Quality & Certifications
ISO 9001 certified manufacturing with full material traceability, RoHS, REACH and FDA compliant compounds.
Our Commitment to Quality
Every O-ring we ship is backed by a quality system built for industrial buyers who need documentation, repeatability, and compliance. Our factory operates under ISO 9001:2015, and our materials are validated for RoHS, REACH, and FDA food-contact requirements. For pharmaceutical and medical customers, we also supply USP Class VI certificates and lot-specific test reports.
Certifications & Compliance
ISO 9001:2015
Our quality management system covers incoming material inspection, in-process monitoring, dimensional verification, and outgoing batch release.
RoHS Compliant
All standard compounds are restricted-substance compliant per EU RoHS directives, suitable for electrical and electronic equipment markets.
REACH Compliant
Full SVHC disclosure and REACH registration documentation available on request for European import requirements.
FDA 21 CFR 177.2600
Food-grade EPDM, VMQ (Silicone), and PTFE compounds meet FDA requirements for repeated food-contact applications.
USP Class VI
Pharmaceutical-grade Silicone and EPDM are available with USP Class VI biocompatibility certification.
NSF 61 / WRAS
Potable water grades available for EPDM O-rings used in drinking water, beverage, and plumbing systems.
Testing & Inspection Capabilities
Hardness Testing (Shore A / D)
Every batch is checked for hardness to confirm compound consistency and specification compliance.
Dimensional Inspection
Inside diameter and cross-section are measured with calibrated instruments against AS568 or ISO 3601 tolerances.
Visual & Defect Screening
100% visual inspection for flash, voids, cracks, contamination, and surface defects before packing.
Material Certificates
Standard supply includes a material test certificate. Lot-specific reports and third-party test data available on request.
Batch Traceability
We maintain batch-level traceability from raw compound through molding, trimming, and inspection. If a quality issue arises, we can trace the affected lot back to the cure press, operator shift, and material batch within hours.
Frequently Asked Questions
Can you provide a certificate of conformity with my order?
Yes. A material test certificate (MTC) and dimensional inspection report are provided as standard. For regulated industries, we can also supply REACH/RoHS declarations, FDA compliance letters, and USP Class VI documentation.
Do you offer USP Class VI silicone O-rings?
Yes. We supply USP Class VI certified VMQ (Silicone) and EPDM grades for pharmaceutical and medical device applications. Certificates are batch-specific.
Is your FDA grade suitable for drinking water?
FDA 21 CFR 177.2600 covers food contact. For direct drinking water contact, we recommend NSF 61 or WRAS certified EPDM grades, which we also supply.
How do I request lot traceability documentation?
Mention the requirement in your purchase order or quote request. We will include the lot number, cure date, compound batch reference, and operator shift record with your shipment.
