Plant 3D: Catalogs and Specs - Make a new Spec 

You want to add Gaskets and Bolts?

Is this for an OLET?

@@technexus no for coupling branch. I tried but with coupling branch cells become red. Is there any solution for this

In the Branch Table, you need to add the fittings that line up with what was given to you on the paper spec. If the paper spec doesn't have a branch table, you'd need to ask the engineer for it. This gives me an idea to do another video on Branch Tables

In the toolbar menu at the top of the Catalog Editor, under "Catalogs" then the last entries are for Imperial or Metric values.

technexus thanks
