PTFE Gaskets — FDA Approved

An envelope gasket wraps a PTFE outer layer around an EPDM filler core, providing chemical resistance on the contact surface while relying on the EPDM for sealing memory. A unitized gasket uses a fully bonded one-piece construction of PTFE and EPDM, offering improved installation stability and reduced component movement compared to the envelope design.

Artesian Systems' PTFE tri-clamp gaskets are available in sizes ranging from 1.5" to 12". Envelope and unitized gaskets cover sizes 1.5" through 12", while screen gaskets (20 and 100 micron) are available in sizes 1.5" through 6". Multiple sizes accommodate a broad range of sanitary piping systems and process connections.

No. Artesian Systems' PTFE gaskets are not recommended for use with bolted clamp assemblies. They are specifically engineered for sanitary tri-clamp (sanitary ferrule) connections. Additionally, standard PSI service ratings for sanitary clamps do not apply to connections 1" and above due to PTFE's potential for cold flow under compression.

Artesian Systems' PTFE envelope and unitized gaskets have a shelf life of 10 years from the cure date. To maintain integrity, they should be stored in original packaging in a clean, dry warehouse environment between 65°F and 85°F, away from direct sunlight, and at least 6 feet from electric motors or other ozone-generating equipment.

PTFE tri-clamp screen gaskets are available in 20-micron and 100-micron filtration ratings. Both variants feature a PTFE/Teflon gasket body combined with a 316L stainless steel filter screen. The 20-micron gasket is ideal for finer inline filtration, while the 100-micron version suits applications requiring coarser straining in sanitary piping systems.

Yes. Artesian Systems' PTFE gaskets are manufactured to pharmaceutical and sanitary grade standards. Screen gasket variants have passed U.S.P. Class VI Cytotoxicity testing, confirming biocompatibility for sensitive pharmaceutical and bioprocessing environments. All products comply with FDA 21CFR177.2600, GMP guidelines, and 3A Sanitary Standards where applicable.
