ASTM F2098-15

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
Designation: F2098 − 08 F2098 − 15
Standard Specification for
Stainless Steel Clamps for Securing SDR9 Cross-linked
Polyethylene (PEX) Tubing to Metal Insert and Plastic Insert
1,21
Fittings
This standard is issued under the fixed designation F2098; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
1. Scope
1.1 This specification covers stainless steel clamps for use with fourfive sizes of insert fittings that comply with F1807 or F2159,
and cross-linked polyethylene (PEX) plastic tubing that complies with F876 or F877. These clamps are intended as an alternative
to the copper-alloy crimp-rings of Specifications F1807 or F2159for use in 100 psi (689.5 kPa) cold- and hot-water distribution
systems operating at temperatures up to and including 180°F (82°C). Included are requirements for materials, workmanship,
dimensions and marking of the stainless steel clamps; requirements for deforming the clamps; which apply to assemblies of PEX
tubing and Specifications F1807 and F2159, insert fittings secured with deformed clamps per this specification.
1.2 The values stated in inch-pound units are to be regarded as the standard. The SI values statedgiven in parentheses are
mathematical conversions to SI units that are provided for information purposes.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.
