Topaz Lighting 1072 – Frequently Asked Questions

1) What size PVC conduit does the Topaz 1072 expansion coupling fit?
The Topaz Lighting 1072 expansion coupling family covers trade sizes 3/4 inch through 4 inch. Orderable sizes are 3/4 inch (model 1072), 1 inch (1073), 1-1/4 inch (1074), 1-1/2 inch (1075), 2-1/2 inch (1077) and 4 inch (1080). Match the coupling to the trade size of the conduit run, not to the outside diameter you measure.
2) Will a Schedule 40 expansion coupling work on my Schedule 80 PVC conduit run?
Yes. The Topaz 1072 coupling is built for use with both Schedule 40 and Schedule 80 PVC conduit, so a contractor running Schedule 80 in an exposed or outdoor location can use the same fitting. Schedule 40 and Schedule 80 share the same outside diameter at a given trade size, which is why one coupling serves both; the difference is wall thickness.
3) Do I actually need an expansion coupling on an exposed PVC conduit run, or can I just glue it straight through?
PVC moves a lot with temperature, and a solvent-welded run with no relief pushes that movement into the fittings, boxes and straps. An expansion coupling like the Topaz 1072 takes up that length change so the run is not stressed. The decision point is exposure: outdoor, rooftop, unconditioned or above-grade runs with a wide temperature swing are where these belong. A short interior run in conditioned space usually does not need one.
4) How does the Topaz 1072 connect to the conduit, and do I still solvent weld it?
The 1072 has a male terminator adapter end, so one side threads or lands as an adapter into the enclosure or fitting, and the conduit side takes the conduit. It is a two-piece coupling: the inner barrel slides in and out of the outer body as the run grows and shrinks, so that side must stay free to move rather than being locked down.
5) Will a PVC expansion coupling hold up outdoors and in a corrosive environment?
The 1072 is molded from noncorrosive PVC, so it resists moisture and chemical attack the way the conduit itself does, which is why PVC gets specified in wash-down areas, coastal sites and wastewater plants over steel. Lubricated seals inside the coupling keep the sliding joint moving instead of binding as the run cycles.
