When it comes to filter housings, most models come equipped with Viton O-rings as the standard seal. However, there are numerous other sealing options that can be specified to meet specific application needs. These filter housings can be delivered with the desired seals pre-installed, offering versatility for various industries.
While Viton and Nitrile O-Rings are widely used due to their reliability in many environments, certain applications demand more specialized sealing solutions. In such cases, filter housings can be sourced from stock with alternative options like Kalrez and Chemraz compounds. These materials provide enhanced durability and performance in extreme conditions.
For instance, Kalrez seals, made from perfluoroelastomers, are renowned for their exceptional resistance to chemicals and high temperatures, making them ideal for demanding industrial settings. Similarly, Chemraz seals offer comparable benefits and are often preferred for their superior chemical compatibility.
Other popular sealing options include EPDM and silicone seals, which are valued for their flexibility and broad temperature ranges. EPDM seals, derived from ethylene-propylene materials, are particularly effective in applications requiring resistance to ozone, steam, and extreme weather conditions. Silicone seals, on the other hand, are known for their excellent thermal stability and ability to function well in both low and high-temperature environments.
Below is a detailed table summarizing the types of seals available, along with their respective temperature ranges:
| **Name** | **Type** | **Temperature Range** |
|----------------|-------------------------|------------------------------|
| Viton | Fluorocarbon | -30°C to +200°C |
| Kalrez | Perfluorelastomer | -50°C to +316°C |
| Chemraz | Perfluorelastomer | -50°C to +324°C |
| EPDM | Ethylene-Propylene | -55°C to +150°C |
| PTFE | Solid PTFE | -260°C to +200°C |
| FEP Encapsulated PTFE | FEP Encapsulated PTFE | -60°C to +200°C |
| Silicone | Silicone | -60°C to +230°C |
| Nitrile | Buna N-Nitrile | -35°C to +110°C |
| Neoprene | Chloroprene-Neoprene | -45°C to +100°C |
