CUI replacement heater wicks are made in
England with the highest quality materials, sized
precisely for each heater - and that includes the
correct thickness! CUI wicks are made with
graphic infused fiberglass and an absorbent
cotton bottom, so they burn evenly and cleanly
for a long time. [Note: some wicks are not
graphite infused by design. Wick #39 is cotton to
replace Perfection wick #500.]
