How to Select the Right Sealing Material for Industrial Applications

Understanding Material Performance Before Choosing a Sealing Product

The performance of a sealing product depends not only on its design but also on the material used. Different operating environments require different material characteristics to ensure reliable sealing performance and longer service life.

Coraseals helps customers evaluate suitable sealing materials according to application conditions, equipment requirements, and operating environments.

Key Factors When Selecting Sealing Materials

Before choosing a sealing material, several factors should be considered:

Temperature Resistance

Industrial equipment may operate under high or low temperature conditions. The selected material should maintain stable performance within the required temperature range.

Chemical Compatibility

Different fluids may react differently with sealing materials. Material compatibility is important when equipment operates with oils, chemicals, water, steam, or other media.

Pressure and Mechanical Conditions

Pressure levels, movement, compression, and installation conditions can influence sealing performance.

Common Industrial Sealing Materials

NBR (Nitrile Rubber)

NBR is commonly used where oil resistance and general mechanical performance are required.

Typical applications:

• Oil systems

• Industrial equipment

• General sealing applications

EPDM (Ethylene Propylene Rubber)

EPDM provides good resistance to water, steam, and weather conditions.

Typical applications:

• Water systems

• HVAC equipment

• Heat exchanger applications

FKM (Fluoro Rubber)

FKM is selected for applications requiring higher temperature resistance and chemical durability.

Typical applications:

• Chemical environments

• High-temperature equipment

• Special industrial applications

PTFE

PTFE provides excellent chemical resistance and is suitable for demanding environments.

Typical applications:

• Chemical processing

• Special industrial sealing applications

Selecting the Right Solution

There is no single sealing material suitable for every application.

Coraseals works with customers to evaluate:

• Equipment conditions

• Operating environment

• Required service performance

• Material compatibility

By selecting the right material and product design, customers can improve sealing reliability and reduce maintenance issues.
