(Specification)Standard Specification for Metal Insert Fittings Utilizing a Copper Crimp Ring for SDR9 Cross-linked Polyethylene (PEX) Tubing and SDR9 Cross-linked Polyethylene/Aluminum/Cross-linked Polyethylene (PEX-AL-PEX) Tubing
Standard Specification for Metal Insert Fittings Utilizing a Copper Crimp Ring for SDR9 Cross-linked Polyethylene (PEX) Tubing and SDR9 Cross-linked Polyethylene/Aluminum/Cross-linked Polyethylene (PEX-AL-PEX) Tubing
ABSTRACT
This specification covers the requirements for materials, workmanship, dimensions, performance, and markings for metal insert fittings with o-ring seals and copper crimp rings for use with SDR9 cross-linked polyethylene and SDR9 cross-linked polyethylene/aluminum/cross-linked polyethylene tubing systems. The fittings shall be made from one of the following metals: cast copper alloys, machined brass, forged brass, crimp rings, or o-rings. Insert fittings shall be joined to the tubing by compression of a copper crimp ring around the outer circumference of the tubing, forcing the tubing material into annular spaces formed by ribs on the fitting. Performance tests shall be conducted on the assemblies to determine the material and dimensional requirements of the specimens. Marking shall be applied to the fittings in such a manner that it remains legible after installation and inspection.
SCOPE
1.1 This specification covers metal insert fittings with o-ring seals and copper crimp rings for use with Cross-linked Polyethylene (PEX) and Cross-linked Polyethylene/Aluminum/Cross-linked Polyethylene (PEX-AL-PEX) tubing in 1/2, 3/4, 1, and 1¼ in. nominal diameters that meet the requirements for Specifications F 876 and F 2262. These fittings are intended for use in 125 psi (861.9 kPa) (PEX-AL-PEX) and 100 psi (689.5 kPa) (PEX) cold- and hot-water distribution systems operating at temperatures up to and including 180°F (82°C). Included are the requirements for materials, workmanship, dimensions, performance, and markings to be used on the fittings and rings.
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 Compliance with this specification requires that these fittings be tested and certified to Specification F 877 and F 2262.
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.
