These items are un-used forged Brass male female flare  to male flare fittings in various configurations (see variations chart)  and basically in almost new condition except for the fact that they have been held by Ex-Contractor as a Spares/Stock item along with other brass unions in trays, so they may have some minor cosmetic wear, such as light scratching or minor limited tarnishing and the odd forge mark. They are generally clean and sound as can be seen from the photographs, plus they were all purchased from the likes of Dean & Wood, HRP and NRS (Control Centre) U K Wholesalers so they are all good quality, substantial brass fittings  not like some of the current cheap foreign imitations. They are primarily designed for Refrigeration and Air Conditioning Systems. Theses items will be supplied loose as originally supplied by the manufacturer, but with the additional protection of a clean packaging bag.
