Abstract
This specification covers mechanical cold expansion insert fitting with compression sleeve for cross-linked polyethylene (PEX) tubing. Fittings shall be made from specific copper alloy for machined brass fittings, forged brass fittings, and compression sleeves. The fitting shall conform to the specified dimensions, tolerances, maximum angular variation, solder joint ends, workmanship, finish, appearance, assembly, quality, and marking.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
1. Scope
1.1 This specification covers mechanical cold expansion insert fittings with compression sleeve suitable for use with cross-linked polyethylene PEX plastic tubing in 3/8, ½, 5/8, ¾ , and 1in. and larger nominal diameters that meet the requirements of Specifications F876 and F877. These fittings are intended for use in 100 psi (689.5 kPa) cold and hot water distributions systems operating at temperatures up to and including 180° F (82°C). Included are the requirements for materials, workmanship, dimensions, and markings to be used on the fittings and compression sleeves
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.
