enables the fi lling hose to be removed if the fi ller valve fails to close.
An integral back check in the adaptor prevents gas from escaping
in the event of a failure of the fi ller valve. The fi ller valve should be
repaired as soon as possible and the Type M570 removed from the
fi ller valve. Standard product temperature rating is -20 to 160°F /
