Types of Plastic Gaskets
Plastic gaskets been available in numerous kinds, each serving specific requirements. Here are some of the most common types:
1. Flat Gaskets
Flat gaskets are basic, circular or rectangular sealing components that fit between two mating surface areas. These gaskets are frequently used in applications like valve covers, flanges, and piping connections.
2. O-Rings
O-rings are circular gaskets created to fit snugly into a groove, developing a safe and secure seal. They are commonly utilized in hydraulic and pneumatic systems due to their trustworthy sealing capability.
3. Spiral Wound Gaskets
These gaskets include rotating layers of metal and filler material. They are created for high-pressure and high-temperature applications, making them appropriate for oil and gas industries.
4. Customized Gaskets
Custom-made gaskets are customized to specific applications, created to satisfy distinct dimensional, material, and efficiency requirements.
