Solid Brass Filler Hoop #20021 - Antique Finish for Rayo, Miller & Central Draft Lamps

The Missing Piece for Your Vintage Kerosene Lamp — Solid Brass, Period-Correct Finish

If your Rayo, Miller, or Bradley & Hubbard lamp is leaking fuel or the filler cap won't seat properly, the filler hoop is almost certainly the culprit. This solid brass replacement hoop (#20021) threads directly into the font (fuel reservoir) of Central Draft style kerosene lamps, restoring a leak-free seal and the authentic look your lamp deserves. The warm antique brass finish blends seamlessly with aged lamp patinas — no bright, out-of-place polish here.

What Does a Filler Hoop Do?

The filler hoop is the threaded collar that sits in the top opening of your lamp's font. It provides the threads the filler cap screws into and creates a stable, level sealing surface. A worn or missing hoop means fuel evaporation, spills, and potential safety hazards — this replacement fixes all of that.
