Types of Rubber Gaskets and Seals

Rubber Gaskets and seals can be made in a wide variety of shapes and styles. The most common gaskets are round and can be supplied with or without holes. These are typically used for sealing two flanges.

If gaskets have holes for the flanges bolts to go through, they are called full faced Gaskets. Gaskets without holes are referred to as inner bolt circle gaskets (IBC) Washers or stub gaskets  

The position of the holes for the bolts in full faced gaskets, is referred to as either PCD (Pitch Circle Diameter) or BCD (Bolt Circle Diameter.)

Many rubber gaskets are made to sizes published in standard gasket tables. These are lists of gasket sizes suitable for different sizes of pipelines, or flanges, with different pressure ratings.

The most common standard tables are BS EN 12560 which superseded BS 1560, ASME B16.21, and BS10 1962 and BS EN 1514-2:2014.

We also manufacture many different variations of standard table gaskets, like the examples below, ensuring that you get exactly the right seal.
