What are sealing gaskets?
Sealing gaskets are commonly used in engineering and industrial applications to prevent leaks of liquids or gases in mechanical connections. They are circular or square rings, usually made of elastomeric materials such as rubber, silicone, NBR, Viton, or neoprene, which are placed in grooves, housings, or channels specifically designed for them.
These sealing gaskets work by compressing when two mechanical parts are assembled, creating a watertight seal between them. Due to their simple and effective design, they are widely used in a variety of applications, from industrial machinery to hydraulic and pneumatic systems.
Sealing gaskets are known for their ability to seal efficiently even under high pressure and temperature conditions due to the diversity of materials in which they can be manufactured.
What types of sealing gaskets exist?
There are different types depending on the application:
- O-rings
- Flat joints
- Rubber gaskets (NBR, EPDM, FKM)
- Metal gaskets
- High-temperature gaskets
- Gaskets for hydraulic and pneumatic systems
What materials are used in sealing gaskets?
The most common materials are:
- NBR (nitrile): general use in hydraulics and pneumatics
- EPDM: water and steam resistant
- FKM (Viton): high chemical and thermal resistance
- Silicone: food and healthcare applications
- PTFE: high chemical resistance and low friction
What should be taken into account when choosing a sealing gasket?
Several factors must be taken into account:
- Type of fluid (air, water, oil, chemicals)
- Operating temperature
- System pressure
- Chemical compatibility of the material
- Dimensions and type of accommodation
What is the difference between an O-ring and a flat gasket?
The O-ring is circular in shape and is used in specific housings, while the flat gasket is used on larger contact surfaces for static sealing.
Can custom gaskets be manufactured?
Yes, in many cases it is possible to manufacture custom gaskets according to specific dimensions, material and working conditions.
