an O-ring, a good fit is critical. O-rings are measured in millimetres. Place the O-ring on a clean, flat, level surface. Determine the inside diameter. Use a ruler to measure from one inner edge to another. To measure the outside diameter, use a ruler to measure from one outer corner of the O-ring to the other outer corner. Measure cross section. Place the O-ring into a vernier calliper. Lightly clamp the jaws of the calliper onto the O-ring, but do not compress it. Record the thickness of the ring (the cross section). If you only have 2 of the O-ring diameters then you can determine the third diameter with the following equations: Measurements: Outside Diameter (OD) = Inside Diameter + (2 x Cross Section). Inside Diameter (ID) = OD - (2 x CS). Cross Section (CS) = OD - ID, Ã· 2. If the o-ring is cut, measure the cross section (thickness) of the O-ring and the length. Converting Length to Inside Diameter: Length Ã· 3.142 = circumference. Circumference - CS = ID.
Below is another chart that will help you to determine your size using the inside diameter of the ring in millimeters. This is often a way to double check your findings from the paper method. You can also use a ring you currently wear and cross check it with the below chart.lease sign in to vote on this Guide. This chart will help you determine the ring size you will require. Use a tape measure, piece of string or piece of string around your finger, where you will be wearing the ring. Mark the string or paper where it overlaps to form a full circle.
