Specify media exposure in detail when requesting quotes, to prevent sealing failures due to material incompatibility—this is especially critical for industries like water treatment or chemical processing.

4. Hardness (Durometer, Shore A):
   Executed in Shore A units (commonly 60-80), hardness defines elasticity and compression. Softer compounds (lower Shore A) seal more easily in low-pressure environments; harder grades handle higher pressures without extruding. Clarifying hardness requirements reduces installation failures and maintenance costs.

5. Dimensional Tolerances:
   O-ring performance relies on precise sizing—tight tolerances dictate effective sealing and long service life. Request clear information about cross-sectional and inner diameter tolerances (e.g., ISO 3601 or AS568 standards). This is critical for OEM, aftermarket, and cross-border machine compatibility.

6. Certifications & Compliance:
   Many markets require third-party approved materials. Common certifications include FDA (food contact), NSF (drinking water), KTW/WRAS (Europe, potable water), or REACH/RoHS (EU chemical safety). Seek documented evidence from suppliers, especially when exporting to the EU or managing regional regulatory scrutiny.
