O-Ring Cord to make your own O-rings and gaskets

Please note: Priced & sold per foot. If ordering more than one foot (of the same size), the cord will come as one whole length.

How to calculated O-Ring cord length needed:

( ( OD + ID ) / 2 ) x Pi = length Pi=3.14159

ID + CS X 3.14159= Cut Length

Determine the cut length if you know the inside diameter and the cross section:

(Inside Diameter + 1X the Cross Section) * 3.142 = Cut Length
