Hygienic Gaskets

The Rubber Fab Smart Gaskets value is proven when validating in high - purity pharmaceutical system.

A standard sanitary flange utilizing the Smart Gasket, Thermocouple Gasket obtains the critical thermal mapping information needed during the validation process.

Meter fluids in your process system using a peristaltic pump or withdraw samples through valve or syringe.

Then, utilize Rubber Fab's Spore Trap Gasket to securely retain spore test strips. These gaskets can be supplied in KFM (Viton) and Silicon.

PTFE is the material of choice whenever low temperature flexibility or gasket memory is not required and can remain in service for longer periods of time in both water and steam applications. PTFE is   not recommended with large temperature variations due to creep and cold flow. PTFE has minimal extractables, has a low absorption rate and excellent resistance to process fluids.

Platinum Cured Silicone is the material of choice in sanitary water systems when PTFE is not feasible due to severely misaligned fittings, or if the cost of high pressure clamps does not outweigh the benefits of PTFE (extended service life). See Rubber Fab’s Platinum Silicone Hygienic Seal literature for more information.

FKM Fluoroelastomer and EPDM compounds are specified by many of our process equipment manufacturers. They are generally suitable for these applications, however, service life must be considered and a preventative maintenance program be implemented to mitigate degradation.

Buna is the last choice in most applications due to temperature limitations and does not pass U.S. Pharmacopeia Class VI Certification and Cytotoxicity.
