So it's them small octopii that are PAS specific then?

[docchevron132]

yep, not that it matters, cos yer cant get 'em anymore.
For PAS or non-PAS.

[Bx Bandit]

Brill!

Shit loads of washer hose tubing snaking around the car will be the order of the day then. Marvellous!!!!

[Vanny]

washer hose is not oil resistant and is two halfs glued together. First the rubber swells with the oil, then it bursts at the seams. Its a great temporary repair, but it certainly doesn't last!

Silicon boost guage hose (3mm) works well, and i suspect leak of pipes will be fine too. But washer hose is a no no.

plastic bus air pipes with sealed push fit connectors. Last forever, and free from work! Jobbed.

[Bx Bandit]

Are they the type typically used in pneumatic situations Doc? Push fit jobbies with them coloured collars?

Thank you vanny, i always thought it was impervious. Ive got some stuff at work i know is though (been using it on my hydraulic brake bleeder on LHM cits for years, so i will be borrowing an amount of that for temp reapirs i think)

I've got a very long length of clear capillary tube from Laur's local DIY place, i propper DIY place which is a big hall and its impossible to find anything yourself, everything is in draws, and you ask the man, he smiles, walks off and comes back with what ever you like, including stopper tops for beer barrels and wood (including fancy skirting boards) by the inch. They even do individual tiles of most sorts, cut keys (regardless of age) and have modern things such as expanding foam filler.

yes, thats largely the thing there Bandit.
Although ours aint colour coded (done for sizing like) but since they are free then I'm not complaining!!

[Bx Bandit]

Shame, colours are pretty!

You need to be careful selecting types for BX return applications - something originally hydraulic does the job, something designed for an air-line does job much less well despite low pressure and because of lhm creep, from my experience of cobbling together tentacle substitutes and patches.

Certain copper gas-pipe plumbing style t-pieces/connectors with internal olives do the job surprisingly well, if you have a convenient and affordable supply.

[Bx Bandit]

But that sounds too stiff and unwobbly! Seriously FB, that's a good point, I'd not thought of that TBH. But it's all return, low pressure etc, what could possibly go wrong!

The stuff in work will be fine, and indeed is designed to live with oil in it.
Anyone thats stripped down an air component on a Lance will know that there's always oil residue in the lines, largely because it effectively self lubes itself!

It used to be (& probably still is) on distributed 100psi factory airline systems that at the outlet points there are two vessels in line. One is a water separator and the other is an oil separator so that the air pistols or paint guns don't eject either of these liquids from their orifices on the workpiece.

[docchevron132]

aye, tis still the case.
The bus has an air dryer that removes the moisture, but there is an amount of oil that makes its way around the air system, important for lubing the slide valves in the MCP, brake valve, door rams and the air dryer / purge valve.

This oil is engine oil and enters the system via the compressor.
If the pipes can stand that, and they have for years, then LHM should be a walk in the park!

[Philhod]

Quite correct Doc. In fact some of the larger machines I've worked on have an oil injection system. We used a green oil specially for air systems.

[mat_the_cat]

We used a green oil

LHM?

[Philhod]

Erm... no. It was somewhat thinner than LHM

[docchevron132]

ahh, that weird mineral shit that seeps through the pores of your skin and does funny things to your hands?
