FDA Silicone O Ring – Complete Product Guide

FDA silicone O-rings are essential sealing components designed for industries where hygiene, chemical purity, and reliable performance are mandatory. Whether used in food production, beverage machinery, medical devices, or pharmaceutical equipment, these O-rings deliver safe and long-lasting sealing under demanding conditions.

What Makes FDA Silicone Different?

FDA-compliant silicone is made from medical-grade or food-grade raw materials. It contains no toxic additives, odors, or contaminants-making it safe for direct contact with food, liquids, and pharmaceuticals.

Why FDA Certification Matters

FDA 21 CFR 177.2600 certification ensures the silicone material is safe for:

• Food and beverage processing
• Medical and healthcare applications
• Pharmaceutical production

This certification is essential for companies entering the U.S. market or supplying international brands.

What Silicone Is Made Of

Silicone rubber is a highly active adsorption material with the chemical formula:

mSiO₂ · nH₂O

This structure allows silicone to withstand extreme temperatures, resist aging, and maintain excellent elasticity.

Global Compliance Certifications

Our FDA silicone O-rings meet multiple international safety standards:

• FDA 21 CFR 177.2600
• USP Class VI
• LFGB (Germany)
• EC 1935/2004 (EU Food Contact)
• RoHS & REACH Safe

Free from BPA, phthalates, latex, and animal-derived ingredients

This ensures safe and compliant use in global markets including the U.S., EU, and Asia.

Temperature Resistance

• Performs from -60°C to 230°C
• Short-term heat resistance up to 446°F (230°C)
• Suitable for hot beverages, sterilization, and steam environments

Compression Set Performance

• Silicone maintains a 30–50% compression set, meaning it stays elastic and seals tightly even after long-term pressure.

Chemical Compatibility

Resistant to:

• Water & steam
• Mild acids and alkalis
• Food oils & beverages
• Cleaning agents
