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.
