|Publication Date:||1 November 2018|
|ICS Code (Metal fittings):||23.040.40|
This speciﬁcation covers metal insert ﬁttings and copper crimp rings for use with cross-linked polyethylene (PEX) tubing in 3⁄8, 1⁄2, 5⁄8, 3⁄4, 1, 11⁄4,1 1⁄2, and 2 in. nominal diameters that meet the requirements for Speciﬁcation F876 or F3253 and for use with polyethylene of raised temperature (PE-RT) tubing in 3⁄8, 1⁄2, 5⁄8, 3⁄4 and 1 in. and 1 1⁄4 in. nominal diameters that meet the requirements of Speciﬁcations F2623 and F2769. These ﬁttings are intended for use in 100 psi (689.5 kPa) coldand hot-water distribution systems operating at temperatures up to, and including, 180 °F (82 °C). In addition, the ﬁttings covered by this speciﬁcation are intended for use in, but not limited to, residential and commercial systems, reclaimed water, ﬁre protection, municipal water service lines, radiant heating and cooling systems, hydronic distribution systems, snow and ice melting systems, geothermal ground loops, district heating, turf conditioning, compressed air distribution and building services pipe. The requirements for materials, workmanship, dimensions, and markings to be used on the ﬁttings and rings are also included.
NOTE 1-Other code and regulatory requirements may apply to ﬁttings for speciﬁc applications.
The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are mathematical conversions to SI units which are provided for information only and are not considered the standard.
Compliance with this speciﬁcation requires that these ﬁttings be tested and certiﬁed to Speciﬁcation F877 when used with PEX tubing and Speciﬁcation F2769 when used with PE-RT tubing.
This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
