how and why to use a “TAPERED” tap (NPT thread) National Pipe Thread
HTML-код
- Опубликовано: 16 июн 2020
- Not all tap and die sets are the same. If you’re working with NPT National Pipe Thread, there’s going to be an actual taper on the tap so when you install your faucet or pipe the thread will get tighter and seal. This is a very important feature if you’re trying to make water-tight plumbing.

Count the number of complete revolutions when tapping tapered pipe threads. You don't want the male fitting to bottom out on the shoulder.
You should use a "Close" or 2 in Nipple, instead of using only a spigot. Leaves you more room for error.
Also,
A good way to tell where to stop, is by putting the tap into a clean fitting of the same size. When it gets tight and just about to start cutting stop and mark.
Take whatever you have that is going to go in the hole, in this case the water spigot, and screw it into that same fitting, mark it.
Most likely they will be just about the same. Go with the more shallow marking, and tap it in, shy 2 full turns.
That should get you to where you can still keep cutting to sneak up on what angle you want it to be at. As in straight up and down or like the way you went too deep and it is at a wrong angle. That way you don't have to say "I meant to do that!" or "Yeah I wanted it straight up and bottomed out."
Great info! Quick and to the point! Lobe it.
Like an earlobe?
nice npt tap video... thanks a lot...:)
Thanks great to the point
Hello, Can i use this for internal threading gi pipes
I just bought one nut 3/4 online 2 bucks. Wow 2 bucks each plus shipping cost. And I probably need 20 more. So I am making my own nuts. Just get some cheap thick poly cutting board and cut and use tap threaded like you see in this video. I wanted 3/4 tap and I don't want to buy whole set as I just wanted one size only from Tractor Supply.
Yeah this is one of the most amature thread cutting IV ever seen
Hi! So.. Is there a way to measure how deep to go? Like.. ¿Its the same screw's dept? I.e, screw 1/2inch= hole 1/2 deep? I'm trying to figure that out! Thanks

I need set for 1 inch pipe. Where?
They're nice for service plumbers, refurbishing fucked up npt fittings.
what's size of taper you use in tap
The taper is 3/4" per foot, but
the hole does not have to be tapered to use a pipe tap.
Can you tap steel with that.
That's what they are meant for.
Yeah but you're better off spending a little extra to get a set of high-speed steel taps for steel. These carbon steel taps are kinda weak and wear out pretty quickly.
those finger nails!!!! :-O
Probably from working in garden as I do and my nails do get dirty, too.
god I hate sound petty but cut them... cringe worthy
@@RodeoCowgirl-55he means they are long lol they are gross
@@haydenward8285 No. Don't be prissy. The man works. Many times when people work they need to pick at something, pull things apart, pick things ups and you can't do that with nails that art short. He's not in the kitchen baking pies. Hell lots of women are in the kitchen working with food and long nails. Do you tell them it's gross?
@@AztecWarrior69 Lolol I can be what I want lol if he got nails like that idk what kind of work he doin Lolol scratching backs? Lolol
pretty good. you went just a little too far; you don't want your fitting to thread in to the shoulder, especially not that easily but if it works...🤷🏻♂️. If it starts to leak later, and you can't thread it in further or get it to stop with tape, get a 3/4"(or whatever size) bulkhead. Those barrels should be big enough that the curve won't cause you any problems. Just look for one with a nice thick epdm washer.
I agree, lately I go only as far as I have to so things are tightened up better. Great observation👍
