Kinds Of Plastic Gaskets
Plastic gaskets been available in various kinds, each serving specific requirements. Here are a few of the most typical types:
1. Flat Gaskets
Flat gaskets are basic, circular or rectangular sealing components that fit in between two mating surfaces. These gaskets are often used in applications like valve covers, flanges, and piping connections.
2. O-Rings
O-rings are circular gaskets created to fit comfortably into a groove, producing a protected seal. They are widely used in hydraulic and pneumatic systems due to their reputable 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 suitable for oil and gas markets.
4. Customized Gaskets
Customized gaskets are customized to specific applications, created to fulfill unique dimensional, material, and performance requirements.
Table 2: Types of Plastic Gaskets and Their Uses
| Type | Description | Normal Uses |
|---|---|---|
| Flat Gaskets | Easy shapes with even surfaces | Flanges, valve covers |
| O-Rings | Circular gaskets fitting into grooves | Hydraulic systems, pumps |
| Spiral Wound Gaskets | Layered gaskets for high pressure/temperature | Oil and gas, chemical processing |
| Customized Gaskets | Customized gaskets for specific applications | Various industrial applications |
