So the data sheet that Victaulic sent our PM is just as Lamar said, for heads, drops, gauges, etc. only. But, that sheet's dated 1980, where the install manual from Mike is 1988...
When i get a copy of the 1980 data sheet, I'll link it to you guys via dropbox. (PM keeps forgetting to send it to me) The Hooker fittings data seemingly all vanished into a black hole, because you can barely find anything online, even with the proper information. The only other sprinkler product I know of that's like that are Omega heads. Its probably just a coincidence but my gut says these fittings must have been a huge legal liability for the manufacturer. At least with the Omegas you can still see the CPSC website info and news reports, but there are no datasheets or other catalog cuts available online open to the public.
