A gasket is a seal between two surfaces to prevent loss of containment. Different types of gaskets include; Rubber, reinforced rubber, compressed non asbestos fibre jointing (CNAF), Chemical resistant material such as PTFE, metallic and semi metallic (graphite laminates) gaskets for high pressure and temperature applications. This includes steam, hydrocarbons and chemical processing.
This is dependent on the application. The gasket must be compatible with the operating parameters. This includes; the medium, pressure and temperature requirements.

The cost of a quality gasket is relatively low compared to the expense of downtime and corrective action experienced when a failure occurs. This can include danger to personnel, equipment and the environment. Not to mention labour costs associated with the repair and lost opportunity. Cheap imported products are not necessarily manufactured to the standards required in many industrial applications.

Never re-use gaskets as once they have been compressed a second time, they will not have the recovery properties required to seal in the majority of applications.

It is not recommended to use a sealant with a gasket. Many sealants contain chemicals that are not compatible with gasket materials, this causes them to fail prematurely. The principle of effecting a seal is by creating sufficient friction between the gasket material and flange to prevent the medium passing between the flange and the gasket. Known as a loss of containment.

If the correct gasket material has been selected, the failure is normally due to installation error. Other things that effect failure (loss of containment) are:

  • The age of the gasket material
  • How the gasket has been stored (flat, out of sunlight and ozone)
  • Gaskets must be dry when installed
  • Correct bolting must be used (grade, cleanliness, lubricated)
  • Tightened up in sequence to the correct torque in at least three stages (30%, 60%, 100%)
  • Flanges need to be parallel and not reliant on the bolts to pull flanges together
  • Excursions from normal operating parameters. This means exceeding the capabilities of gasket material and joint design. Example: Thermal and pressure cycling
PTFE tape, commonly known as plumber’s tape, is used to seal threaded joints less than 260 degrees Celsius. Commonly used on water and gas installations. In gas applications it must be AGA approved and is normally yellow.
If applied correctly on threaded joints, it will seal under normal operating conditions less than 260 degrees Celsius. Commonly used on water and gas installations. In gas applications it must be AGA approved and is normally yellow.
