HP hoses

[GF99/99]

I have an old transfill whip that needs a new hose. The DIN tank fittings I have are 1/4" NPT and then I have NPT to JIC adapters screwing into them. So all I need is a 1-1.5m long 1/4" JIC hydraulic hose but... How clean is an "industrial" off the shelf hydraulic hose???

What are others using for high pressure hoses?

What are others using for high pressure hose.

Not this type of hose that's for sure.
But it's easy to ascertain suitability.

1. Look up the registered trademark for Titan Hose (Its registration number is 5582182)
2. Read the information given under the heading 017.
3. Titan Hydraulic hose classified under 017 together with garden hose watering hose from the wonderfully named jundun-electrical-appliance-co-ltd et al is your first clue where we are going.
4. Then read the specification for said Titan hose as quoted.

Rubber, gutta-percha, gum, asbestos, mica and goods made from these materials and not included in other classes; plastics in extruded form for use in manufacture; packing, stopping and insulating materials; flexible pipes, not of metal. - Rubber, gutta-percha, gum, asbestos, mica and goods made from these materials and not included in other classes; plastics in extruded form for use in manufacture; packing, stopping and insulating materials; flexible pipes, not of metal.

Then ask yourself why no one in the diving business is selling this crap
but at least you can make an informed choice if you are still happy on using this junk. Knowledge is power.
But it's fine when down on the farm fixing your tractor I guess. Iain

Two items listed above that should be interesting for a diving breathing applications are Mica and Asbestos
For mica there is mica pneumoconiosis a neglected occupational lung disease

And asbestos a harmless little lung irritant but when these small particles build up in the lungs and develop into mesothelioma that in the USA in 2016 past exposure led to nearly 40,000 deaths

Short-Term Asbestos Exposure | How Much Is Harmful?

Short-term asbestos exposure is categorized as lasting less than a few days. Learn whether there are risks involved with one-time exposure to asbestos.

Both listed a components in your proposed cheap transfer hose. Makes you wonder. Iain

Fresly made (off the shelf) hydraulic hoses are clean. We use it to transfill oxygen/nitrox/air.
If you are suspicious about it - hose can be easily cleaned using brake cleaner spray.

hose can be easily cleaned using brake cleaner spray

And can still be used with breathing air/gas without issues to the diver?

That is why I am asking the exact question "what are others using for high pressure hoses?" Also the screen shot was just the first thing that came up on amazon when I searched 1/4" female JIC hose. It was just for reference.

So what is a suitable JIC fitting hose then?? working pressure 200bar.

Yeah I agree that sounds a little scary. Brake cleaner is nasty stuff.

 

[GF99/99]

Ok I think I have the answer to my own question. I asked around to a friend that has a friend that use to setup alot of compressors and he said they just use Parker 520N hydraulic hoses as well for most of there applications where they need flexible line, and SS hardline where possible.

Anyone have any input on Parker 520N hose?

Of course they are not. Sometimes you use lubricant for easier handling, this is not clean at all. The hose itself may be dirty, you never know it's history. The mechanic does not wash his hands befor making the hose.

For god's sake to not use break cleaner. This "cleans" breaks, they don't have to be perfectly clean. Break cleaner always leaves residues.

If you want to clean hose's inside use hot water and a lot of soap. Press it through the hose by water pressure. Then clean it by a lot of hot water. Threads can be cleand by soap and toothbrush.
