There are two options for finding your tri-clamp gasket dimensions:

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

• Lay your gasket down on a sheet of paper and trace a circle around the outside
• Measure the diameter of the traced circle to determine your tri-clamp gasket’s Outside Diameter (OD)

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

Option 2 | Measure the Inside Diameter (ID) of the gasket:

• Lay your gasket down on a sheet of paper and trace a circle around the inside of the gasket
• Measure the diameter of the traced circle to determine the Inside Diameter (OD)
• Note: 1″ & 1 1/2″ tri-clamp gaskets have the same Outside Diameter but different Inside Diameters.

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

Use your Outside Diameter (OD) or Inside Diameter (ID) measurement to determine your tri-clamp gasket size:

In order to determine the correct tri-clamp gasket size required, please refer to the measurements table or note the Inside/Outside diameters labeled in the illustration below.
