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-LINE® guaranteed meets all of these criteria. Not only providing safe and efficient processes but also optimizing stock keeping. This seal can be safely used with all cleaning, neutralizing and sterilizing media, including steam, and for all standard process temperatures.

Next to this, this seal solves another problem. The GYLON BIO-LINE® seals remain flexible, tight and flush with the pipe bore even under high loads. It wont harm the cleaning an sterilization since there won’t be any dead spaces. Other Elastomeric seals extrude from connections due to mechanical stresses from vibrations and misalignment, causing the existence of dead spaces.


  • Safe solution for all tri-clamp standards
  • Dimensionally stable
  • Resistant to intrusion into the pipe bore
