RHD oil pressure line

[stickandrudderman]

Gents, I need to make an oil pressure line for a RHD car but am having difficulty a) establishing a supplier for the parts, b) establishing the method of construction (are the ends flared or soldered) c) establishing the threads on the fittiings (i don't think they're metric but haven't actually measured them yet) and d) establishing the material (i believe steel).
Anyone got any leads or nuggets of wisdon to share?
I have established that the pipe should be OD 3mm or 1/8" and approx 160cm long but that's as far as I've got.

UPDATE: The threads on the tube nuts are M8 x 1.25 and the original pipe is magnetic so presumably mild steel.
Further update: the flare is a DIN mushroom 37 degree flare. (Now I need another special tool.....)
Third update:
Having removed one from another car I can confirm that the pipe is 1100mm in length.

Which line exactly are you talking about? OD 3mm?

[stickandrudderman]

The rigid line to the oil pressure gauge Pawel.

Hi Colin,

Mine is in the car but not connected to anything as yet.

Happy to get the verniers out to take any measurements and/or pics you need.

Just not right now, already on the couch relaxing and it’s too dark and cold outside for me, cause you know I’m upside down on the world.

Can do it tomorrow, just let me know what you need?

Doug

Thank you.

Maybe the pictures here will help a bit...

That's very kind doug.
I need thread pitch for the tube nuts at each end and overall length of the pipe.
That would be great thanks.
I suspect that the summer weather we are experiencing here in London is no better than your winter weather there!

Pawel,
all the usual suppliers only supply for LHD which is shorter and AFAICT they all supply in copper which is not correct.
The SKF link is useful, thanks, but it appears they don't list 3mm OD tube.

Just a wild guess here, but can't you obtain a more common LHD oil pressure line and use the ends of that (and perhaps the fittings) as a template to create the elusive RHD model? I'd imagine the fittings are the same, the threads are the same, the construction is the same, just the length and bends are different.

[stickandrudderman]

Sure, I could cannabalise the LHD pipe for the tube nuts but it seems they're fairly easy to procure. The pipe itself has flared ends which have to be made.

[Duncan200]

Ok,

So I’ve braved the cold weather and I can confirm that it is an M8 x 1.25 fitting on either end and the fitting measures 28.39mm.

My line is fitted in the car, but it roughly measures 100cm, I think 160cm would be far too long.

It is 3mm diameter mild steel pipe.

Let me know if you need more info or pics?

Doug.

[stickandrudderman]

Thanks Doug.
Next quest is to find a supplier of 3mm or 1/8” mild (not stainless) pipe and a flaring tool that will enable me to make the pipe.
Several hours of trawling the internet have not yielded results.
Of course, it would be easy to have a plastic pipe made but it just wouldn’t look right.

i have bought pipes and fittings and flaring tool from Wide Bay Brake Hose service. Bob owns and runs it and is super helpful. in Queensland

Colin,

Have you looked at aluminium pipe from a hobby shop?

Like you I can only find stainless and it would be next to impossible to flare.

Brake pipe and the respective tools are not appropriate for this part.

Third update added…

Turns out the oil pressure line from a 110 is the same so I got lucky.......
