If you are looking for a sealing material resistant to acids, caustics and sensitive media, performing at low and high temperatures and pressures, options are difficult to find. The available elastomers generally fail in at least one of these requirements and conventional PTFE is not suitable due to its cold flow properties. The restructured and modified PTFE of the GYLON BIO-LINE® is guaranteed to meet all these criteria. Not only providing safe and efficient processes but also optimizing stock keeping.

GYLON BIO-LINE® also resolves a further problem of the elastomeric seals. Elastomeric seals extrude from connections due to mechanical stresses from vibrations and misalignment. Extruded elastomeric seals create dead spaces that impair the cleaning and sterilization. The contamination of subsequent charges through residues on the sealing material could be a consequenze. GYLON BIO-LINE® seals remain flexible, tight and flush with the pipe bore even under high loads.

GYLON BIO-PRO® seals offer a safe solution with its modified and restructured PTFE material, pre-formed and stress controlled, for all TRI-CLAMP standards. It is dimensionally stable and resists intrusion into the pipe bore. Can be safely used with all cleaning, neutralizing and sterilizing media, including steam, and for all standard process temperatures.
