George-
Do you have a source for metric steel B nuts? I need to make some flexible
brake lines for the American master cylinders that will be installed. 12
mm thread diameter. The threads are very fine.
Thank you.

Ernie,
I think your mechanic friend has it backwards, I think it's 10 years on
the shelf and 5 years on the aircraft.
I stock a full line of all Chinese hoses, and see no problem with future
supply. I have never had call for the metal ends so I have never stocked
them.

I thought you just sold the fittings so one could make their own hoses.
Unfortunately, the CJ has a few hoses that aren't that easily made, like
the ones requireing 90 fittings as an example. I think for the individual
owner, it's just easier and probably not much more expensive to just buy
the hoses if they are readily available, rather than go through the expense
of buying the tooling to be able to perform a task that the average owner
might do once every 10 years. I'm just going to replace ALL the hoses at
once, and not worry about it again for a long while, I just checked my log
books and they haven't been replaced since the plane was certified back in
2000. A mechanic friend of mine told me a rule of thumb for hoses are 5
years on the shelf and 10 years on the airplane, so I'm well overdue.

No. We usually buy some steel fittings and turn them down and weld on the Russian fitting to make an adapter. George

We went down this path, simply because we could not get adequate supplies of the original Russian flexible material without ordering kilometres of it. I had not envisaged simply modifying the metal ends of customers to enable them to insert their own hose – remember in Europe that anything like this has been done by an approved organisation.
In terms of costs, we currently charge Euro 90 per hose (about $100) – clearly this is on the basis that we expect to get a complete set for an aircraft – and so very cheap for the big oil hoses, but expensive for small fuel ones, but a great deal simpler for us to quote and invoice.
So this includes the machining and modification to the metal ends; importing Aeroquip 303 hose material from the US; making the hose; testing it; putting on a fireproof cover; giving EASA "form1" certification, which we need to be able to use them.
But we would certainly consider modifying just the individual metal ends, which would clearly be dramatically cheaper, if there were a market. I would also point out that this is only for the Russian hose ends, but quite conceivably the Chinese ends are identical.

In Europe, an item like this can only be used with an EASA "form1", which is the highest European quality statement for an aviation product, so we have had to go through all the appropriate testing processes, which includes testing at three times normal working pressures.
The procedures add quite a lot to the cost of changing the hose on the first occasion, but then subsequently it is much cheaper.

George-
Yes, I'd do that if I could. The Aeroquip hoses work fine, and they adapt
well to the un-removable fitting on the bulkhead, if I can find a steel
metric B nut.
The fitting is riveted onto the bulkhead in the Yak 55. One can't get into
there to make any changes.

Do you have a source for metric steel B nuts? I need to make some
flexible brake lines for the American master cylinders that will be
installed. 12 mm thread diameter. The threads are very fine.
Thank you.

I stock a full line of all Chinese hoses, and see no problem with future

I thought you just sold the fittings so one could make their own hoses.
Unfortunately, the CJ has a few hoses that aren't that easily made, like
the ones requireing 90 fittings as an example. I think for the individual
owner, it's just easier and probably not much more expensive to just buy
the hoses if they are readily available, rather than go through the expense
of buying the tooling to be able to perform a task that the average owner
might do once every 10 years. I'm just going to replace ALL the hoses at
once, and not worry about it again for a long while, I just checked my log
books and they haven't been replaced since the plane was certified back in
2000. A mechanic friend of mine told me a rule of thumb for hoses are 5
years on the shelf and 10 years on the airplane, so I'm well overdue.

In terms of costs, we currently charge Euro 90 per hose (about $100) – clearly this is on the basis that we expect to get a complete set for an aircraft – and so very cheap for the big oil hoses, but expensive for small fuel ones, but a great deal simpler for us to quote and invoice.
So this includes the machining and modification to the metal ends; importing Aeroquip 303 hose material from the US; making the hose; testing it; putting on a fireproof cover; giving EASA "form1" certification, which we need to be able to use them.
But we would certainly consider modifying just the individual metal ends, which would clearly be dramatically cheaper, if there were a market. I would also point out that this is only for the Russian hose ends, but quite conceivably the Chinese ends are identical.

The procedures add quite a lot to the cost of changing the hose on the first occasion, but then subsequently it is much cheaper.

The old hose is actually a hard aluminum brake line. The B nut is aluminum. So, unfortunately, I don't have a fitting to rob a part from.
Yes, if you have two steel B nuts on an old hose, I'd love to buy it. I can measure the thread pitch as well. The threads are very fine.

Perfect, much easier than making.
Can you quote those out for me?
Thanks

Ernie,
I think your mechanic friend has it backwards, I think it's 10 years on the shelf and 5 years on the aircraft.
I stock a full line of all Chinese hoses, and see no problem with future supply. I have never had call for the metal ends so I have never stocked them.
Best,
Doug

Thanks,
I thought you just sold the fittings so one could make their own hoses. Unfortunately, the CJ has a few hoses that aren't that easily made, like the ones requireing 90 fittings as an example. I think for the individual owner, it's just easier and probably not much more expensive to just buy the hoses if they are readily available, rather than go through the expense of buying the tooling to be able to perform a task that the average owner might do once every 10 years. I'm just going to replace ALL the hoses at once, and not worry about it again for a long while, I just checked my log books and they haven't been replaced since the plane was certified back in 2000. A mechanic friend of mine told me a rule of thumb for hoses are 5 years on the shelf and 10 years on the airplane, so I'm well overdue.
Thanks

We went down this path, simply because we could not get adequate supplies of the original Russian flexible material without ordering kilometres of it. I had not envisaged simply modifying the metal ends of customers to enable them to insert their own hose – remember in Europe that anything like this has been done by an approved organisation.
In terms of costs, we currently charge Euro 90 per hose (about $100) – clearly this is on the basis that we expect to get a complete set for an aircraft – and so very cheap for the big oil hoses, but expensive for small fuel ones, but a great deal simpler for us to quote and invoice.
So this includes the machining and modification to the metal ends; importing Aeroquip 303 hose material from the US; making the hose; testing it; putting on a fireproof cover; giving EASA "form1" certification, which we need to be able to use them.
But we would certainly consider modifying just the individual metal ends, which would clearly be dramatically cheaper, if there were a market. I would also point out that this is only for the Russian hose ends, but quite conceivably the Chinese ends are identical.

Richard,
This is interesting. Are these crimp fittings or reusable?
Can you site some example prices.
Ernie

Our engine partner, Aerometal in Hungary, has developed a technology to remanufacture the Russian metal ends of flexible hoses (I have no experience, but I would assume very similar, if not identical, to the Chinese ones) in order to accept Aeroquip 303 hose. We have needed to do this to overcome the problem that the original Russian hose material is simply no longer available
