New Standard Specification Available for SDR9 Cross-Linked PEX Tubing

On Dec. 10, 2001, ASTM Committee F17 on Plastic Pipe Systems approved F 2159, Standard Specification for Plastic Insert Fittings Utilizing a Copper Crimp Ring for SDR9 Cross-Linked Polyethylene (PEX) Tubing.

According to committee member Matthew D. Cantrell, piping specialists developed the standard to provide a corrosion-resistant alternative to brass or copper insert fitting systems in the PEX plumbing market. “Users will be able to specify a fitting design compatible with any CTS-OD controlled SDR9 PEX that is non-metallic and is therefore compatible with even the most aggressive water chemistry,” he said.

Cantrell, a product engineer, developed the specification with PEX manufacturers, injection-molding engineers, applications engineers, plastics consultants, and materials specialists under the guidelines of ASTM Subcommittee F17.10 on Fittings.
