Replacement Dietz Brand Filler Caps. Your choice of color: Blue or Black. Fits any Dietz brand oil lantern with a filler cap.
For threaded hole of appoximately 13/16''.
Note: These Deitz filler caps are designed with the current tooling and may not fit older model Dietz lanterns. Dietz changed the threading pattern in 1956, so lanterns made before that time will require a different filler cap.
