What are gaskets
Gaskets
| Materials Used | Applications |
Gaskets are used to create a static seal between two flanges faces, at various operating conditions, with varied pressure and temperature ratings. A gaskets fills the microscopic spaces and irregularities of the flange faces, and then it forms a seal that is designed to keep liquids and gases. Correct installation of damage-free gaskets and demage-free flange faces is a requirement for a leak-free flange connection.
If it would be technically possible, in order to manufacture flanges perfectly flat and smooth, and perfectly compatible with one another under all operating conditions, a gasket would not be necessary. But in normal practice it is not possible, because flange connections under ANY circumstances should be made. Small impurities and a small bit of dirt, is in practice not be avoided and therefore it is necessary to use a gasket.
Materials used:
Flange gaskets are made of various materials like:
-
Rubber
- Neoprene
- EPDM
- Nitrile
- EVA
- Silicone
- Cork and Cork Rubber
-
Closed Cell Foam
- Cross-linked Polyethylene
- PVC
- Plant Fiber
- Cellulose Fiber
-
Metal
- Steel

Types of flange gaskets:
Standard pipe flange gasket line includes two basic styles:
Both ring type and full face pipe flange gaskets are available in both low and high pressure options. |
How to measure pipe flange gaskets?
It is necessary to know the nominal pipe size and the gasket’s inner diameter and outside diameter.
Applications of Typical Flange Gaskets:
- HVAC (Heating, Ventilation, and Air Conditioning) Industry: Usually, flange gaskets used in this industry are made of different types of rubber. They are usually supplied with adhesive on one or both sides in various shapes like round (I.D. x O.D.), rectangular and square outside shapes. Flange Gaskets are available for wide flange configurations.
- Plumbing Industry: Here, the standard ring and full face flange gaskets are available in various styles.
- Sheet Metal Enclosures: The flange gaskets used here are normally rectangular in shape. They come with adhesive on one side which is used as a gasket to seal out dust, liquids or air.
- Electronic, food, medical, chemical and packaging industries: The flange gaskets used here have a flat surface that is compressed between two flanges.
