O-Ring Weight Calculator

Two important aspects when sourcing o-rings are 1) the cost of o-rings and 2) the cost to ship o-rings. With shipping costs relying heavily on total package weight, Global O-Ring and Seal developed the O-Ring Weight Calculator. The O-Ring Weight Calculator determines the volume of the o-ring, which is then multiplied by the specific gravity (density) of the material to return the approximate weight. With this interactive tool, the total o-ring weights for any quantity of NBR, Viton, Silicone, EPDM, HNBR, AFLAS, and more can be calculated instantly. Start calculating below!

 

 

How to Use the O-Ring Weight Calculator

With AS568 Dash Number

  1. Select o-ring material.
  2. Input AS568 Dash Number in the Size, then enter a value for Quantity.
  3. Instantly see Piece Weight and Total Weight render in lbs or kg.
  4. Change quantities as needed to see Total Weight update instantly.

With Dimensions

  1. Select o-ring material
  2. Toggle between Inches (IN) and Millimeters (MM).
  3. Input Cross Section and Inside Diameter.
  4. Enter a value for Quantity.
  5. Instantly see Piece Weight and Total Weight render in lbs or kg.
  6. Change quantities as needed to see Total Weight update instantly.

Note: This tool is to be used for reference only and will not yield precise unit weights. The most important factor for calculating o-ring weight is the density or specific gravity of the rubber compound. For simplicity purposes, we are using typical or average specific gravities for various material families.
