What joint sealer is best for plumbing?

[@primeHeretic]

Is anyone else's favourite bit when he does the friendly, "Hi everyone" with a bit of a headshake then does that tut then "welcome along to today's video" before starting. 😊

[@cglees]

Love it. Welcome along

[@dereton33]

Thanks you lot, tut tut, I am beginning to look as I might need Val Donegan's rocking chair and slippers, ha ha.

[@Ste2023]

Yea. a lovely warm welcome

[@TryDiy]

Hi Al loctite 55 thread sealing cord is the new version of hemp, it's great stuff.

[@dereton33]

I will check it out

[@TheDoosh79]

Yes it's good stuff, use that for threads and PTFE tape on olives.

[@wookieecantina]

Thank you, your experience and advice is dearly appreciated. Cheers, Mate!

[@dereton33]

No worries!

[@chrisholt2474]

Yep, I agree I use the Fernox too, never had a single problem with it or the joint. 🍻👍👍

[@dereton33]

Thanks Chris.

[@cglees]

Sound advice!! I personally always wrap PTFE around my olives 4-5 times. I’ve heard some people like to dip their olives in boss white but I’m not flexible enough to try that 😜

[@dereton33]

Do whatever suits you best.

[@Del-gl2cu]

Great advise as always dereton, I'm with you on this one, I always use Boss White (still available in B&Q) on compression joints, it never fails & is far less fiddly than PTFE tape 🙂

[@dereton33]

My go to stuff.

[@JohnSmith-ox7xc]

I've tried a joint compound recently to see if it was better than PTFE tape. Very messy to apply, hard to clean off fingers, and doesn't want to stay where it's applied. Maybe this is specific to this product, but given this one experience, I think I'll use PTFE going ahead in future as a first resort. Just easier to handle.

[@dereton33]

OK thanks John.

[@1flu1]

I've been lucky enough to never have any leakage. However after watching this video, I think I'll start and put a blob of paste on the olive. Thanks for the good advice 👍

[@dereton33]

No problem.

[@JairoABennu]

You saved me with PTFE tape once. I had a stopcock, massive pressure under the sink, it was pumping so hard the pipes were moving as though possessed by an evil spirit. Leaking constantly, I looked up your advise and then it was all perfect daisies

[@dereton33]

That`s great.

[@bikemancambs]

Fernox LS-X is my fav never had a problem

[@matthewgartell6380]

Same here. Never had an issue. Used it other day on mechanical fitting joining 11lb lead to 25mm mpde

[@dereton33]

Great stuff guys.

[@sheepfarm7560]

Hi Al brilliant again I did purchase the fernox jointing compound over the years and it’s brilliant thank you again for your advice see you soon David

[@dereton33]

Glad to help Cheers David.

[@JerGoes]

I agree entirely, as belt and braces put a bit paste on compression fittings, I'm not a plumber admittedly but I feel a complete noob whenever I do it, but I'd rather tighten up once and know it is sealed without having to worry.

[@dereton33]

Thanks.

[@happyman1272]

I've always used Fernox LS-X jointing compound on compression joints, it looks like a silicone gel, i'm only a DIY person, but never had a leak. Fitted probably 10 bathrooms in my life.

[@dereton33]

Yes good stuff.

[@nigelsmith6413]

I’ve only ever put PTFE around the screw thread. Surprised to hear this.

[@dereton33]

Happens all the time.

[@PROPOSITONMAN]

Laco slic tite I'd recommend comes with a brush compound with ptfe inside aswell, LSX very good for male threads

[@dereton33]

Thanks.

[@6581punk]

Never knew of these. When I was updating my bathroom I removed an old toilet waste pipe and it was sealed in place with lead.

[@dereton33]

That would have been the old way of sealing it. Lead caulking we called it.

[@stuartlockwood9645]

Hi Al and Jan ☺, always good to see you mate, and it's the never ending dilemma Wether to use a joint sealer or not,lol. As for myself I'd rather give it full belt and braces, obviously whith potable approved paste, and or ptfe, or if I'm in doubt both, ha ha, I'd never forgive me self if I had to re,do the joint, especially if that involved draining down the pipework again to reseal it. When faced with a compression fitting for the first time the novice diyer doesn't realy know how tight to make the joint, or understands just what's happening inside the fitting when they apply spanners to it. I can't remember if you've already made a video showing the proper procedure, but I'm sure your advice would be greatly appreciated anyway. Cheers Al, stay safe mate, best wishe's to you and Jan, Stuart UK.

[@dereton33]

Hi Stuart hope you are keeping well. I will sort a video out on that tightening a fitting.

[@stuartlockwood9645]

@@dereton33 Hi Al and Jan, thanks for the reply, I'm not doing bad for a 74yr old duffer whith cardio problems, just slowing me down, which is taking some getting used to, but I'm growing old disgracefully so the family tells me, well that's my excuse and I'm sticking to it, ha, ha. I hope you and Jan are ok too, and I'll look forward to your next video, Atb, Stuart UK.

[@roybatty2030]

Another great vid from the boss. Nothing like a bit of hemp in your joint!

[@dereton33]

Always. Ha ha.

[@davidplanet3919]

Thank you. In my DIY plumbing I’ve been using potable jointing compound (flomasta) on olives (not threads) and only used PTFE on radiator tails with tapered threads. Still learning though.

[@dereton33]

That is all fine Dave.

[@craigwatson7692]

Threaded fittings - liquid ptfe or just ptfe. You don't need anything else Compression joints - couple wraps of ptfe around the olive or some paste (I prefer Swan seal by black swan) and you'll be fine.

[@dereton33]

Thanks Craig.

[@safirahmed]

There were videos somewhere about using jointing compound on the inside collar of a water supply pipe and it may be useful to provide links to the videos with the merits of different types of washers nylon, rubber, fibre and where to place the compound paste and potential problems.

[@dereton33]

Great idea.

[@pj8964]

You can still use it as a Halloween wig right 😉🤣. Actually I avoid using Polytetrafluoroethylene tape it`s a rookie move and it gives a poor appearance. and I will only use it if the thread machining is a sloppy fit. Always check fitment first and then type of metal. I would always recommend greasing the thread as that alone will usually result in a leak free joint. Anyhow that`s my humble opine. Keep up the great work Mr. Al as I always look forward to your video`s. 👍👍👍

[@pj8964]

[@ww4407]

I used loctite 55 on some threaded radiator tails. I needed to remove one but couldn’t because the loctite 55 makes such a tight fit. I will use PTFE if I ever do these again.

[@dereton33]

Thanks for the tip.

[@BobWynn]

I had a leaking radiator years ago and a neighbour wound some string round which stopped the leak. Unfortunately the rad is permanently on!

[@dereton33]

Good stuff that string, ha ha.

[@karlsands1714]

Hi Al, I'm confused as to which fernox sealing compound I should use. There seems to be a yellow tin and a blue tin. Which one is for drinking water pipework and which one is for central heating pipework and is there one that does both. Many thanks 😊

[@dereton33]

The blue can do Both .

[@karlsands1714]

Many thanks 😊

[@cyclingSausage]

I definitely wouldn't use nothing on compression joints no matter what the manufacturers/experts say. I always tighten the joint, loosen it again, wrap ptfe around the olive and tighten it back up.. Takes longer, but it works for me.

[@dereton33]

Ok Thanks.

[@aw9951]

Hi Al, Enjoy you videos and appreciate the many years of experience in the plumbing trade. Wanted to ask why they make a non potable version of paste when surely you can use the potable version for all jobs. Cheers, keep the videos coming.

Now that is a question and you know what? I dont know.

Hi Al, please would you tell me if this is right? I'm about to put LS-X Fernox Jointing Compund on the olive of an elbow isolation valve on the potable water in the kitchen? (I have PTFE tape too just incase) Thank you.

[@dereton33]

Just the jointing compound is enough. Do not use PTFE tape and boss compound together.

[@sunkat76]

@@dereton33 Thank you so much. When it says fit the isolation valve with the arrow in the direction of flow does that mean the arrow is pointing towards where the water coming FROM the rising main. Or, towards where the water is going TO the tap? thank you.

[@Catstorm99]

It's to indicate the direction of flow of the water, so in this case the arrow would be pointing to where the water was going (the tap)@@sunkat76

[@sunkat76]

@@Catstorm99Thank you ver so much! I am about to put a lever isolation full bore valve but there is no arrow on it?? Any ideas please? Also as the existing isolation valve is corroded I will need to turn off the header tank gate valve but this is not shifting either. Do I turn off the main stopcock and the boiler too? All i want to do is replace the isolation valves and install a kitchen tap. Thanks.

why no ptfe on the first thread shown, "thats a no-no!", but you then say its alright around the next thread?

You may be best to watch it again. That thread was the coupling nut where the nut and olive goes.

[@markatchison9974]

Over the last 10 years or so, more & more brass & copper fittings are made from recycled metal in China & they're not good quality, which is why I think it's more important than ever, these days, to use some kind of additional seal IF you're going to guarantee your work for 5 years or more.
