Flat cotton wicking feeds liquid fuel up to the flame through simple capillary action. An old wick chars down over time and needs replacement when it no longer reaches the bottom of the oil reservoir. We size model 99963 for standard oil lamps that require a wide, flat strip of woven cotton.
Use these replacement strips with our burner model 31507 and liquid paraffin fuels like Lamplight Ultra-Pure or Medallion Lamp Oil. A fresh piece of 3/4 inch cotton restores proper fuel delivery to your indoor oil lamp.
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.
