When selecting the correct size, here are some brief notes to keep in mind.
  • The Diameter is the distance across the circle and the Circumference is the distance around the circle.
  • The diameter on the outside of the pipe (“OD” for short) can vary significantly from the inside diameter of the opening (“ID” for short). Firwin Wrap is ALWAYS based on the Outside Diameter (“OD”).
  • Sometimes it is easier to measure a Diameter and sometimes it is easier to measure a circumference. Our part description includes both the Outside Diameter (“OD”) and the Outside Circumference (“Circ.”). Note that the “Circ.” dimension is rounded off to the closest ¼”.
