(Specification)Standard Specification for Cold Expansion Fittings with PEX Reinforcing Rings for Use with Cross-linked Polyethylene (PEX) Tubing
Standard Specification for Cold Expansion Fittings with PEX Reinforcing Rings for Use with Cross-linked Polyethylene (PEX) Tubing
ABSTRACT
This specification covers cold expansion fittings and cross-linked (PEX) reinforcing rings for use with cross-linked polyethylene (PEX) plastic tubing in specific nominal diameters. These fittings are intended for use in residential and commercial, hot and cold, potable water distribution systems as well as sealed central heating, including under-floor-heating systems. The PEX reinforcing rings shall conform to the required density, degree of cross-linking, and stabilizer migration resistance.
SCOPE
1.1 This specification covers cold expansion fittings and cross-linked (PEX) reinforcing rings for use with cross-linked polyethylene (PEX) plastic tubing in 3/8 , 1/2 , 5/8 , 3/4 , 1, 11/4 , 11/2 in. 2, 21/4 , and 3 in. nominal diameters that meet the requirements of Specifications F876 and F877. These fittings are intended for use in 100 psi (690 kPa) cold- and hot-water distribution systems operating at temperatures up to and including 180°F (82°C). The system is comprised of a PEX reinforcing ring and a cold expansion fitting. Included are the requirements for materials, workmanship, dimensions, and markings to be used on the fitting components. The components covered by this specification are intended for use in residential and commercial, hot and cold, potable water distribution systems as well as sealed central heating, including under-floor-heating systems.
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.3 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 and health practices and determine the applicability of regulatory limitations prior to use.

polyethylene (PEX) plastic tubing in ⁄8, ⁄2, ⁄8, ⁄4, 1, 1 ⁄4, 1 ⁄2 in. 2, 2 ⁄4, and 3 in. nominal diameters that meet the requirements
of Specifications F876 and F877. These fittings are intended for use in 100 psi (690 kPa) cold- and hot-water distribution systems
operating at temperatures up to and including 180°F (82°C). The system is comprised of a PEX reinforcing ring and a cold
expansion fitting. Included are the requirements for materials, workmanship, dimensions, and markings to be used on the fitting
components. The components covered by this specification are intended for use in residential and commercial, hot and cold,
potable water distribution systems as well as sealed central heating, including under-floor-heating systems.
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical
conversions to SI units that are provided for information only and are not considered standard.
1.3 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 and health practices and determine the applicability of regulatory
limitations prior to use.
