There aren’t many options in finding a seal that is resistant to acids, caustics and sensitive media, performing at low and high temperatures and pressures. De GYLON® BIO-PRO PLUS™ guaranteed meets all of these criteria. Not only providing safe and efficient processes but also optimizing stock keeping.

Fulfilling ASME-BPE standards for dimensional consistency, this next generation sanitary gasket ensures ease of installation and long term operational integrity in the most challenging and critical applications. GYLON® BIO-PRO PLUS™ is pre-formed and stress controlled with high manufacturing precision, helping to eliminate critical and costly contamination issues often associated with gasket recession or intrusion within hygienic couplings.


  • Safe solution for all tri-clamp
  • Dimensionally stable
  • Resistant to intrusion into the pipe bore
  • Best suited for CIP/SIP applications
