Topaz Lighting 477S – Frequently Asked Questions

1) What size liquidtight flexible conduit does the Topaz 471S straight connector fit?
The Topaz straight liquidtight connector is sold by trade size, and the 471S is the 1/2 inch. The rest of the family runs 3/4 inch (472S), 1 inch (473S), 1-1/4 inch (474S), 1-1/2 inch (475S), 2-1/2 inch (477S), 3 inch (478S) and 4 inch (480S). Match the trade size of the liquidtight flexible conduit you are terminating, not the wire size or the knockout you are landing in.
2) Is there a 2 inch Topaz straight liquidtight connector?
The straight liquidtight connector family runs 1/2, 3/4, 1, 1-1/4, 1-1/2, 2-1/2, 3 and 4 inch. There is a gap between 1-1/2 inch (475S) and 2-1/2 inch (477S), so a 2 inch liquidtight run needs a different fitting. Do not try to force a 1-1/2 inch body onto 2 inch conduit; the sealing gland is cut for one trade size only.
3) Will this connector work with regular flexible metal conduit or with EMT?
No. This is a liquidtight fitting, and the gland compresses on the jacketed outer cover of liquidtight flexible conduit. Standard FMC (Greenfield) has no jacket for the gland to seal against, and EMT is rigid tubing that takes a set screw or compression connector instead. Use it only on liquidtight flexible conduit of the matching trade size.
4) Will a malleable iron liquidtight connector hold up in a wet or wash-down area?
The body is malleable iron, which is the heavier-duty choice over die-cast zinc or nylon for industrial and outdoor equipment connections, and it is what you want where the fitting takes physical abuse from carts, hose, or vibration. It is a liquidtight fitting, so the gland and sealing ring do the water work, not the metal. In a chemical wash-down or coastal environment where iron corrodes, a plated iron or a nonmetallic liquidtight connector is usually the better call.
5) What does insulated throat mean on a liquidtight connector, and do I still need a bushing?
The insulated throat is built into the connector, so the edge the conductors ride over as you pull them in is already smooth and non-abrasive. That is the point of the feature: no separate insulating bushing goes on the inside of the box for conductor protection. It does not change how the fitting seals or how it grounds; it protects wire insulation during the pull and afterward under vibration.
6) How many Topaz liquidtight connectors come in a box?
Pack size is 100 fittings. That is a contractor or distributor quantity, sized for stocking a truck or a job trailer rather than a single repair. If you are buying for one motor connection or one rooftop unit, plan for the case quantity when you order.
7) Can I standardize one Topaz liquidtight connector part across a facility?
For MRO stocking, the practical approach is carrying the sizes your equipment actually uses rather than one part number. Most motor, HVAC unit and disconnect whips land in 1/2 inch (471S) and 3/4 inch (472S), with 1 inch (473S) covering larger feeders; the 2-1/2 through 4 inch bodies (477S, 478S, 480S) are service and large-equipment sizes you stock only if you have them. All share the same malleable iron body and insulated throat, so the install method is identical across the range.
8) Does the Topaz liquidtight connector come with a locknut and sealing ring?
Order the fitting by its trade size and check the sealing ring and locknut against what your installation needs; the sealing ring is what makes the enclosure side of the joint liquidtight at the knockout, and it is a separate consideration from the gland that seals on the conduit. For a raintight or wash-down enclosure, the enclosure-side seal is the part people forget.
