Blue wind power silicone hose with 4-layer fabric and steel wire reinforcement installed in turbine nacelles for gearbox coolant transfer.

Background

The customer required high-purity silicone tubing that could withstand repeated CIP/SIP cycles while maintaining low extractable levels for critical pharmaceutical processing. Their existing tubing showed inconsistent batch-to-batch performance and occasional extractable failures.

Challenge

The key challenges included:

• Maintaining ultra-low extractables across production batches
• Withstanding repeated SIP cycles at 121 °C without degradation
• Ensuring consistent dimensional tolerances for automated filling equipment
• Meeting USP Class VI and ISO 10993 biocompatibility requirements

Solution

Rekky supplied platinum-cured silicone tubing with documented batch-to-batch consistency. Each production batch was tested for extractables, dimensions and visual quality, with full COA documentation provided.

Results

After switching to Rekky tubing, the customer reported:

Conclusion

The switch to Rekky platinum-cured silicone tubing delivered measurable improvements in purity, consistency and operational efficiency. Full compliance documentation and batch traceability gave the customer confidence in their regulatory filings.
