I would like to re-use an output filter that formed part of a now broken Jun-Air compressor. However, I can't figure out the connector type that I need to do so. I would have assumed a CGA connector appropriate to air however I can't make the outside thread diameter (16.7 mm/0.657") and the thread pitch (difficult to measure but about 0.95 mm/0.037" so > 25 TPI) match. A picture with dimensions is included below: it is the thing on the far right that I'm trying to obtain, the bit on the output of the Jun-Air compressor where the filter attached. Since it is effectively internal to the compressor design (the user only attaches to the 6 mm push-fit connector on the other side of the filter) it could, of course, be of their own design, but that would seem unnecessary. All advice welcomed.
