| | .gif) | FULL FACE GASKET
A full face or bolt hole gasket consists of five measurements. First, measure the Inside Dimension (I.D.) and Outside Dimension (O.D.) just like you would a ring gasket. Then, count the number of Bolt holes and also measure the diameter of the bolt holes. The final dimension is the Bolt Circle. The bolt circle is most difficult and confusing dimension to measure and understand for most people. It doesn’t have to be. The Bolt Circle is the measurement from the center point of one of the bolt holes to the center point of the bolt hole directly opposite of it. An easier way to measure the bolt circle without having to eyeball the center of the bolt hole, is to measure from the left side of one bolt hole to the right side of the bolt hole directly opposite it. | |

The most common shape for a boiler gasket is an ellipse. Elliptical boiler gaskets are called handway and manway gaskets for small and large gaskets respectively. When measuring an elliptical boiler gasket, you need four dimensions: the two inside diameters, the width and the thickness of the gasket. Usually, standard boiler gasket are made of ¼" rubber. The first inside dimension consists of the length from top to bottom of the inside of the gasket. The second inside dimension is the length from right to left on the inside of the gasket. There are other shapes for boiler gasket such as an oblong, a pear, or a round shape. If you have any questions on how to measure a particular gasket just ask a member of Hennig Gasket staff. Also, please feel free to stop in with a sample of the old gasket or send Hennig Gasket a sample through the mail. | |
