All Custom Gasket supports NSF 61 requirements

 

All Custom Gasket takes the best available material and carefully engineers it into gaskets designed to customer specifications. The result is a quality product that exceeds customer expectations. All Custom Gasket proudly offers compressed non-asbestos fibre brands from Garlock® , Teadit® and Durlon® & elastomeric materials which comply with the NSF/ANSI Standard 61 for drinking water system components & Potable water applications. Applications vary from Water & Wastewater, OEM services, Food & Beverage, Pharmaceutical, Chemical Processing, Mining, Pulp & Paper, Power Generations, Nuclear & more.

 

NSF 61 Certified

 

All components in water treatment or water distribution products manufactured, sold or distributed in North America are required to comply with the NSF/ANSI Standard 61: Drinking Water System Components. This standard is designed to ensure water is clean, safe & that gasket materials meet any application for various safe drinking water systems.

 

NSF 61: Compressed Non-Asbestos

 

  • GARLOCK MULTI-SWELL® Style 3760-U, made of aramid fiber with a proprietary rubber binder which is designed to swell upon contact with water or oil to create a seal. Multi-swell ™ Style 3760-U can withstand continuous temperatures of  +400º F (+205º C) & is ideal for compressors, generators, pumps, gear boxes, transformers and more. Available in 1/64”, 1/32”, 1/16” & 1/8” thickness.
  • GARLOCK GYLON® STYLE 3505, is the oxygen service version of Gylon 3504, an NSF 61 & FDA compliant restructured PTFE material with glass microsphere fillers, is compressible enough to fill in voids and seal imperfect flanges. This style has excellent dielectric resistance which can be used in pipelines requiring cathodic protection. Gylon 3505 is also available in EPIX® & Stress Saver ® Styles.
  • TEADIT® NA1082 SAN, made of compressed fibre sheet technology, is specifically formulated to meet NSF 61 criteria for sealing materials & conforms to US FDA 21 CFR 177.2600. This material withstands continuous temperatures of +500º F (+260º C), has a strong dielectric rating & provides excellent resistance to conductivity. Available in 1/64”, 1/32”, 1/16” & 1/8” thickness.
  • TEADIT® TF 1572 SAN is a structured PTFE with hollow glass microspheres. Withstanding a maximum temperature of +500º F (+260º C), this material has a high level of fibrillation to overcome creep relaxation & cold flow problems. Available in 1/16” & 1/8” thickness.
  • DURLON® 7910 is a compressed fibre sheet made up of aramid/inorganic fibers & an NBR binder. This material was designed to meet NSF/ANSI 61 requirements for potable water applications 73ºF (23ºC) to commercial hot 180ºF (82ºC). It is ideal for applications that come in contact with potable water, steam, oil, water, mild alkalis and acids, hydrocarbons and solvents.

 

NSF 61: Elastomeric & Thermoplastic Materials

 

  • AB-576 EPDM meets NSF/ANSI 61 standards for potable water, has excellent resistance to heat, ozone & sunlight. This premium grade rubber also meets ASTM Grade D2000: 1BA715Z1 (Z1 = Duro 75+/-5 Shore A), ASTM D1330 GRADES 1 & 2 and AWWA STANDARD C111/A21.11 (TABLE 4). Available in 1/16”, 1/8”, 3/16” & ¼” thickness.
  • Santoprene NSF 61 grade is a Thermoplastic Elastomer (TPE) that offers flexibility and durability consistent with natural rubber. A blend of polypropylene & EPDM rubber allows this material to have the advantages of both a rubber & a thermoplastic. It is designed for use in potable water applications & for food processing equipment (Certified to NSF 51: Food Equipment Materials). Available in standard ASME/ANSI flange gaskets, custom sizes, sheets, rolls or profile extrusions.  
  • Garlock Stress Saver® XP, a single piece molded design with raised ribs, made of a proprietary blend of fluoroelastomers, is used in potable drinking water, steam, & aggressive chemical applications. This style requires lower seating stress to seal in flat face non-metallic flanges & can withstand temperatures between -15º F(-26ºC) to 400ºF (204ºC). An NSF 61 certified gasket which carries the Lubrizol FBC™ System Compatible certification makes this stress saver ideal for use in Corzan (CPVC) Piping. Also available in 3522, a 100% restructured PTFE offering excellent chemical compatibility & crush resistance.
