Abstract: A fitting has a first housing including a first body and a second body. The first body defines a first channel and a second channel, and second body defines a third channel that is co-planar with the first channel and a fourth channel that is co-planar with the first channel. First bearings are disposed within the first channel and the third channel, where the first bearings rotatably coupled the first housing to the second housing. Additionally, second bearings are disposed within the second channel and the fourth channel, the second bearings rotatably coupling the first housing to the second housing. A plug couples to the first housing, a gasket is disposed between the plug and the first housing, and a passage is defined at least in part by the first housing, the second housing, and the plug.

Abstract: A hot oil/fat fire extinguisher, comprising a frame which supports a smothering material in a horizontal plane and a handle which allows the safe and effective application of the smothering material to a container of burning fat/oil. When not in use it may be stored in a holder which can be wall mounted. In the event of a container of fat/cooking oil igniting, the extinguisher can be removed from the holder by using the handle and presents a smothering material of a size and shape suitable for covering the container of burning fat/oil. This is placed over the container in the manner prescribed in the instructions of use, depriving the burning surface of air and achieving extinction.
