Clear glass chimneys protect the flame from drafts and draw air up past the wick. When an original chimney cracks or chips, this spare restores the draft path on large oil lamps. We form the 417B with an outward flare at the top rim to direct heat away from the body.
This replacement chimney fits large oil lamps that require a 3 inch base opening. Pair the glass with our Ultra-Pure or Medallion lamp oil in the lamp reservoir for steady burning during power outages.
The figures in the table above are the ones to go by when you order a spare part, and our parts finder puts every chimney and wick measurement side by side.
