Gas cylinders with collet connection

Collet

— cylinders with such a connection have a thin stem with an exhaust valve on top, which is fixed when installed in the clamp (collet) of the burner. This method is well suited for "tourist stove" type burners, where the cylinder is installed in a special compartment of the body; for other installation methods, it is not reliable enough. Also note that collet cylinders have relatively thin walls. However, given the specifics of their application, this is hardly a serious drawback, although it requires some accuracy.
