7660-3661 Coleman OEM Observation Burner Cap With Fire Glass and Gasket

Well made though the cap could be a little deeper : the first threads of the well on my furnace were a bit worn and tapered so the cap wouldn't grab firmly ;without the lens and gasket it grabbed perfectly , so the extra depth would have been useful .As it was , a few wraps of hi-temp aluminum tape improved the grip enough to seal . Understand the parts had to be manufactured but the shipping cost seemed excessive . Will recommend to anyone who needs this .
