How to Make Gas Pipe connections 

The Great Hacker always tells all his trade tricks ! He is a great instructor !!

You need a longer flex bud that things gonna break

That flexible connector is way too stretched and will split , it's just a matter of when.....!!!!!

Always use yellow tape/dope because it's helpful to identify what's in the pipe especially for safety. That's the main reason. Also yellow tape or paint goes a long way as bonus.

Way too much tension on that flex pipe, you need a slightly longer iron pipe.

You sir are the cat's meow. Excellent job! Now I know what to use and what to do. Thank you so much for sharing.

Pretty sure installing a gas connector with that kind of tension clearly violates all applicable fuel gas codes. Never ever do this...

Better to put in a new pipe and have slack In the flex pipe.....

Great video. Thank you.

Looks like the flex my not have enough flex. Vibration from unit may create leak after several uses.

Cool as a cucumber; good detail instructions

Good video , you like your soft set dope ,should switch to PLS2 for gas

I remember back when I started my apprenticeship some 43-years ago, using Rectorseal No. 5; it filled the gaps between the connections of the pipe threads and was a great lubricant/sealer, for which it was designed for. A few year later, along came Teflon (white) tape- a few wraps around the threads without having to use any compound- was an acceptable and approved practice in the trade (in my area) by the gas company and building inspectors. Of course, now in my area, today's standard requires the use of gas-rated Teflon tape (yellow) and pipe thread compound. You have to use both. If you buried black iron pipe for gas, the piping was yellow plastic coated, and a yellow-coated mastic adhesive tape had to be wound and overlapped around any exposed pipe and fittings; that was, until the advent of Gastite PE underground piping. As was the requirement then, as it is now, for test pressure/leakage, the installer must charge the line with 15 p.s.i. of air using a 30-lb test gauge and it must hold the pressure for 30+ minutes without any pressure drop. Of course with direct burial, there are many requirements needed to be fulfilled for inspection approval; such as the depth (42"), sleeved in a clear sch. 80 x 6" round PVC pipe; whereas the 6" pipe must be laid in a 6" bed of sand, and a tracer line attached to the underground gas pipe. (Of course, you have to use natural gas risers and brackets, etc.).

GOOD EXAMPLE OF WHAT NOT TO DO !!!

Way too much pressure on that flex pipe. Doesn’t allow for any vibration or movement. Go get a longer extension piece.

That flex connector is not designed for outdoor use. Also just for information stainless steel flex connectors can corrode. Use Dormont with PVC coating

Ouch! Nothing worse than a preloaded line! I would never pull on the pipe going into the generator either!

The purpose of flex type is not to be under any pressure like any. Imagine if you live in earthquake zone.

Man! That is too short.. dont leave it like that

Where do you get those made in usa black pipe fittings?

should use non-corrosive leak test solution

Will this work for air compressor fittings? My compressor goes to 150 PSI

im learning. make it work . i do agree that looks short i usaully see alot more slak at other homes. just saying

That's a nice jacket Hacker. 👍 You and your fancy Knipex pliers getting it done. They almost screwed you on that. It was a close one. Happy Thanksgiving buddy.

Can i apply that sealant during winter? The temperature around 32-50

Wow... the way you pull from the flex connector at 7:27 ! It is obviously too short and as a professional that you are, you should have replaced it rather than stretch it like that and keep in tension. That will create a leak!

Good video .

I'm sure you know this but the Pro-dope is not approved for LP gas. That kinda makes it more of a pain because I need two types but I like the easy clean up. Good video Hacker 👍👍

I advise to bathe the entire body of the flex-line with the soap test. Pinhole leaks on the body of the flex-line occur, from the manufacturer to the warehouse. And go with longer nipples so that the flex-line has ample play when fully connected.

You need that union for any future service

1 last comment. Since when are you aloud to use a spring gauge? I’m always required to use diaphragm gauges because they actually show leaks

I have a question, if you’re removing a section of pipe or a flex pipe and one of the pipes you don’t want to remove loosens a little. Can you just tighten up the one that moved a little and just tighten it? Or do you have to remove the pipe that moved a little and re-tape and dope it to reinstall!

Fancy way to stretch pipe...

Also you’re only getting 5 ounces I don’t know where you came up with the higher number?

Settlement???

The best way to ensure you won't get many thumbs up, subscribers, or even return viewers is to find poor workmanship, ignore it, and continue it anyway. The fact that you actually posted this video after showing the flex is too short and not fixing it shows us all we need to know about your work ethics. Ridiculous

Have you heard anything on the new Nylog White? It’s a silicone based sealant that can be used on high pressure refrigeration lines, but also seals gas, air, and water. Supposedly techs are just using this across the board. It’s supposed to stay wet and never dry. I have never used it myself but saw it reviewed by an HVAC School channel.

Run!!!!!!

now days yes, don't use the cheap white teflon on gas lines! years ago the teflon tape came in different flavors of density and width. density is key, which is what all the "born again multi-color tapes are. pay no mind to the tape color but LOOK at the tape and devices to ensure proper UL listings/ratings. oh those are water shutoff valves(on gas line) no look at the ratings stamped on body and handle both :))

1. When the inspector performs the pressure test, are the other appliances disconnected and pipe ends capped off or did you isolate the appliance using their shutoff valve? 2. After the inspection, do you dis-assemble some of the pipes to re-connect all appliances? I heard adding air with appliances connected could damage its valves.

Too much stress on that flex fitting. Don't be that guy, go back and replace it with a longer one.

What happens if you over tighten? And how do you know when you've over tightened?

Where can I buy that flex pipe I need one for my generator. someone installed the generator with an solid non flex pipe

How many threads is a minunim

Hi sir can you give me a list of sealant for gas pipe 🙏

I was asked the other day can you go csst to black hose connector on a garage heater? Anybody ?

Oh. Dear.

Why did you not turn the shutoff valve off? Doing all this work with gas just flowing out? WTF?

While true that residential gas pressure is commonly low, you must secure the pipe to the threaded joints correctly. A great example of this is shortly after at 8:00, you attempted to tighten the "Flare Connection" and all the way back to your shutoff connection untightened due to the connections not being properly tightened! Also, You should have an appropriate sized flex connector as the one you have installed is inappropriately tensioned and is not suitable for application!. As plumbers, we must put our best practices at use all the time! You can do better than this! Good Luck!

Throw that teflon tape in the junk. It gets into valves

Flex is too short

At 4:30 to 5:00, he's taking off the pressure gauge 'before' turning off the shutoff valve on the line . WTF?

I'm appalled your hooking up gas, I'm appalled you made a video.....please get some training. "The HVAC Hacker" is a great name for your channel.....smh

Its a ll trash...grape

Really?.. should have used a longer flex connection. Not good posting bad practices like that.

Dude that connection is not right lol

Nice illustration. Thank you

Η σωλήνα του υγραερίου η αερίου πρέπει να είναι χαλκοσωληνας και όχι σπιράλ δεν κάνει γιατί δεν έχει ενίσχυση είναι μονου τειχωματος ενώ ο χαλκός είναι πιο συμπαγές .

Black iron pipe out

Nope....Definately not a Gasfitter

True Hack. Don't do this.

How did this get so many views ?😂

Hack job.

Way off the mark.

Typical guys always think it’s longer than what it really is. 1 inch more would’ve felt a lot better

Please take this video down. IT shows improper technique. No one should do anything similar to what you've shown. We are all worse off for having watched this.

WINDEX for gas leak testing...insanely dumb and irresponsible
