How to Measure a Gasket
Flange Gaskets
The PCD (pitch circle diameter)
The PCD is the measurement between the centres of oposite holes. This can be measured from the inside of one hole to the outside of the other, providing the hole diameters are equal.
IBC (Inner Bolt Circle) Gasket
The IBC gasket is as the drawing above, but only has an OD and ID (with no holes) and often sits inside the holes.
