Stopping pesky leaks on new compression fittings?

[motorbiking]

I also tighten to squeak point. The worse that can happen is you strip the thread. But if it leaks you were going to need to replace anyway.

Make sure you don’t squash the pipe when you cut it and open the end up a bit with the stabby spear shaped thing at the end of your pipe cutter.

Stabby spear shaped thing Wouldn`t be the deburrer by any chance (Probably been another long hot day for you).

Can I ask a dumb newbie question, why is that? as in, all the videos I've seen always mention the tape?

Mate there are so many "Bad" video`s out there made by amateurs for their 15minutes of fame.

I've got one of those go round and round and round cutter disc thinggies, need stabby thing - check lol

Ah ok, the next fitting I won't bother with the tape, what manufacturer do you pros use for fittings? Eventually, I'm going to head to soldering.. but have way too much to do as it is

I saw this whilst searching on google for crushed compression joints, can't wait to hear your reactions!

Don't think the squeak point are the threads BTW, it's when the olive is biting against the fluted mating point on the nut. I use that as the bite point where the two surfaces are matching shape, providing the seal.

That's a different application, it's not a compression fit with an olive to seal. That is using the tape on the threads to provide the water/gas tight seal, the same as in an outside tap into a wall plate fitting would use PTFE tape in the same way.

I did a load of compression fittings 10 years ago with no issues, did some las year and it was a nightmare!.

I had some old 15mm pipe offcuts and the pipe was notably thicker (wall thicness) than the new pipe. I also think copper olives are better but not readily available bundled with the compression fittings.

I resorted to fit and crimp, then unscrew the fitting and wrap the olive in PTFE and final fit and tighten. Pipe was brand new, cleaned and deburred.

Considering going over to solder joints if I have to do any more plumbing, could use the Rothenberg torch for unseizing bolts as well so a good investment!.

I`m thinking that photo is staged, I`ve worked with oil and water fittings and can`t recall one where the pipe goes right through the fitting on a T.

If the pipes are dry to start. You really want to solder them.

If you have one or two that leak out of say 20 then that's just sod's law.

If you're getting 15 out of 20 leaking then the problem lies at the other end of the spanners!

Is soldering relativity easy to do? I've done circuit boards in the past, but realise they bear no resemblance to a bit of copper

I've been looking at the normal irons, or the torches, I'm assuming a mini torch will be the best option as tight corners and the temperature etc?

Ha! I'm 99% sure it's at the spanner end!

Buy Yorkshire fittings, a gas torch either one that connects to a camping bottle or has its own, some flux, some wire wool and basically keep the fire off the joint, but on the pipe so that it only cooks off when the fitting is hot enough. I personally add an extra dollop of solder when its melted out.

wire wool the jointing ends and inside of the fitting.
spread flux on the contact points.
