O-Ring Types
Precision Polymer Engineering (PPE) operates and manufactures O-Rings in clean room facilities from United Kingdom or United States. The O-Rings are produced in clean room environment of Class 1000 or Class 10,000 standard.
Factors such as chemicals or gases exposure will affect the integrity of the O-Rings. Therefore, choosing the correct material for O-Rings is important to maximise the expected lifetime.
In order to ensure the best fit, our technical and sales team will first understand your requirements to recommend the most suitable type(s) of O-Ring for your applications.
We will require some information such as:
- Temperature (Minimum / Maximum)
- Length of time exposed to temperature
- Chemicals used in the application
- Type of Seal
- Pressure on the seal
- Application used for semiconductor process
Based on inputs gathered from customers, our technical and sales team will be able to recommend the best material O-Rings suited for our customers’ requirement.
There are different types of O-Ring for various applications across different industries:
