Beschrijving
Long weld stub in stainless steel with DN 63 ISO-K connection is a vacuum and laboratory equipment fitting intended for permanent integration into process or apparatus lines. The component provides a weldable stub geometry on one side and a standardised DN 63 ISO-K flange interface on the other, supporting secure coupling to matching ISO-K hardware in pump systems, chambers and related laboratory installations. Manufactured by WELCH, the stainless steel construction is suited to environments where mechanical strength and compatibility with common vacuum flange practices are required. As an accessory and spare part for laboratory devices, the long weld stub helps extend or adapt existing DN 63 ISO-K ports when a welded transition is preferred over a demountable joint. The compact single-piece format simplifies stock-keeping for maintenance teams and equipment builders who standardise on ISO-K DN 63 connections. Use is straightforward within the scope of the stated designation: select the stub where a stainless steel long weld transition to DN 63 ISO-K is specified by the apparatus design.
