Quality & Certifications

Quality management is a critical factor in the reliability and performance of O-Rings and sealing products. Our quality system focuses on process control, material consistency, and dimensional verification to support industrial, OEM, and long-term supply applications.

This page outlines our quality approach, inspection procedures, and compliance capabilities to help engineers and procurement teams evaluate suitability for their projects.

Quality Management Approach

Our quality management approach is built around standardized procedures, documented processes, and continuous monitoring throughout manufacturing. The goal is to ensure repeatability, traceability, and stable performance across production batches.

  • Process-oriented quality control
  • Defined inspection checkpoints
  • Material and batch traceability
  • Preventive quality planning

Incoming Material Control

Raw materials and compounds are verified before production to ensure they meet specified requirements for hardness, appearance, and processing suitability.

  • Material identification and verification
  • Hardness spot checks
  • Visual inspection for contamination or defects
  • Batch labeling and record keeping

In-Process Quality Control

Quality checks are integrated into the manufacturing process to detect variation early and maintain dimensional consistency.

  • Dimensional sampling during production
  • Process parameter monitoring
  • Visual inspection after molding and finishing
  • Control of post-curing conditions

Final Inspection & Verification

Before shipment, finished O-Rings undergo final inspection based on order requirements and applicable standards.

Inspection Item Typical Method
Dimensions (ID / CS) Sampling measurement
Hardness Shore A testing
Appearance 100% or sampling visual check
Packaging & labeling Order verification

Standards & Compliance

We manufacture O-Rings in accordance with commonly used international dimensional standards. Compliance is based on customer requirements and applicable drawings or specifications.

  • AS568 O-Ring dimensional standard
  • ISO 3601 O-Ring sizes and tolerances
  • DIN 3771 legacy metric systems
  • Customer-specific specifications

Certifications & Documentation Support

Depending on project requirements, supporting documentation can be provided to assist with quality review and supplier approval processes.

  • Material data sheets (on request)
  • Inspection records and reports
  • Batch identification and traceability information
  • Declaration of conformity (where applicable)

Please note that documentation availability depends on material type, order volume, and project scope.

Quality for OEM & Long-Term Supply

For OEM and repeat production programs, quality consistency and change control are critical. We support long-term supply by maintaining stable processes and communicating any necessary changes in advance.

  • Consistent compound and process control
  • Repeatability across production batches
  • Support for customer audits (by arrangement)
  • Long-term cooperation focus

Why Quality Matters in Sealing Applications

O-Ring performance is highly sensitive to dimensional variation, material consistency, and surface condition. A controlled quality process reduces leakage risk, downtime, and total cost of ownership in industrial systems.
