The newer style Hasselblad CF T* lenses the PC sync connection has a hexagonal collar and a small "O" ring between the collar and the female contact. Paramount's Long Tip and Gold Tip PCs are long enough to get into the PC to make good contact. Their tips are tapered and they will push aside the "O" ring. Other tips only go into the lens part way and scrape against the O ring, which in time causes it to wear out.
NOTE: Paramount Long Tip PC cords work with all cameras with PC fittings: all 35mm cameras, newer Hasselblad lenses, Hasselblad CF/CFi/CFE and Bronica cameras
