ASTM F1961-02a

Standard Specification for Metal Mechanical Cold Flare Compression Fittings with Disc Spring for Crosslinked Polyethylene (PEX) Tubing

ABSTRACT
This specification covers metal mechanical cold flare compression fittings with integral disc spring suitable for use with four sizes of cross-linked polyethelene PEX plastic tubing. These fittings are intended for use in cold and hot water distributions systems and hydronic heating systems. Included are the requirements for materials, performance, dimensions, workmanship and markings to be used on the fittings.
SCOPE
1.1 This specification covers metal mechanical cold flare compression fittings with integral disc spring suitable for use with cross-linked polyethelene PEX plastic tubing in 3/ 8, 1/2, 5/8, and 3/4 nominal diameters. that meets the requirements of Specifications F 876 and F 877. These fittings are intended for use in 100 psi (689.5 kPa) cold and hot water distributions systems and hydronic heating 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.
1.2 Units—The values stated in inch-pounds 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 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.
