Project Spotlight

Pharmaceutical facility connector installation
Pharmaceutical Manufacturing

Cleanroom Connector Upgrade for a GMP Facility in New Jersey

A mid-size pharmaceutical company operating a 40,000 sq ft GMP cleanroom needed to replace aging M12 sensor connectors that were failing IP washdown requirements during quarterly validation audits. The existing connectors showed seal degradation after 18 months of daily CIP (Clean-in-Place) cycles using 80°C caustic solution.

Our application engineering team specified IP69K-rated stainless steel circular connectors with EPDM seals designed for repeated chemical exposure up to 100°C. The installation covered 120 connection points across three production lines. After 14 months in service, all connectors passed validation with zero seal failures — compared to a 12% failure rate with the previous supplier's product.
