NFPA 13 2016 edition section 6.5.3.2 only requires the couplings to be listed for dry system use. If the coupling is listed for use in dry or precaution systems it is fully acceptable to be used. Some manufactures will suggest to use a “Flush or Tri-seal” gaskets in cold storage or freezer applications to prevent the water build up in the gasket itself. Ultimately, not a code requirement.
The above is my opinion and has not been processed as a formal interpretation in accordance with the NFPA Regulations Governing Committee Projects. This is provided with the understanding that the AFSA assumes no liability for this opinion or actions taken on it and they are not to be considered the official position of the NFPA or its technical committees. AFSA cannot provide design or consulting engineering services, and this opinion should therefore not be considered, nor relied upon, as such. > On Apr 30, 2021, at 7:42 AM, Taylor Schumacher via Sprinklerforum > <sprinklerforum@lists.firesprinkler.org> wrote: > > I'm digging through coupling data sheets and I'm seeing that most are listed > for use in wet and dry systems even when they do not have the gap seal.
