Tuf-Flex Tri-Clamp Gaskets are the worlds only unitized seal, setting new standards for purity, performance and flexibility. Designed to meet critical requirements in pharmaceutical, biotechnology, ultra-pure water, WFI (water-for-injection) and difficult food and beverage processing, Tuf-Flex outperforms other hygienic seals while eliminating costly process interruptions.A Tuf-Flex hygienic seals contact surface is a layer of PTFE grafted to an EPDM rubber inner core. This totally bonded construction provides an exceptionally pure and incredibly flexible seal. By grafting the elastomer with a layer of PTFE, Tuf-Flex will behave like an elastomer but will prevent the product contamination, service interruptions and clean-up costs associated with elastomer seals. Because its elastomer core is protected by a unitized layer of PTFE, Tuf-Flex hygienic seals will not release elastomer extractables or particulates, totally eliminating spalling. The result is an exceptionally maintained sanitary tubing I.D. with no I.D. invasiveness or system contamination, and the PTFE grafted elastomer in a Tuf-Flex seal will maintain I.D. without re-torquing or leaking.Storing Tuf-Flex Gaskets:- Shelf Life: 10 Years from cure date- Store in original packaging in clean and dry warehouse- Do not expose to direct sunlight- Keep more than 6' away from electric motors- Maintain temperature between 65F and 85FTuf-Flex Gasket Standards Compliance:- FDA CFR 21, 177.1550 / FDA CFR 21, 177.2600- U.S. Pharmacopeia Class VI Certification- Cytotoxicity Criteria- ADI Free (Animal Derived Ingredient Free)- USDA Standards- 3-A Sanitary Standards- Current Good Manufacturing Practices (CGMP)Tuf-Flex Tri-Clamp Gasket Features:- -20F to 300F Temperature Range- Flexibility of an elastomer with the chemical resistance of PTFE- Outstanding purity- Seats perfectly- Superior resistance to cold flow and creep
