Have an o-ring that you need to replace and you don’t know what size it is? Rubber Fab’s o-ring cone is the best solution for sizing o-rings when you are unsure of what to order. Slide the o-ring down the cone to see what size is needed. Makes for easy measuring as the numbers are printed directly on the cone. The cone also has slits near the base. Insert the o-ring to determine the cross section then slide the o-ring down the corresponding side.

O-Ring measurement cones are the ideal tool for quick and easy identification of standard AS568 O-Ring sizes. The base of the cone has 5 slots to determine the o-ring width. Just slide the o-ring over the cone to identify the corresponding dash #. Dash Numbers are permanently molded into steps around the cone for precise identification.

There is a simple way to measure an o-ring. Of course we suggest an o-ring cone to make sure that the size is exactly what you need. Formula to determine an o-ring diameter is: Cut length ÷ 3.1415 = xx – cross section = I.D. When quoting an o-ring, the following needs to be considered.
  1. Which AS568# number, I.D. x cross section, or O.D. cross section
  2. Material and Durometer needed (70 is standard)
  3. Compliance required (FDA, Class VI, ADI, 3A)
  4. Quantity is important. O-Ring pricing is quantity sensitive.
  5. What is the application?
  6. Application Temperature?
  7. Is the application static or dynamic? This is extremely important when quoting Detectomer® O-Rings.
