Rubber Hub Coupling For Plumbing Drains 

Excellent excellent excellent video!!! “Thank U” I’m a 71 yo female who has never done anything plumbing related. My under kitchen sink area has sprung a leak. I don’t have $ to hire a plumber! I was taking it all apart, bought the pipes & fittings I’ll need but broke the pipe that comes out of the floor & into a larger fitting. I just bought a fitting like the one in ur video but didn’t know if I needed goop or tape to repair it. It didn’t come with any instructions lol so thanks again!!

great job explaining this. It was exactly what I was looking for. I didnt know they made flex couplings to go over sockets.

Butt-saving information! Excellently presented too. I didn't get a new kitcgen sink but I have a galvanized 1-1/2" nipple completely holed thru on the bottom by rust & corrosion just outside the hub. Getting it out was a battle but worse was how much of the threads had become one with the hub threads. Like there were NO fenale THREADS left in the bottom of the hub fitting. Thank u for the perfect solution!

Thank you so much for making this video! Best solution to cracks by the hub!

Exactly what I was looking for. Thank you.

Hey I want to thank you for the vid, I found it very useful as I am doing plumbing right now, have a good day!

Great video, it's amazing that of all the information on the net and RU-vid, I couldn't get a simple explanation of a 'hub' coupling. Many definitions of 'no hub' just not 'hub'.

Very helpful info. Thank you! A demonstration of using a ram bit would be nice. Have a good day!

Refreshing 😊

Thanks

Very good. Work. Sir

Nice video and good demonstration. But what I find these rubber couplings useful for is to make permanently accessible section of drain pipe which can be removed at will by just loosening the rubber coupling. There are troublesome section of pipe where it tends to clog badly and very hard to reach with snake, then having easy, direct access to that section of pipe solves lots of problems.

Great Video. What if the T was metal and had threads at the end for the 1.5" metal slip joint nut?

Thanks for the information, do I need to apply silicon or any adhesive for these flexible parts? Thanks

would a 6 inch flex hose be long enough to heat up get a coupler in between 2 hard pipes that have no flex?? I currently have a rubber boot like your showing with clamps in between two hard pipes. Not sure if it will hold it's on a hot tub plumbing under high pressure

So if I were to use this for a snorkel on a ATV will the seal hold up under water?

Do you recommend to use pvc cement to glue this?

Can you use a rubber coupling in a pond? I need to go from a 1 1/2 barb on a 2600 GPH pump to a piece of same size DWV PVC Pipe that goes to the filter. Same at the pond filter, to bridge across a small gap between same size PVC. No problems with the coupling sliding on smooth PVC. I need to be able to easily disconnect at each end for maintenance.

Im wondering... Can i use it underground ? If so how long would it last? Ive never used one of those before

Thanks Sir, that was very helpful. Will certainly look out for one of those connectors. Was never 💯 certain about connecting over a hub , but it appears that that is precisely what those connectors are made for, situations just how you explain it , and the exact situation I was in dealing with a sink drain pipe connection, thanks again, just out of curiosity, are you a licensed plumber, and or do you have any information about CSST pipe tubing , I am interested in changing over from black pipes to CSST , but am not sure If I can use the same exact size of the pipe diameter that is in current use??

But what about a tub to shower MOD? Going from 1.5 to 2 inch drain. All that is left is a .75 to 1 inch nub on the main drain line to connect to. Can you use this rubber coupling to transition to the 2 inch drain line from the leftover nub without having to chop out the main drain tee and install a new one with a 2 inch to connect to?

Is the nut on the band particular size? Is it a quarter inch socket?

@PlumbingPartsPro does this work for ABS pipes? Alternatively, is there an ABS option?

I have that on my drain pipes and can’t get it off! Any tricks you know to help me loosen it so I can snake my clogged pipe

Saw these under the kitchen sink in the house I live in (I rent) it gave out and flooded the cabinets. Is this normal?

does it work on brass drain lines?

❤❤❤❤

Would adding sealant/dope reduce the likelihood of leaks or improve the long term reliability of mechanical coupling?

Hello, wondering if u can help? i have old cast iron kitchen sink. the plastic that connects drain to the pipe cracked hard plastic that connects drainer to pipes, th strainer/drain isnt threaded, do u have anything i can use to connect the 2, thank you

Im still struggling to understand what no hub means. Is the hub simply the pipe you want to connect to or from?

Thanks you just saved me from calling a plumber

How long do those rubber couplings last?

Anyone have a link? Can’t find it.

I cannot find a rubber coupling that will fit 2 3/4 in Galvanized elbow a little bit sticking out of the wall. I only find 2 inch to 1 1/2 inch reducer.

Great video! Is there a version of a Fernco coupling that will slip inside a hub fitting (as opposed to sliding over it)?

Does anyone know how long these rubber couplings last? Particularly when using them on old cast iron pipe to PVC.

Thank-you what glue should one use to plastic to copper

will it work on a outdoor connection,like extending a vent on a roof?

Does the old pipe create a edge that might catch toilet paper etc?

Is Rubber hub qualified plumbing code ?

don't see link for the coupling

This was extremely helpful because I thought my plumber was crazy because there’s a large gap in the piping that he covered with that rubber coupling, so I was like WTW is he doing 😂😂😂

@PlumbingPartsPro Does the work for metal pipes?

How long do those rubber couplings last? Do they deteriorate overtime? Is it a permanent fix?

and these can be burried?

Does this past plumbing code?

I have a question. I am in the process of redoing a roman tub installation. The piping job was badly done, none of the connectors were cemented, causing water to seep out the plumbing and causing wood rott to the wood structure the tub was connected to. The issue I am having is the main drain line that connects to the tub drain needs to be at an angle, will these rubber connectors work to get the neccessary bend for the down drain line without having any leaks at the tub drain connecting point. The tub was raised above the floor, which makes the main drain line come up at an angle. I feel that a 20 maybe 30 degree angle is what I need for the down drain line to make secure connection.

As a Pro I'm feeling resistant to use a coupling that goes over the hub. Feels like cheating. There has been scenarios where I definetly would use this when there's absolutely no practical way to remove the fitting and install new.

Can I use the rubber under a house where it won't be accessible again?

Suage pipe that's what I did

Thanks
