Food Grade PTFE Gaskets

An envelope gasket wraps a PTFE outer layer around an EPDM filler core, providing flexibility and anti-creep properties. A unitized gasket bonds PTFE to EPDM in a one-piece construction, improving installation stability and reducing component movement. Both designs outperform solid PTFE gaskets in sealing memory and long-term performance.

Yes. All Artesian Systems food grade PTFE gaskets are designed specifically for tri-clamp (sanitary ferrule) connections. They are available in sizes from 1.5" up to 12" to accommodate a wide range of sanitary piping systems. They are not recommended for use with bolted clamp assemblies.

Artesian Systems offers PTFE tri-clamp screen gaskets in 20-micron and 100-micron filtration ratings. Both feature a 316L Stainless Steel filter screen bonded within the PTFE gasket body, providing inline filtration while maintaining full FDA 21CFR177.2600 and 3A compliance for sanitary processing lines.

Yes. Standard PSI/1550 PSI service ratings for sanitary clamps do not apply to connections 1" and above when using any PTFE-based gasket, due to the potential for cold flow under high pressure. This restriction does not apply to fractional 1/2" and 3/4" connections, which use a recessed, fully contained design.

Artesian Systems' PTFE-EPDM gaskets have a shelf life of 10 years from the cure date. They should be stored in original packaging in a clean, dry warehouse between 65°F and 85°F, away from direct sunlight and at least 6 feet from electric motors to prevent premature material degradation.

Yes. The PTFE screen gaskets have passed U.S.P. Class VI Cytotoxicity testing, confirming biocompatibility for sensitive pharmaceutical and bioprocessing environments. All products comply with FDA 21CFR177.2600 and are manufactured in accordance with GMP guidelines, making them appropriate for regulated pharmaceutical and life sciences operations.
