Sealing is vital to the safety and efficiency of mechanical systems.GasketIt is a small but effective piece at the center of this work. Gaskets produced in different forms and materials depending on the application area prevent the passage of liquid, gas or dust.
In this article;What is a gasket?, WhichThere are types, Whichproduced from materialsAndWhere is it used?, we explain in detail.
What is a Gasket?
The gasket is a gasket placed between two surfaces andsealingIt is an elastic or rigid element. It generally prevents the passage of liquid, gas or particles by filling the microscopic gaps at the connection points.
What are the Gasket Types?
gasketstheir shapes, materials and functionsWe can classify it according to:
1. Shape and Application Based Types
- Flat gasket:It is used in flange connections.
- O-ring seal:Round cross-section, ideal for dynamic and static sealing.
- Spiral wound gasket:It is used in high pressure and temperature applications.
- Labyrinth seal:It generally provides sealing on rotating parts without contact.
- Felt gasket:Used for dust sealing and light liquid barrier.
2. Material Based Types
| Material | Features | Areas of Use |
| Plastic (PTFE, PE, PVC) | High chemical resistance, flexible | Food, medical, chemistry |
| Metal (Aluminum, Stainless Steel) | Resistant to high temperature and pressure | Automotive, power plants |
| Rubber (EPDM, NBR, Viton) | Flexible, vibration dampening | Automotive, pump systems |
| Felt | Dust catcher, oil absorber | Engine parts, electric motors |
| Silicon | High temperature resistant, food compatible | Oven systems, healthcare industry |

Things to Consider When Selection of Gaskets
Choosing the right gasket affects both the performance and safety of the system. When choosing:
- Temperature and pressure rangesuitability
- chemical resistance(acid, oil, solvent etc.)
- Surface roughness and contact area
- Mounting method(screwed, clamped, welded)
- Durability and maintenance frequency
should be evaluated.

Frequently Asked Questions
What does the gasket do?
The gasket prevents the passage of liquid, gas or dust by providing a seal between two surfaces.
What is the most commonly used gasket type?
O-ring and flat seals are the most commonly used. The type varies depending on the application location.
How long is the gasket life?
It depends on the terms of use; Pressure, temperature and chemical interactions affect lifespan.
What is the difference between a plastic gasket and a metal gasket?
While plastic gaskets offer flexibility and chemical resistance, metal gaskets are resistant to high pressure and temperature.
Is it possible to produce special size gaskets?
Yes, special production is possible according to technical drawing and sample.
