Gaskets are used to provide sealing in different systems. HoweverNot every gasket works in every environment. Many technical criteria such as temperature value, pressure level, chemical structure and installation method of the application necessitate the selection of the correct gasket.
In this guide, especiallyHow to choose gaskets used in industrial applications, it explains step by step what to pay attention to.
Basic Criteria to Consider When Selection of Gaskets
1. Operating Temperature
The temperature range of the environment where the gasket will be placed must be known. Each material has a different heat resistance:
| Material Type | Strength Range |
| EPDM | -40°C / +130°C |
| NBR (nitrile) | -20°C / +100°C |
| PTFE | -200°C / +260°C |
| metal gasket | up to +500°C |
Incorrect temperature selectionThis causes problems such as gasket deformation, hardening or cracking.
2. Pressure Value (Bar/Psi)
For the seal to be successful, the gasket must be suitable for the application.mechanical strengthIt should show.
- Low pressure: soft elastomer seals (e.g. silicone)
- High pressure: metal-reinforced spiral seals, PTFE-reinforced seal systems
A gasket that is not suitable for pressure prevents the system from operating completely leak-free.
3. Environment (Chemical Compatibility)
The gasket is located in the environmentoil, fuel, acid, steam, solventIt should not react chemically with substances such as.
| Chemical | Suitable Gasket Material |
| oil, fuel | NBR, Viton |
| acid, base | PTFE, EPDM |
| Steam | Metal gasket with graphite |
| This | EPDM, silicone |
4. Seal Thickness and Channel Structure
- The gasket thickness must fit snugly to the contact surface and not cause deformation when over-compressed.
- There must be optimum space between the channel width and the gasket diameter.
To determine these measurementstechnical drawing or application sampleIt is recommended to make an evaluation based on
5. Mounting and Surface Conditions
- Flange surfaces are smooth and cleanshould be.
- bolt torqueIt should be sufficient to compress the gasket but at a level that does not cause damage.
- In O-ring systems, surface smoothness is especially important.
Gasket Material Selection Table
| Application Area | Suitable Material | Explanation |
| Food & Medical | Silicone, PTFE | Odor-proof, hygienic |
| Automotive | NBR, Viton | High fuel and oil resistance |
| chemical systems | PTFE, EPDM | High chemical resistance |
| high temperature | Metal, graphite gasket | Resistant to extreme heat |
| Outdoor & UV | EPDM, TPE | Resistant to sun and ozone |
Risks of Choosing the Wrong Gasket
- Leakage and system efficiency loss
- Wear, cracking, gasket rupture
- Explosion of the gasket due to improper compression
- High maintenance costs and downtimes
Therefore, the correct use of gaskets for each projectlong term performanceprovides.
