Gasket materials are designed to compress under load to achieve the initial seal. However, to retain that seal, the gasket should be able to resist flow (or creep) to prevent loss of surface stress by bolt reduction. This property is very important and is the one that most readily separates high quality from low quality gaskets.

Some factors need to be considered in selection of the correct gasket material and type i.e.:

1) Vibration

If the pipeline is subjected to undue vibration, then the gasket has to withstand the mechanical effects involved.

2) Erosive Media

Certain media (e.g. solids suspended in liquids) can slowly erode gaskets leading to a much shorter life than expected. In such cases, choice of gasket material and selection of gasket dimensions are critical. 

Flange gasket can be made according to client drawing from rubber material such as EPDM, NR, NBR, SBR, SILICONE, etc depends on flange gasket usage.

These flange gaskets are fixed between two sections of pipe which are flared, thereby offering a higher surface area. All flange gasket can be customized to fit client requirement.
