Topaz Lighting 252SRT Rigid/IMC Raintight Compression Coupling, Zinc-Plated Steel

The Topaz Lighting Rigid/IMC Raintight Compression Coupling is a zinc-plated steel fitting engineered to extend conduit runs by joining two lengths of unthreaded Rigid or IMC conduit of equal size. This coupling is available in 3/4" and 1" trade sizes, and its compression-type connection delivers a secure, raintight seal suitable for wet locations without the need for threading. The EZ-slip-on design eliminates disassembly during installation, saving labor time on the job site. cULus listed and compatible with UL6 Rigid steel conduit, these couplings are a reliable choice for professional electrical installations that demand a weatherproof, code-compliant joint.

Key Features

  • Trade Size: Available in 3/4" and 1" sizes for use with standard unthreaded Rigid or IMC conduit systems.
  • Durable Construction: Zinc-plated steel body provides corrosion resistance and long-lasting mechanical strength.
  • Compression-Type Connection: Compression fitting design creates a raintight seal without threading, ensuring a secure and weatherproof joint.
  • EZ Slip-On Design: Labor-saving installation with no disassembly required, reducing time and effort in the field.
  • Conduit Compatibility: Suitable for use with unthreaded Rigid and IMC conduit of equal size on both sides of the joint.
  • Wet Location Rated: Suitable for wet locations, making these couplings appropriate for outdoor and exposed conduit runs.
  • Finish: Zinc-plated steel for enhanced corrosion protection.

Topaz Lighting 252SRT – Frequently Asked Questions

1) Can I use the Topaz 252SRT coupling on threaded rigid conduit, or does it only work on unthreaded ends?
The 252SRT is a compression coupling, so it grips the outside of the conduit and needs unthreaded Rigid or IMC ends. That is the point of it: you can cut a length of rigid in the field and join it without cutting threads or breaking the run apart. If both ends of your joint are already threaded, a compression coupling is the wrong fitting, a threaded coupling is what you want there.
2) Is the Topaz 252SRT raintight compression coupling approved for outdoor and wet locations?
Yes. It is raintight and suitable for wet locations, and it is cULus listed, so it can go on exposed outdoor conduit runs, rooftop raceways and washdown areas. The compression seal is what makes the joint weatherproof without threading.
3) What trade sizes does the Topaz 25 Series rigid raintight compression coupling come in?
Two: 3/4 inch, ordered as 252SRT, and 1 inch, ordered as 253SRT. Both sides of the coupling take the same trade size, so it joins equal-size conduit only. If you are stepping from 3/4 to 1 inch you need a reducing fitting, not this coupling.
4) Do I have to take the coupling apart to install it on an existing conduit run?
No. The EZ slip-on compression design goes on without disassembly, so you slide it over the conduit end and tighten. That matters most on repairs and extensions where the run is already supported and you cannot spin a threaded coupling onto it.
5) How many Topaz 252SRT couplings come in a box?
They are packed 100 per unit, which is the standard way these get bought for a raceway job rather than a one-off repair. Worth knowing before you order for a single fix.
6) Is zinc-plated steel good enough for an exposed outdoor conduit coupling, or should I be looking at something else?
The 252SRT body is zinc-plated steel, which gives corrosion protection for normal exposed and wet-location work alongside standard galvanized rigid and IMC. For heavy chemical or coastal-splash environments, most specs call out a PVC-coated or stainless fitting instead. For ordinary commercial, industrial and utility raceway outdoors, the zinc-plated steel matches the conduit it is joining.
