These rules are copied from the 2016 edition, so the current edition section numbers will be different. 6.5.3.1* Pipe, fittings, valves, and devices to be joined with grooved couplings shall contain cut, rolled, or cast grooves that are dimensionally compatible with the couplings. 6.5.3.1.1* Pipe, fittings, valves, devices, and couplings that conform with or are listed in compliance with standardized groove specifications shall be considered compatible. 6.5.3.1.2 Other groove dimensions and grooving methods shall be acceptable in accordance with 6.5.5.1. 6.5.3.2 Grooved couplings, including gaskets used on dry pipe, preaction, and deluge systems, shall be listed for dry service. Coupling manufacturers are required to observe these dimensionally compatible specifications so that any manufacturer’s couplings or fittings will work with any other brand. As always, the opinions expressed herein are my personal opinions and may not be considered as the opinion of NFPA or its committees. This opinion should not be considered or used as consultation services.
