Not sure if this is a compression fitting or what? It looks more like it might be flared in there. Sorry for the poor phone picture but it was hard to get in at.



Had the pipe replaced at a main dealer.. was expecting a factory bent line but could understand bending it as you go, it's easier, but not all that happy they haven't used one continuous length of pipe to the front. Or am I just being overly picky?

Single flare and not made at all well by the looks of the photo, although it could be deceiving.
Edited, Humph, looking at that again I wouldn't join brake pipes using that and I can't see how they've got it to seal.

They should use one female connector



and two male

It's one female and one male. One end is like you would tighten into your flexi, the other is a sort of 'nut'/'socket' for it to connect to by the looks. Does that make it a compression fitting or are there other types? I've only heard about compression and that in general you should just use one length..

The ones in your photo are flared fittings not compression, as you say the female one is what you would use to connect to a flexible pipe fitting. The male one is the same or similar to the one in my post.

Should be OK then? Still doesn't seem very impressive/professional.. *starts making brake line.. oh st this isn't long enough.. oh well I'll just join it rather than doing it properly*

There's nothing wrong with joints although I like to keep them to a minimum as it's less to fail. As an MOT tester I would fail that but that's a subjective view.

Didn't really think about that, I'm moving soon so it definitely won't be MOT'd at the same garage. Might have to go and get some more opinions.

Isn't that rather contradictory when you then say?

There is nothing wrong with brake pipes being joined per se, as there is no fail criteria in the MOT that I know of for "joined brake pipes".

On the other hand the way that the join is now resting is putting some tension on the pipe at its joined ends due to the fact that it is not completely in line with the pipe.

I would suggest that the garage has made the pipe in 2 halves for simplicity & then joined them & bent the area around the joint to its current angle, which is less than ideal.

That join is not up to main dealer standard, they could have done it properly using just one more 50p union and it would have taken no more time, ideally they would have used a single pipe.

Take your car back and ask for it to be done correctly, ie a proper joining piece as pictured above.

Is the a copper pipe joined to a copper pipe?
I wouldn't dream of doing that to a customers car when replacing the brake pipes.
Onto a steel pipe maybe, or with a female joiner like linked above but definately not the OPs pic nono

I'd be back and complaining about that if it was my car, and certainly wouldn't expect that quality of a main dealer eek

Why is this wrong? I just don't want to say can you do it correctly when I don't really know why one method is superior to the other? Thanks - just suspect I might need to fight my corner and be able to explain why I want the female connector in there.

It seems you didn't read my posts properly or perhaps I didn't make them clear. I've said that there's nothing wrong with joints in brake pipes but I like to keep them to a minimum as It's less to go wrong. I then said I would fail that, meaning the joint in the Op's original post and if you look hard enough in the MOT manual or actually sit the MOT testers course you'd see there is a reason to fail. "Subjective" as in one tester will see it as OK where another wont.
I think I should take my own advice and not get involved in other people's questions as there's always someone on PH that'll twist what another poster says.

Hope you get it sorted OP.

Pretty sure over here it would be a fail too.

From what I understand, you're not allowed to do a copper/copper joint like that, there must be steel in the middle like you pictured.

I've spoken to a number of other places today, all say it wouldn't fail an MOT, but it isn't the best choice of connector.

Would still like to know why the female one is superior though if anyone could advise smile

The way it is at present has a convex flared copper pipe end sealing against a concave flared copper pipe end.

The correct joining union is steel, meaning the more malleable copper pipe flares deform against it, providing a better seal.

Jagracer.

I 100& agree with keeping them to a minimum, ie. preferably zero. I have only ever joined 2 half pipes once in 30 odd years.

In your reply to my question you explained it with the use of the enhancement subjective, which I did not fully pick up on in your original post.

Sorry if you thought I was trying to twist your original reply around, that was not my intention, I was just trying to understand how you could say it is OK in one sentence & then fail it in another.

I'm a bit lost where we are now but just to be clear, I didn't say I have anything against joints in general, but the joint in the OP's original picture is, in my opinion, not fit for purpose.
One other thing is that if it was done at the car manufactures franchised main dealer why didn't they use an OE pipe instead of the bodge job shown?

100% agree with that, main dealer would be expected to do that for me.

I've seen two piece joints like that made as original equipment on cars so can't understand what the fuss is about.
