Topaz Lighting 52SLT Liquidtight to Rigid Combination Coupling, Zinc-Plated

The Topaz Lighting 52SLT Liquidtight to Rigid Combination Coupling delivers a secure, enduring liquidtight connection between liquidtight conduit and rigid conduit systems, and can also terminate an external bonding conductor running parallel to the conduit. Built with a zinc-plated finish for added resilience and corrosion resistance, this combination coupling is available in trade sizes from 3/4" to 2" and is UL rated for use in wet locations, making it a dependable choice for professional electrical installations.

Key Features

  • Trade Size Range: Available in trade sizes from 3/4" to 2" to accommodate a wide variety of liquidtight and rigid conduit installations.
  • Combination Design: Connects liquidtight conduit to rigid conduit in a single fitting, simplifying transitions between conduit types.
  • Bonding Conductor Termination: Capable of terminating an external bonding conductor that runs parallel to the conduit, supporting grounding and bonding requirements.
  • Durable Construction: Zinc-plated finish provides additional resilience and corrosion resistance for long-lasting performance in demanding environments.
  • Wet Location Rated: UL rated for use in wet locations, suitable for both indoor and outdoor electrical installations.
  • Liquidtight Integrity: Engineered to ensure an enduring, liquidtight seal that protects conductors from moisture and environmental contaminants.

Topaz Lighting 52SLT – Frequently Asked Questions

1) Can I use a Topaz 52SLT combination coupling to connect liquidtight flexible conduit directly to rigid conduit?
That's exactly what the fitting is for. The Topaz liquidtight to rigid combination coupling makes the transition in one piece: liquidtight flex on one end, rigid conduit on the other, so you don't need a box or a pair of separate connectors at the changeover point. Common spots are a rigid run dropping into a length of liquidtight at a motor, a rooftop unit, or a piece of machinery that vibrates.
2) What trade sizes does the Topaz liquidtight to rigid combination coupling come in?
Orderable trade sizes are 3/4 inch (52SLT), 1 inch (53SLT), 1-1/4 inch (54SLT), 1-1/2 inch (55SLT), and 2 inch (56SLT). Both ends of a given fitting are the same trade size, so a 1 inch coupling ties 1 inch liquidtight to 1 inch rigid. If your rigid run and your flex are different trade sizes, you need a reducing arrangement rather than this coupling.
3) Is the Topaz 52SLT combination coupling rated for outdoor and wet locations?
Yes. The coupling is UL Listed and rated for wet locations, which covers exterior walls, rooftops, wash-down areas, and below-grade transitions where the fitting will see standing water or weather. The zinc-plated finish is what carries the corrosion resistance on that duty.
4) Can I land an external bonding jumper on a Topaz liquidtight combination coupling?
Yes. The combination coupling will terminate an external bonding conductor run parallel to the conduit, so where the liquidtight run needs a supplemental equipment grounding conductor on the outside of the raceway, the jumper lands at the fitting instead of needing a separate ground bushing or clamp. That is the main reason to spec this version over a plain transition fitting.
5) Do Topaz 52SLT couplings come individually or do I have to buy a box?
They're packed 100 to a pack. That's a stocking quantity for a contractor or MRO crib standardizing on one trade size, not a one-off part for a single repair, so plan the order around a run or a fleet of similar terminations rather than a single fitting.
6) Will a liquidtight to rigid combination coupling work with EMT, or do I need something else?
This coupling is built for the liquidtight to rigid transition specifically, so the threaded side mates with threaded rigid or IMC. EMT is a thin-wall, unthreaded raceway and takes a set-screw or compression connector instead, so a run coming out of EMT needs an EMT to liquidtight fitting rather than this one. Same caution with a liquidtight run going into a box: that calls for a liquidtight connector, not a coupling.
7) Is a zinc-plated coupling good enough for a coastal or wash-down install?
Zinc plating is the corrosion protection on this fitting, and it's UL rated wet location, which covers weather-exposed and wet interior work. For heavy chemical or continuous salt exposure many specs call for a non-ferrous or PVC-coated fitting instead, so check what the drawing calls out before substituting this one into a corrosive-classified area.
8) What is the part number for a 1-1/4 inch Topaz liquidtight to rigid coupling?
54SLT is the 1-1/4 inch size in the Topaz SLT combination coupling family. The neighbors are 53SLT at 1 inch and 55SLT at 1-1/2 inch, so the number climbs by one as the trade size steps up through the range.
