(Specification)Standard Specification for Metal Insert Fittings Utilizing a Copper Crimp Ring for SDR9 Cross-linked Polyethylene (PEX) Tubing and SDR9 Polyethylene of Raised Temperature (PE-RT) Tubing
Standard Specification for Metal Insert Fittings Utilizing a Copper Crimp Ring for SDR9 Cross-linked Polyethylene (PEX) Tubing and SDR9 Polyethylene of Raised Temperature (PE-RT) Tubing
ABSTRACT
This specification covers metal insert fittings and copper crimp rings for use with SDR9 cross-linked polyethylene (PEX) tubing. All performance tests shall be performed on assemblies of fittings, crimp rings, and PEX tubing. Fittings and crimp rings shall meet the material and dimensional requirements prescribed. The sealing surfaces of the insert shall be smooth and free of foreign material. Fitting walls shall be free of cracks, holes, blisters, voids, foreign inclusions, or other defects that are visible to the unaided eye and affect the wall integrity. Insert fittings shall be joined to PEX tubing by the 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.
SCOPE
1.1 This specification covers metal insert fittings and copper crimp rings for use with cross-linked polyethylene (PEX) tubing in 3/8 , 1/2 , 5/8 , 3/4 , 1, 1 1/4 , 11/2 , and 2 in. nominal diameters that meet the requirements for Specification F876 and for use with polyethylene of raised temperature (PE-RT) tubing in 3/8 , 1/2 , 5/8 , 3/4 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.

401L, 316, or 316L (UNS Nos. S30400, S30403, S31600 or S31603)
5.2 Crimp Rings—Crimp rings shall be made from copper UNS Nos. C10200 or C12200, and shall be black in color or
alternately be identified per 10.2.3.2 of this specification. The crimp rings shall have a minimum allowable hardness of 35 and a
maximum allowable hardness of 45 on the Rockwell 15T scale when measured according to Test Methods E18.
6. General Requirements
6.1 When fittings manufactured according to this specification are intended for use with the PEX tubing, the following sections
of Specification F877 constitute a part of this specification.
6.1.1 Requirements,
6.1.2 Test Methods, and
6.1.3 Retest and Rejection.
6.2 In addition, when a section with a title identical to that referenced in 6.1 appears in this specification, it contains additional
requirements that supplement those appearing in Specification F877.
6.3 When fittings manufactured according to this specification are intended for use with PE-RT tubing, the following sections
of Specification F2769 constitute a part of this specification:
6.3.1 Requirements,
6.3.2 Test Methods, and
6.3.3 Retest and Rejection.
6.4 In addition, when a section with a title identical to that referenced in 6.3 appears in this specification, it contains additional
requirements that supplement those appearing in Specification F2769.
6.5 Dimensions—Any randomly selected fitting or fittings, and crimp ring or crimp rings, shall be used to determine dimensions.
Measurements shall be made in accordance with Test Method D2122, except when determining diameters, which is done by
making measurements at four locations spaced approximately 45° apart around the circumference. Inspection and gauging of
solder joint ends shall be in accordance with ASME B16.18, ASME B16.22, or MSS SP-104.
6.6 General—All performance tests shall be performed on assemblies of fittings, crimp rings, and PEX tubing or PE-RT tubing.
Fittings and crimp rings shall meet the material and dimensional requirements of this specification. PEX tubing shall meet the
requirements of Specification F876. PE-RT tubing shall meet the requirements of Specifications F2623 and F2769 or a combination
thereof. Assembly of test specimens shall be in accordance with 9.1.1. Use separate sets of assemblies for each performance test
requirement.
7. Dimensions
7.1 Dimensions and Tolerances—The dimensions and tolerances of fittings and crimp rings shall be as shown in Fig. 1, Fig. 2,
Fig. 3, and Fig. 4, when measured in accordance with 6.5.
7.1.1 Alignment—The maximum angular variation of any opening shall not exceed 1° off the true centerline axis.
7.1.2 Fittings with Solder Joint Ends—Solder joint ends shall be in accordance with ASME B16.22, ASME B16.18, or MSS
SP-104.
7.1.3 Tapered Threaded Ends—Fitting threads shall be right-hand conforming to ASME B1.20.1. They shall be taper threads
(NPT).
8. Workmanship, Finish, and Appearance
8.1 The sealing surfaces of the insert shall be smooth and free of foreign material. Fitting walls shall be free of cracks, holes,
blisters, voids, foreign inclusions, or other defects that are visible to the unaided eye and affect the wall integrity.
9. Assembly
9.1 Crimp Joints—Insert fittings shall be joined to PEX tubing or PE-RT tubing by the 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. Insert
fittings and crimp rings shall meet the dimensional and material requirements of this standard. PEX tubing shall meet the
requirements of Specification F876. PE-RT tubing shall meet the requirements Specifications F2623 and F2769 or a combination
thereof. The dimensions and out-of-roundness of the crimp ring, after it has been crimped, shall be in accordance with Table 1.
9.1.1 Crimping Procedure—The crimping procedure shall be as follows: slide the crimp ring onto the tubing, insert the ribbed
end of the fitting into the end of the tubing until the tubing contacts the shoulder of the fitting or tube stop. For fitting sizes ⁄8 to
1 1 1
1 ⁄4 in. the crimp ring shall then be positioned on the tubing so the edge of the crimp ring is ⁄8 to ⁄4 in. (3.2 to 6.4 mm) from the
1 1 3
end of the tube. For 1 ⁄2 in. fitting size the crimp ring shall be positioned ⁄4 to ⁄8 in. (6.4 to 9.5 mm) from the end of tube. For

2 in. fitting size the crimp ring shall be positioned ⁄8 to ⁄2 in. (9.5 to 12.7 mm) from the end of the tube. The jaws of the crimping
tool shall be centered over the crimp ring and the tool shall be held so that the crimping jaws are approximately perpendicular to
the axis of the barb. The jaws of the crimping tool shall be closed around the crimp ring, compressing the crimp ring onto the
tubing. The crimp ring shall not be crimped more than once. Each crimp shall be checked to determine conformance to the
after-crimped dimensional requirements of Table 1.
10. Product Marking
10.1 Quality of Marking—The marking shall be applied to the fittings in such a manner that it remains legible after installation
and inspection.
