I'm surprised you started in the 1800s, and not say with the Roman aqueduct system.

save the "history" for the video end...
Just get to the pipe connection types (as in the title)

So what in a 1/2" fitting actually would measure 1/2 inch? It seems very arbitrary how the actual thread OD and ID measurements correlate to the designated sizes-

Thanks for the video but not really what I expected. I will look on your channel for more sizing videos, hopefully you 'demystufy' why pipe sizes are so strange and confusing. Knowing the sizing names and histor is great but there was very little discussion on actually sizing values here.

I was thinking If I was ignorant! Thanks for the valuable video that indicates I was not wrong! I was crazy Why 1/2 inch ordered, that 3/4 came to me! Then the history reveals: Sir Josef put his finger in the pipe or his something. and says; "Hey! No matter the thread size is, as long as my thing inside the hole, this is 1/2 inch But 3/4 inch!" This is the fucking fundamental, I am trying to find the right product to fit my water block for 7 days, and things coming and going! What the Fuu... If it was an "SI" system, I could figure out in a minute! Common man! Change the fucking ignored mind, turn into science units. People are measuring "Quarks" today!

Metric system would have been so much easier to use. This is stupid. Waste of time and resources

Calling thread male or female--isn't that trans thread phobic? :) Thank you guys, well done.

one of the better videos explaining pipe sizes. thank you

I thought this video would help when he said about the 1/2 inch being 3/4 in the introduction. Watched the whole video and didn't hear an answer to that. Shower hoses are 1/2 but actually bigger. I am trying to find what is the actual name size for a different hose where it's connecting end is 3/4 OD (female) and 5/8 ID. What size t-connector would I need?

Sounds like we need a 3rd Jerk to come along and make a new standard of measurement because this is unnecessarily to complicated.

Thanks for the informative video. History is important to learn for any subject because the more you know, the better you understand. From the past developments to the specifics of current use, all resolutions of understanding will improve your ability to use tools and materials more effectively and efficiently.

2:34 Sellars is a very American name, don't you know?

I wonder if you could help me find answers to the following: 

Thinking to lower the pressure tank and connect to the pump about 10' - 15' under the ground to eliminate the heating well house in the winter season. My pipe runs about 6' under the ground. 1) is it a good idea?  2) how to do it?  3) Should I install another pressure tank under the house in the crawl space? The well is about 30 yards away from the house.

Need advice, , , , I am installing one of your 3/4in Rusco spin filters inline, before my whole house filter cartridge unit. When the Rusco is positioned vertically, I have a very slight leak on the inlet side even though the fit is rather tight. In other words I don't think I can make another complete turn without damage.
Since the Rusco is supported by the pipe plumbing, can't use pex or plastic and I dislike unions.
Is there some type of swivel connector that would have the strength to support the Rusco, but permit me to position the Rusco vertically?
Application is home domestic water system on a well set at 40-60 psi.

What do you do if your fitting is gender neutral? Or non binary?

[bingosunnoon]

Which one of these fittings uses a 7/16-28?

Great video, very informative. Exactly what I was looking for. Thanks a lot.
