There are two options for finding your sanitary fitting dimensions:

Option 1 | Measure the Outside Diameter (OD) of the tube end:

• Lay your piece down on a sheet of paper and trace a circle around the outside of the tube end
• Measure the diameter of the traced circle to determine your piece’s Outside Diameter (OD)

See the included video or reference the guides below to find your sanitary fitting size.

Option 2 | Measure the Outside Diameter (OD) of the flange end:

• Lay your piece down on a sheet of paper and trace a circle around the outside of the flange end
• Measure the diameter of the traced circle to determine the Outside Diameter (OD) of the flange end
• Note: 1″ & 1 1/2″ Sanitary Fittings have the same flange OD. To determine your size, also note the Inside Diameter (ID)

See the illustration below and the associated graph to determine your sanitary fitting size.

Next, use your Outside Diameter (OD) measurement to determine fitting size:

The flange size, which is the same measurement as the outside diameter (OD), is not equal to the sanitary fittings size. In order to determine the correct sanitary fitting size required, please refer to the measurements table or note the Inside/Outside diameters labeled in the illustration below.
