Types of Plastic Gaskets

Plastic gaskets come in various kinds, each serving specific requirements. Here are a few of the most common types:

1. Flat Gaskets

Flat gaskets are simple, circular or rectangle-shaped sealing elements that fit in between two mating surface areas. These gaskets are often utilized in applications like valve covers, flanges, and piping connections.

2. O-Rings

O-rings are circular gaskets designed to fit comfortably into a groove, creating a secure seal. They are widely utilized in hydraulic and pneumatic systems due to their reputable sealing capability.

3. Spiral Wound Gaskets

These gaskets include alternating layers of metal and filler material. They are developed for high-pressure and high-temperature applications, making them suitable for oil and gas markets.

4. Custom-made Gaskets

Custom-made gaskets are tailored to specific applications, created to satisfy special dimensional, product, and performance requirements.
