Bridgeport Fittings 1063 Galvanized Steel Reducing Washer, 1" to 3/4"

The Bridgeport Fittings 1063 Galvanized Steel Reducing Washer steps a conduit opening down from a 1" trade size to 3/4", letting electricians install smaller 3/4" conduit connectors, couplings, and locknuts into an existing 1" enclosure, panel, or box knockout without redrilling or replacing hardware. Machined from galvanized steel, this reducing washer resists rust and corrosion while providing a stable, flush transition between mismatched conduit and knockout sizes. It's a practical, low-cost solution for electricians and contractors working with mixed conduit sizes on commercial, industrial, and residential jobs where a larger 1" knockout needs to accept a smaller 3/4" conduit fitting, helping maintain a properly sized opening around the conduit run.

Key Features

  • Trade Size: Reduces a 1" knockout or opening down to accept 3/4" conduit fittings, connectors, and locknuts.
  • Durable Construction: Galvanized steel construction resists rust and corrosion for long-term reliability across a range of installation environments.
  • Space-Saving Adapter: Lets installers reuse an existing 1" knockout with a smaller 3/4" conduit run instead of drilling and fitting a new opening.
  • Flush, Secure Fit: Sits between the conduit fitting and the enclosure or panel wall for a stable, properly sized transition around the reduced conduit opening.
  • Simple Installation: Drops into place between the fitting and knockout for a fast, tool-minimal installation that saves time on the job.
  • Compact, Low-Cost Adapter: Offers an economical alternative to replacing an entire conduit fitting or redrilling an enclosure to a smaller trade size.

Bridgeport Fittings BPF1063 – Frequently Asked Questions

1) Will a Bridgeport 1063 reducing washer let me run 3/4 inch conduit into an existing 1 inch knockout?
That is exactly what the 1063 does. It steps a 1 inch trade size opening down to 3/4 inch, so a 3/4 inch connector, coupling or locknut can land in a 1 inch enclosure, panel or box knockout without redrilling the can or swapping the fitting. The washer sits between the fitting and the enclosure wall.
2) Do I need one reducing washer or two when adapting a 1 inch knockout to 3/4 inch conduit?
Reducing washers are normally used in pairs, one on each side of the enclosure wall, so the 3/4 inch fitting is centered and the opening is closed on both faces. The Bridgeport 1063 is a single 1 inch to 3/4 inch washer, so order quantity accordingly for each knockout you are adapting.
3) Is the Bridgeport 1063 reducing washer OK for damp or corrosive industrial locations?
The 1063 is galvanized steel, which resists rust and corrosion, and it is used in commercial and industrial electrical work as well as residential. It is a plain reducing washer though, not a sealing gasket, so it does not make a knockout raintight or wet-location tight on its own.
4) Is a reducing washer better than a reducing bushing or drilling a new hole in the panel?
For a knockout that is simply one trade size too big, a reducing washer is the quickest fix: it drops in between the fitting and the knockout with minimal tools and no fabrication. Drilling or punching a new 3/4 inch opening means an unused 1 inch hole you then have to close off, and replacing the whole fitting to match the larger knockout costs more than the washer. Use a threaded reducing bushing instead when you need to change the thread size on a fitting or hub, not the size of a sheet metal opening.
5) Will the Bridgeport 1063 work with EMT and rigid conduit connectors?
The washer is sized by trade size, not by raceway type, so any 3/4 inch trade size connector or coupling, EMT or rigid, threaded or set screw, passes through it into a 1 inch knockout. The locknut still does the clamping; the washer just closes down and centers the opening.
6) How do I order the right Bridgeport reducing washer, and what is the part number for 1 inch to 3/4 inch?
The 1 inch to 3/4 inch galvanized steel washer is Bridgeport Fittings part number 1063. Reducing washers are ordered by the pair of sizes they bridge, so specify the knockout size first (1 inch here) and the fitting size you are reducing to (3/4 inch).
