In oilfields in the Middle East or industrial engines in Africa, temperature resilience directly impacts equipment uptime.

3. Chemical Compatibility
One of Viton’s main advantages is its outstanding resistance to fuels, oils, most acids, and hydrocarbons. However, standard Viton is not suitable for all chemicals (e.g., ketones, amines, some esters). Always cross-check the specific formulation’s resistance against the chemicals present in your process. Failure to match O-ring type and compatibility can result in early failure and costly downtime.

4. Hardness (Shore A)
The hardness of an O-ring—measured on the Shore A scale—affects sealing efficiency and friction. Most Viton O-rings are produced in 75 Shore A, but variants exist. A proper match prevents leaks while allowing flexibility for installation and assembly. Specify hardness values in your RFQ, particularly for dynamic or high-pressure applications.

5. Dimensional Tolerance and Sizing
Accurate dimensions (ID, OD, cross-section) and tolerance levels are indispensable to ensure a secure and leak-free seal, especially when dealing with metric and non-standard sizes common in international projects. For critical assemblies, confirm adherence to standards such as AS568 (USA) or ISO 3601 (metric), and request tolerance data from your supplier.

6. Compression Set Resistance
This property indicates the O-ring’s ability to recover its original thickness after being compressed. High compression set resistance is preferred to maintain sealing integrity over repeated cycles or prolonged use, crucial for minimizing maintenance in remote operations.
