The Sanitary Seal Division of PTI specializes in the development and manufacture of FDA and USP compliant sanitary gaskets and sanitary seals for the biotechnical, pharmaceutical and food and beverage industries. Our proprietary materials have been developed to operate in the most stringent tri-clamp applications and environments.

Selecting the optimum sanitary gaskets and sanitary seals for specific tri-clamp applications requires the understanding of the expected process environment, the cleaning and sterilization processes employed and the physical properties and chemical resistance of the material from which the sanitary gasket has been fabricated.

In general, the guiding principle in sanitary gasket selection should be "value in use". Sanitary gaskets constructed of standard materials may suffice in a given production process but fail when exposed to higher temperature steam or caustic cleaning fluids. Typically, the higher cost of a high performance sanitary gasket can be recouped many times over by its long service life. Selecting the proper high performance sanitary gasket can increase the mean time between failure, (MTBF) thereby preventing costly unscheduled down time. Tri-clamp leakage can be dangerous and can also cause product contamination. Most leakage problems can be eliminated by the selection of the optimum sanitary gasket for the application.

At the heart of a sanitary gasket is the material from which it has been fabricated. In addition to its standard material offerings, the Sanitary Seal Division of PTI offers three high performance materials that have the mechanical properties and chemical/caustic/steam resistance to provide superior service in a wide rage aggressive pharmaceutical, biotechnology and food and beverage production processes.

Sanifluor® 1000 — (Aflas®  Formulation)
Tyfluor™ — (Modified PTFE)
Viton® Extreme

Sanifluor 1000, Tyfluor and Viton Extreme each has superior properties that allow them to provide long life and excellent service where EPDM, FKM, PTFE and silicone products fail. They perform in the most challenging SIP, (steam in place) CIP (clean in place)and WFI (water for injection) sterilization  processes.
