Crouse-Hinds 191SA Aluminum 3-Piece Conduit Coupling, 3/4-Inch

The Crouse-Hinds 191SA is a 3/4-Inch aluminum 3-piece conduit coupling engineered to join sections of rigid conduit where a standard threaded coupling cannot be rotated into place. Built from durable, lightweight aluminum, this coupling is a staple for electricians working in tight raceway runs, retrofit projects, and situations where existing conduit ends are fixed and cannot be turned. Its 3-piece design allows the coupling to be assembled around the conduit ends in place, making it an essential fitting for maintenance work, repairs, and new installation alike. When a run of rigid conduit needs to be repaired or extended but the fixed conduit ends cannot be spun to thread a conventional coupling, the 191SA solves the problem by breaking the coupling body into three separate pieces that can be positioned around the conduit ends and then assembled and tightened in place, restoring a secure, code-compliant mechanical and electrical connection without having to cut, re-thread, or replace the existing conduit run.

Key Features

  • Trade Size: 3/4-Inch sizing for compatibility with standard 3/4-Inch rigid conduit runs.
  • Durable Construction: Aluminum body offers a lightweight yet corrosion-resistant alternative to steel fittings, well suited for a wide range of electrical environments.
  • 3-Piece Design: Allows the coupling to be installed around conduit ends that cannot be rotated, simplifying repairs and additions to existing conduit runs.
  • Threaded Connection: Provides a secure, code-compliant mechanical and electrical connection between conduit sections.
  • Field-Friendly Assembly: The multi-piece body can be positioned and tightened around fixed conduit ends without disturbing adjacent fittings or requiring the conduit to be cut.
  • Professional-Grade Fitting: Manufactured by Crouse-Hinds, a trusted name in electrical conduit fittings for commercial and industrial applications.

Crouse-Hinds 191SA – Frequently Asked Questions

1) How do you couple two rigid conduit ends that can't be turned?
That's exactly the job the Crouse-Hinds 191SA is built for. A standard threaded coupling has to be spun onto one conduit end and then onto the other, which is impossible when both ends are fixed. The 191SA breaks the coupling body into three separate pieces that you position around the two conduit ends and then assemble and tighten in place, giving you a threaded mechanical and electrical connection without cutting, re-threading, or pulling out the existing run.
2) What conduit size does the Crouse-Hinds 191SA coupling fit?
It's a 3/4 inch trade size fitting, so it joins standard 3/4 inch rigid conduit. For any other trade size in a run you'll need the matching size of three-piece coupling, not this one.
3) Is the 191SA aluminum or steel, and does the material matter for my run?
The 191SA body is aluminum, which keeps the fitting light and corrosion resistant compared with a steel fitting. It matters on two counts: aluminum suits damp or corrosive environments where plated steel tends to rust, and for dissimilar metal reasons most electricians keep the fitting material consistent with the conduit they're working on. If your raceway is aluminum rigid conduit, this is the matching three-piece coupling.
4) Should I use a three-piece coupling or just a threaded union on a conduit repair?
Pick based on whether the conduit can rotate. If one end is free to spin, a conventional threaded coupling is faster and cheaper. If both ends are locked in by boxes, straps, or adjacent fittings, a three-piece like the 191SA is the fitting that works, because it assembles around the ends rather than threading on from one side. That's why it shows up most on repairs, retrofits, and extensions of existing rigid runs.
5) Does the 191SA need threaded conduit ends?
Yes. This is a threaded fitting, so both conduit ends have to carry standard rigid conduit threads for the coupling to pull up tight and give you a solid mechanical and electrical connection. It saves you from re-threading long runs, but it does not work on unthreaded or cut-off plain ends, those still need to be threaded or handled with a compression type fitting.
6) Can I install the 191SA without disturbing the fittings on either side?
That's the point of the design. The three pieces are positioned and tightened around the fixed conduit ends in place, so adjacent fittings, straps, and boxes stay where they are and the conduit doesn't have to be cut back. It's a common pick for maintenance and MRO work in occupied commercial and industrial buildings where tearing out a raceway isn't an option.
7) What is the exact part number to order for the Crouse-Hinds three-piece aluminum coupling in 3/4 inch?
Order Crouse-Hinds 191SA. That single manufacturer part number covers the 3/4 inch aluminum three-piece conduit coupling, and it ships as a complete fitting, all three pieces together.
