Thomas & Betts 3707 – Frequently Asked Questions

1) What does a Thomas & Betts 3707 reducing washer actually do on a conduit run?
The 3707 is a flat galvanized steel washer that reduces a 1-1/4 inch opening down to 3/4 inch. You use it when a box or enclosure knockout, or a fitting hub, is bigger than the conduit you are bringing into it. The washer takes up the difference so the smaller conduit or connector lands centered and tight instead of rattling in an oversized hole. It is made for rigid and IMC conduit systems.
2) Do I need one 3707 reducing washer or two per knockout?
Reducing washers are used in pairs, one on each side of the sheet metal, so the conduit or connector is held square and the opening is closed on both faces. Order the 3707 accordingly, and note that the part number covers a single washer, not a pair.
3) Can I use the 3707 reducing washer outdoors or in a damp location?
The steel is galvanized for corrosion resistance and the fitting is called out for indoor and outdoor use. Keep in mind a reducing washer is not a sealing device on its own; it closes down an oversized knockout mechanically, so if the enclosure has to stay raintight you still need the appropriate raintight hub or connector and sealing gasket at that entry.
4) Will the 3707 work with EMT or PVC conduit, or only rigid and IMC?
Thomas & Betts lists the 3707 as a rigid/IMC conduit fitting, so that is what it is built for. In practice the washer reduces the hole size, so what matters is the trade size of the threaded hub or connector passing through it: it takes a 1-1/4 inch opening down to 3/4 inch. If you are running EMT or PVC, specify a reducer or adapter made for that raceway type rather than assuming this one fits.
5) What is the manufacturer part number for the 1-1/4 to 3/4 inch Thomas & Betts reducing washer?
Thomas & Betts 3707. That single MPN covers the 1-1/4 to 3/4 inch galvanized steel reducing washer, and it is the number to quote to a distributor. There are no finish or size options under it to specify.
6) What material is the Thomas & Betts 3707 washer, and will it hold up in an industrial plant?
Steel with a galvanized coating. That combination is what electrical contractors use in commercial and industrial conduit systems where the fitting may see moisture or wash-down splash, and it keeps the washer compatible with the steel raceway around it so you are not mixing dissimilar metals at the enclosure wall.
