Zero- Length Reducer Flanges (Metric)

These flanges 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 "M" represent double-tapped flanges
• The maximum I.D. of the small flange limits the bore

NOTE:

• Flanges listed below with the nominal O.D. of the smaller flange given first. (The combination's "true" O.D. is that of the larger flange.) The part number is the flange diameter expressed as decimal numbers, giving the large flange first.
• TH ≡ Through Hole
• Both sets of bolt holes are tapped. The smaller thread size applies to the smaller flange mounting where applicable.
