This DIN connection comes in a Light Series (DKL/DKOL) and a Heavy Series (DKS/DKOS). Some thread sizes in each series are the same, but the Tube OD of the Heavy Series is smaller and has a thicker tube wall. Because the tube and sealing cone are different sizes, Light and Heavy Series are NOT interchangeable.
The DIN male 24° internal cone seat will seal with flareless female swivel fittings. These female fittings use either a spherical nose (DKL/DKS) or an O Ring seal (DKOL/DKOS) located on their outward facing 24° cone. Female DKL sizes
up to and including M26 have a universal 24°/60° cone and can be used in place of female DKM fittings with 60° cone.
The same male also mates with the DIN system Metric Tube, Tube Nut and Compression Olive (Cutting Ring). Tightening of the female nut compresses the olive causing it to cut into the tube, thereby forming a seal between the tube, olive and 24° male cone.
The same male used with a metal Bonded Seal will mate with a DIN 3852-1 metric threaded port with spotface.
DKM 60° CONE SEAT
The DIN male 60° internal cone seat will mate with
DKL/DKM female universal 24°/60° cone fittings up to and including size M26 and DKM female 60° cone fittings from size M30 up.
*These DKL Light Series Female Connections can be used in place of DKM Female. NOTE: in above tables, pitch is included in DASH Size.
For HOSE COUPLINGS and most ADAPTORS, pitch is not included in the DASH Size.
