Hygienic liner BS4825-4 IDF (International Dairy Federation).
This is a commonly used combination in piping systems, especcially where high hygiene standards are required; such as dairy and food production lines.
A complete IDF coupling connection consists of a male part, a liner, a slip nut and a gasket.
The materials, dimensions and maximum roughness of IDF couplings are standardized in the BS4825-4 standard.

Available sizes in this 3D CAD collection
STEP (.stp) 3D CAD file format
The CAD files are saved in the STEP (.stp) file format. That is an export/import file format recognized by all solid modeling programs.
After importing a step file into your software program, you can save it in the format of your program.
This allows you to build your own 3D CAD library with parts made by different software programs.
Programs that work excellent together with step files include: Autodesk Inventor, Solidworks, Fusion 360, Catia, Solid Edge.
Main dimensions according to the BS4825 part4 standard
Because the main dimensions are also laid down in the BS4825 standard, it was possible for us to make this 3D CAD collection. We only make 3D CAD models, we are not a fitting manufacturer or supplier. However, you can be sure that these 3D models have the same dimensions as the fittings "in real life".
High level of detail
We've put in as much detail as possible; our 3D models have a consistent quality.
Having these 3D files collections in your engineering toolbox, you can save a lot of time that you can use to improve your designs even more...
