GYLON BIO-LINE® Aseptic Food Grade PTFE Gaskets

Process and equipment reliability

GYLON BIO-LINE® PTFE material provides exceptional sealing performance for all pharmaceutical and food processing applications and processes. It’s restructured PTFE composition provides safe, durable and consistent sealing performance in a range of challenging environments, including exposure to acids, caustics, sensitive media, low and high temperatures and pressures.

By remaining flexible, tight and flush with the pipe bore, even under high loads, GYLON BIO-LINE® gaskets further eliminate the potential for process material contamination caused by traditional elastomeric seals.
