Can't help with suppliers Rick, but the hose MUST be vacuum hose, usually identified by a yellow stripe.
Sorry if I am teaching you to such eggs, but I have seen the wrong types of hose "sucked flat" by the vacuum. Not funny on a braking system.

Are you sure you want 3/4 ID? there's plenty of regular 1/2'' on ebay and WHY.
3/4'' ID.... are you coupling up the carriages to the Flying Scotsman

Her, hum.... point of order Rick, it wasn't me that told you not to use heater hose as I'm not in the business of teaching grannies to suck eggs
3/4'' ID vacuum hose is really beyond what I would suspect you'll find on any vehicle today. I'll have a look in my Manflex catalogue later for you as I suspect it's more likely to be found in an industrial application.

Try Pirtek, they do hoses for coaches, trucks etc, etc |

The only other solution I can think of, somewhat cheaper, is to use some regular hydraulic hose, with a steel braided reinforcement it'll not even notice vacuum. As has been suggested Pirtek will maybe cut you a length (or any hydraulic supplier)
I looked in the TCC (truck and trailer components) catalogue & the UC (universal components - same as TCC) catalogue and there was no vacuum hose @ 3/4ID. So I doubt that 3/4'' vacuum hose features in trucks and buses.

I have had amazing service from the local Pertek. They seem to relish a challenge, i have gone in with two completely different sized pipes that can't be altered,but need to join together, and they have machined adaptors to fit. They have sorted me out with some very obscure fittings, off a 1960's industrial loco air system, an ancient aircraft fuel tank and a tail lift off an old truck. A bit of pipe for a servo shouldn't be a problem. Is there a branch near you Rick? |

That may not be such a silly idea as a last resort..
On a couple of occasions I have done just that to successfuly prevent a hose kinking on a difficult run with bends when no custom hose was available. However, they were not vacuum situations.

I reckon that should work, remember the spring wouldn't have to work as a spring - a length of sufficiently heavy wire wound round a suitable former would do. Make sure the coils are close enough together and it should be sorted. Cheap, too! |

Can we ask why you need 6' of this hose? Would it be possible to use 5'11" of steel/brass/copper pipe & two small connecting pieces of hose?
Alternatively, try a railway restoration site (Severn Valley?), since rly. equipment often has a vacuum braking system. _________________ Mike - MVPeters at comcast.net
