Just for copper pressure test

Just for copper pressure test

This is just for copper this can be used
to glue copper pipe together so you don’t need to solder it you can use this. I did actually make a video using this several years ago and I have used
this a couple of times to get me out of some very sticky situations and it worked
very well. A few people have commented saying that it’s no good
so what I’m going to do is I’m going to make up a joint and then tomorrow we’re
going to pressure test it using the pressure testing equipment. The
instructions for this are quite specific and they do say that you need to clean
the copper pipe using 60 grit abrasive paper like so, which we’re going to
use, but I’m going to use this end feed fitting and we’re going to make a joint and
then tomorrow after 24 hours have past we will pressure test it and see if it
can withstand the pressure. To start off with I want to take the 60 grit abrasive paper and I’m going to use that to clean up the end of the copper tube. Once you clean that up there is no need
to blow it you can actually leave the residue on there and that will help with
the bonding process. I’ll now clean the other piece up. Then finally
I’ll clean inside of the fitting. Now I’ve done that I want to give the Just for Copper a really good shake. I’m then going to take that and I’m going to apply a really thin zigzag
bead on the inside of the fitting. I’m going to take the copper tube and
we’ll do exactly the same with that. Once I have done that I’m going to push it into the fitting and I’m going to turn it 360 degrees
within five seconds. I am now going to repeat that process on the other side of the fitting. So this time I’m going to grip the
fitting and I’m going to push that pipe in there and then I’m going to twist it 360
degrees within five seconds. I am going to take that and wipe off the excess. Then we’ll leave that until tomorrow. It’s now being 24
hours and that is the joint that we made yesterday. I have now connected this up to the
pressure testing rig and at the end there I have put a washing machine tap and then we can
bleed out the water. So I’m just going to pump the machine now so we get water
coming out at the end. Now we’ve got water there I’m just going to close
the tap. So I will now lift that up so that it’s near the dial so you can watch
the dial at the same time. I’m not going to start to pressurize the pipe. And you can see that straight away we’ve
gone up to ten bar and there’s no sign at all of the joint leaking. We are losing a
bit of pressure from the compression joint on the corner because there’s a
second hand joint. So you can see that the joint is still holding. You get it up
to 20 bar. See there’s no sign at all of the joints leaking. So twenty bars is approx. 290 psi and you can see that that joint is not leaking at all so
I’m just going to take it up a little bit further….. As you can see we are now over 30 bar
which is well over what kind of pressure you will expect to get in any domestic
property. We’re now at 40 bar and the joint is still holding it hasn’t failed at
all. So for those people that say that Just for Copper doesn’t work and that
it’s a lot of rubbish obviously some people have never used it or they have
used it incorrectly. If you prepare the joint as recommended by the manufacturer
and follow their instructions you can see that the joint is perfectly suitable
for domestic plumbing. That’s actually holding a lot more pressure than what
you would get in a domestic situation. At this house we have approximately 90 to
100 psi of pressure. As you can see we’ve got 30 to 40 bar there which is well over
450 psi. I hope you have enjoyed watching this video, if you have and you
haven’t done so already please subscribe to the channel.


  1. Quite a few people have commented saying that just for copper does not work, or does not work well. I have used it a couple of times and it has been really useful in some situations where it was not possible to solder a joint. I thought I’d make this video to see whether or not the just for copper could take the pressure or not and it definitely took the pressure. I’d just like to point out that I’m not affiliated in any way with just for copper. I hope everyone has a great weekend 😉

    Obviously I would not use just for copper to do the plumbing for a whole house as traditional solder joints would be the joint of choice for me, but in some situations this product is superb 😉

  2. Hi,

    A very impressive test taken to a pressure way above normal operating pressure. It would be interesting to learn longevity of such a joint in regular service where copper pipe is subjected to many heating cooling cycles?

    Would the chemicals leach into drinking water?

    Thanks for adding another useful and informative video.

    Kind regards, Colin.

  3. I was worried the whole pipe was going to rupture I hope you where wearing the required PPE I'm surprised copper pipes can take that pressure great video chez

  4. wonder if loctite would do the same job? though i dont get why it needs to exist, we have compression fittings, but i guess options are good for that super tight location

  5. I normally use compression or tectite fittings but that stuff is astounding. What type of "joiner" did you use please ?

  6. That's pretty impressive. I wonder how well it holds under some disturbance and contraction of hot and cold pipes. I remember you showing this last time round and I couldn't believe it. Thanks for doing the demo.

  7. Wow, I have never heard of this product, I have in the past used compression fittings as I am no good at soldering.Thank you for showing this product that I am going to get ASAP and save myself a small fortune on copper fittings. I know you are in the UK, where did you buy yours from please. Keep up the great videos, they are very enlightening.

  8. Might be worth retesting the same joint in six months then a year. This was a great demonstration of this product, though I remain skeptical.

    Also, I hope the criminally incompetent contractors and blind-deaf-dumb code inspectors in my area never learn of this product or they'll be real trouble.

  9. what sort of pressure is in a general central heating setup, say with a combi boiler I thought it was only about 2 bar, 40 bar is just nuts. that's some strong stuff!

  10. It seems that this would be the best solution for joining copper pipes. Is there any drawback such as price or speed compared with other methods? Thanks and awesome video. I'll be waiting for the next!

  11. Fail to prepare, prepare to fail. Great video and I never knew this stuff existed so thank you for letting us all know that there is a product available which can cope in no solder, no compression joint situations.

  12. Never heard of this product, seems really useful for certain situations. Thanks for taking the time to do the testing! All the best!!

  13. Never seen that stuff Chez. Thanks for the vid. Pretty amazing stuff.
    Just as I thought "I wonder when that compression fitting will leak" you said it was,

  14. Trouble is what does it do over the long term though? Just because it holds at the time doesn't mean it lasts.

    In a pinch it's probably useful but I'd always avoid it

  15. Many adhesives stick well when first applied. However, with time, UV, chemicals in the system, aggressive fluxes from other soldered joints – I would be keen to see if this stuff degrades over time. My house has soldered joints that are 60 years old. Would doubt that Just For Copper would still hold after such a period of time.

  16. Hi handyman
    i just purchased a wall mounted basketball hoop. I've tried to use the included sleeved anchors but have failed miserably. Please could you advise me on how to use sleeved anchors

  17. Really surprised that stuff took 40 Bar, even if it took half that i would still be happy using it

    The question now is, what pressure will it actually fail at?

  18. How does connection fair when a shock wave passes through the water line (as when the washing machine suddenly turns off the water flow)? Or when water hammer occurs?

  19. If this product actually holds why would we not use it all the time and not bother with soldering? Is there evidence it may not hold up as long? Or is there just not enough evidence on its longevity to completely trust it at this time? Could this product be like snakebite fittings – allowing home owners to do jobs that required plumbers – or at least the ability to solder – in the past?

  20. Most of the failures of fittings that I come across are due to incorrect installation and not following the manufacturers installation instructions. It's amazing how some people will throw together pipe and fittings that they've never used before without doing a wee bit of research on its correct installation first, and when it fails, they blame the fittings, not themselves. Great video and I'll give this Just for Copper a go. Thanks for sharing.

  21. Is Just for Copper accepted by plumbing inspectors? Is it approved by the plumbing code? Just curious. Glue for copper! Looks like a great product.

  22. First, thanks a lot for this demonstration, Mr Ultimate Handyman! I've used this product for over 12 years now, in situations where soldering is too difficult, like tight spaces, or the proximity of heat sensitive items, but also when the pipes are wet! What a shame this product isn't sold in the Home Depot stores in New Jersey (USA) where I live now.
    I haven't been let down by it so far. Two pieces of ADVICE for the new users:
    1) SHAKE WELL before applying, otherwise there will be unhardened residue outside the bonded surfaces.
    2) Make sure your fittings are in PROPER POSITION quickly, because one can unsolder a fitting, but one cannot unglue it for repositioning.

  23. What about in refrigerant piping? Head pressures don't usually get that high, but I'm curious as to the absolute limit and whether it can contaminate refrigerant? I'll be finishing my program in a few months and I would like an alternative solution to brazing if at all possible.

  24. I was sceptical about using copper pipes for my air compressor lp system. I never thought copper could stand so much pressure!

  25. These types of videos always use cold water over a very short period of time. Obviously we all know that actually the expansion and contraction of pipes due to heat and cold (including exterior and interior temperatures) wears down materials but this is hardly ever factored in.

  26. Been using it since I saw your video. Sooooo how do you un-bond them? I have a small air leak. It was my fault I crushed the pipe a little, though I fixed it..
