type i - question # 9\nwhich of the following best describes low loss fittings on refrigerant recovery devices used to recover cfcs, hcfcs, and hfcs?\na they can be either manually closed or automatically closed when disconnected to prevent loss of refrigerant from hoses.\nb they are used to connect the recovery device to an appliance and leak only small amounts of refrigerant during use.\nc they are used to connect the recovery device to an appliance and must be discarded after each use.\nd they eliminate oil loss during recovery.

Answer

Brief Explanations:

Low - loss fittings on refrigerant recovery devices are designed to prevent refrigerant loss from hoses when disconnected. They can be manually or automatically closed. Option B is incorrect as they are meant to prevent significant refrigerant loss, not just allow small leaks. Option C is wrong as they are not single - use. Option D is incorrect as they are for refrigerant loss prevention, not oil loss prevention.

Answer:

A. They can be either manually closed or automatically closed when disconnected to prevent loss of refrigerant from hoses.
