Food-Grade High-Precision Sealing Rings | Dedicated Seals for Quick-Connect Fittings with DIN/3A/ISO Certifications | Compatible with Viton®, Silicone, EPDM, and PTFE Materials
Tailored for fluid systems in food, pharmaceutical, and bioprocess industries, ourfood-grade sealing ringsserve as the core sealing solution for quick-connect fittings (DIN 11851, DIN 11850) and union joints (DIN 32676). They strictly comply with3A Sanitary Standards,ISO 9001 Quality Management Systems, andSMS Installation Specifications, ensuring zero-leakage, contamination-free transfers in dairy, beverage, pharmaceutical, and cosmetic applications.
Core Advantages
✅Full Material Spectrum Coverage:
• Chemical-Resistant Type: Viton® (FKM) withstands strong acids, solvents, and high temperatures (-20°C to 200°C), ideal for CIP/SIP cleaning environments.
• High-Elasticity Food-Grade Type: Silicone (FDA 21 CFR 177.2600 certified) resists low temperatures (-60°C to 230°C), used in dairy and juice pipelines.
• Cost-Effective Durable Type: EPDM resists ozone aging, suitable for pure water and steam systems (-50°C to 150°C).
• Ultra-Low Adsorption Type: PTFE/Teflon™ meets USP Class VI biocompatibility requirements, used for high-purity pharmaceuticals or cell culture media sealing.
• Precise Dimensional Tolerances(±0.1mm): Perfectly fits mainstream quick-connect systems like Swagelok and Tri-Clamp, reducing installation torque deviations.
• Compression Set Resistance: Passed 10,000 dynamic pressure tests, extending seal life by 300% and reducing downtime costs.
• Multi-Condition Adaptability: Supports extreme temperatures (-100°C to 260°C), vacuum to 10 bar pressure scenarios, and steam sterilization (SIP) with acid/alkaline cleaning agents.
Typical Applications
• Food & Beverage: Quick-connect fittings for dairy filling lines, union seals for beer fermentation tanks.
1. Tech-Jargon Precision: Retained industry-specific terms (e.g., “Swagelok,” “SIP”) to maintain technical accuracy while ensuring clarity for global audiences.
2. Compliance Hierarchy: Structured certifications by regional authority (EU/US) and industry standard (3A/ISO) to reinforce credibility.
3. Material Trademarks: Used registered trademarks (e.g., Viton®, Teflon™) where applicable to align with legal requirements.
4. Performance Metrics: Translated technical specs (e.g., -100°C to 260°C, Ra≤0.8μm) directly to ensure no data loss.
