The pharmaceutical industry has strict requirements for O-ring materials, mainly to ensure the safety, purity and performance of the product, in compliance with pharmaceutical production and regulatory standards. The following are key requirements and considerations:

1. Biocompatibility of O-ring materials

• O-rings must be made of biocompatible materials and will not react harmfully with substances in contact with drugs or equipment.


• Usually need to meet the biocompatibility test standards of ISO 10993 or USP Class VI.

2. Chemical inertness

• The material must have high chemical stability and cannot react with drugs, cleaning agents or sterilizing agents.


• Highly inert materials such as fluororubber (FKM), perfluororubber (FFKM), VMQ o-ring are usually selected.

3. High temperature and chemical resistance

• Pharmaceutical processes often involve high temperature sterilization (such as steam sterilization) and strong acid and alkali cleaning processes, and O-rings need to maintain performance under extreme conditions.


• The material must withstand CIP (cleaning in place) and SIP (sterilization in place) processes.

4. Low precipitation and no contamination

• O-ring materials must not release contaminants or soluble substances to avoid contaminating drugs.


• Must pass FDA food grade certification to ensure that the material is non-toxic and can be used in drug production.

5. Mechanical properties

• O-rings must have good elasticity and wear resistance to maintain performance for a long time in a sealed state.


• The material needs to have low compression set to extend service life.

6. Antimicrobial properties

• Some pharmaceutical environments may require antimicrobial properties to prevent microbial contamination.

7. Compliance with pharmaceutical standards

• Must meet multiple industry and international certifications, such as:

• FDA CFR 21.177.2600 (food contact materials)

• USP Class VI (biocompatibility)

• EU 1935/2004 (European food contact material regulation)

• 3-A sanitary standards (commonly used in the dairy and food industries)

• ISO 13485 (quality management system for medical devices)

8. Traceability and verifiability

• In the pharmaceutical industry, product traceability is critical. O-ring suppliers are required to provide detailed material batch reports and compliance certificates to ensure that the source of all materials is clearly traceable.
