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

Selecting the optimum sanitary gaskets, sanitary seals and O-Rings for specific 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 gaskets and seals have 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 its mean time between failure, (MTBF) thereby preventing costly unscheduled down time. Dangerous leakage and product contamination can also be eliminated by the selection of the optimum tri-clamp or sanitary gasket for the application.

At the heart of any sealing device is the material from which it has been fabricated. In addition to offering a broad range of high quality standard materials, 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 of aggressive pharmaceutical, biotechnology and food and beverage production processes. These are:

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

Each of these materials has its own unique properties that allow them to provide long life and excellent service where EPDM, FKM , PTFE, BUNA and silicone sanitary gaskets or O-Rings fail. They perform in the most challenging SIP, (steam in place) CIP (clean in place) and WFI (water for injection) sterilization processes.
