Gasket and sealing materials for push-fit fittings receive NSF certification

Feb. 7, 2013

ANN ARBOR, Mich. — Push-fit fittings are used to connect various pipes used in drinking water distribution systems.

ANN ARBOR, Mich. — NSF International has certified the first gasket and sealing materials used with push-fit fittings to both the chloramine resistance and tensile strength performance requirements of ASSE 1061 and ASTM F2854, according to a press release.

Push-fit fittings are used to connect various pipes used in drinking water distribution systems that require the use of gasket materials to ensure a water-tight seal, such as PEX, copper, CPVC or PE-RT. 

Superior Seals’ EP 1/1/5 and EP 11/01/13 gasket and sealing materials are the first to earn NSF certification to the material requirements of both the ASSE 1061 and ASTM F2854 standards, which will save Superior Seals’ customers time and expense.

The NSF certification provides push-fit fitting manufacturers with certified gaskets that have a demonstrated ability to resist degradation from chloramine-treated drinking water as well as validation of their tensile strength.

"NSF International has tested and certified more than 900 gasket materials to the NSF/ANSI 61 standard. Now with the addition of performance testing to standards ASSE 1061 and ASTM F2854, gasket manufacturers can combine their testing needs and demonstrate compliance to all of the standards required by regulators and their customers," said Nasrin Kashefi, general manager of NSF International Plastics and Mechanical Plumbing Certification Programs.
