Zero- Length Reducer Flanges (Standard)
Adapt two different-size knife-edge flanges that need to be bolted together.
Reducer Flange Features
- All small flanges have blind tapped bolt holes — most large flanges have through-holes (where the two flanges have similar diameters, both are tapped)
- Part numbers ending with the letter "T" represent double-tapped flanges
- The maximum I.D. of the small flange limits the bore
