5、.In case of doubt, the German-language original should be consulted as the authoritative text.Supersedes April 1984 edition.All dimensions are in millimetres.1 ScopeThis standard specifies the design and dimensions of taper stud tees (stud run) with type W port as inDIN 3861, for use in compression

6、coupling assemblies.In combination with fittings as in DIN EN ISO 8434-1, series L and S fittings as specified here areinterchangeable with DIN 3944 male stud tees.NOTE: Tightness of the assembly cannot be guaranteed since this is a function of the medium conveyed,the working pressure and temperatur

7、e, and the combination of materials used. Therefore, when designingcompression couplings as specified in this standard, use of a seal is recommended.Page 2DIN 3913 : 2001-042 Normative referencesThis standard incorporates, by dated or undated reference, provisions from other publications.
