New Dominos Coming to North America

There is also BSPP - which is a straight thread variant - I don't see this except in UK, Austrailia and Europe and even then it is rare

The BSPP stuff is actually pretty easy to distinguish from BSP. Any semi-competent plumber can recognize a tapered versus straight it just by looking. It is used /mostly/ with washer-style seals while the tapered threads are used only with thread seals. I remember figuring this out while I was like 12 years old when sorting out our taps. Not noticing this is pure sloppiness...

The BSP versus NPT I can see being a much bigger problem - not as easy to distinguish at a glance, I would venture from your description.

Yeah, I have nothing to do with plumbing - I usually get involved when a plant has been built by the lowest bidder and installed one of these bad boys - https://www.ksb.com/en-us/lc/Products/Pump/Ring-section-pump/c/LIP/H63A and the pipefitters (I guess they may be plumberesque) they are definitely not used to seeing BSP in the US and they jam in NPT - figure out it doesn't work - then jam in some combination of JB weld or some other epoxy to get them past commision and get paid. Then the poor bastars who own the plant have to pay us a crap ton of money to refurb those things and drill/tap everything to NPT.

It is all for goofy stuff like oil and water drain lines - but they are under pressure when running so they leak constantly and make a huge mess - so the plant wants them cleaned - but doesn't want to pay and the manufacturer says the installer used the wrong fittings etc so no warranty - big circle jerk and I end up fixing it all.

When they did that, didn't the business owner who paid them complain about it to the highest corporate level possible? Google reviews, BBB (if they are a member of it), etc.are additional avenues to share their story -- in detail.

FWIW...the Vac Sys came from Festool with both BSP & BSPP fittings. This cheat sheet helped me out a lot.

Here are some new Vac Sys fittings ordered from Festool, however once assembled, it's easy to identify the BSP vs the BSPP fittings.
