Garden Hose Threads

FWIW, I’m putting this here for anyone else looking.  I chased down the specs.   The NFPA 1963 spec (Standard for Fire Hose Connections, 2014 Edition) says:



Some fire-fighting organizations use small hose less than 3⁄4 in. (19 mm) nominal diameter fitted with garden hose couplings. Such couplings should have 0.75-11.5 NH (garden hose thread) threads conforming to ANSI/ASME B1.20.7, Standard on Hose Coupling Screw Threads.


I found the ANSI/ASME B1.20.7 spec document from 1993 here and it gave me dimensions that let me produce the 3/4″-11.5 threads using the following National Hose Threads.xml file to put in my AppData\Local\Autodesk\webdeploy\production\<XXX>\Fusion\Server\Fusion\Configuration\ThreadData directory:


<?xml version="1.0" encoding="UTF-8"?>
  <Name>NH Straight Threads</Name>
  <CustomName>NT Straight Threads</CustomName>
      <ThreadDesignation>0.75 11.5NH</ThreadDesignation>
      <CTD>0.75 11.5NH</CTD>


I’ve used the internal threads from this spec and had leak-free mating with standard US home-improvement store hoses using ASA printed with high infill.
