?
Set screw couplings are for dry indoor work only. Compression couplings like the Arlington RT series clamp concentrically around the tube wall, so they hold alignment better and, in the rain tight version, seal the joint against water. If any part of the run is outdoors, exposed, or in a damp area, go compression rain tight. Indoors and dry, a set screw fitting is the cheaper and quicker choice.
4) Are these Arlington EMT couplings steel or die cast zinc?
Steel. That matters for a couple of reasons: steel fittings hold up better to impact on exposed industrial runs, and they keep the bonding path consistent with steel EMT. Specs that call out steel fittings rather than zinc die cast will accept them.
5) Can I use the 831RT to repair a damaged section in the middle of an existing 3/4 inch EMT run?
Yes, that is one of its normal uses. Cut out the damaged length, drop in a replacement piece of 3/4 inch EMT, and couple each end. Because it is a compression fitting rather than a threaded one, you do not have to rotate the conduit to make up the joint, which is what makes mid-run splices and extensions workable.
6) Will a rain tight EMT compression coupling work on rigid or IMC conduit?
No. These are EMT couplings, sized to the outside diameter of electrical metallic tubing. Rigid and IMC are threaded and have a different wall and OD, so they need threaded couplings instead. Use these only where the run is EMT on both sides of the joint.
