1.1 This specification covers metal insert fittings and copper crimp rings for use with cross-linked polyethylene (PEX) tubing in 3/8, ½, 5/8, ¾, 1, 1 ¼, 1½ , and 2 in. nominal diameters that meet the requirements for Specifications F876 and F877and for use with polyethylene of raised temperature (PE-RT) tubing in 3/8, ½ , 5/8, ¾ 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) cold- and hot-water distribution systems operating at temperatures up to, and including, 180°F (82°C). The requirements for materials, workmanship, dimensions, and markings to be used on the fittings and rings are also included. 1.2 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. 1.3 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. 1.4 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. |
