Shortening a LP inflator hose

[tursiops]

It is not worth the risk. A LP hose failure will drain a full tank in less than 2 minutes...so a failure toward the end of the dive means risking not enough air to get to the surface, even if you start up immediately. It doesn't matter that the probability of failure is low; the consequeneces of failure are so high that the risk is not worth taking.

If you actually tried the Omni Swivel fitting on your hose, you would be less concerned. When I compare the barbs and crimps on many imported hoses with the OmniSwivel repair, the hand-screwed fitting is actually more secure.

But @Tracy has a point. While relative Intermediate Pressure remains the same as you descend to great depth, absolute Intermediate pressure inside the hose rises significantly. Thus, your hoses become quite stiff and at risk for fracture at the flex point of the barb. Omni-Swivel or regular, don't yank on your hoses at great depth. If the Omni-Swivel barb is significantly larger than your particular hose ID, you might create a stress point. In that case, I'd agree that it's a risk. But otherwise, I have several Atomic Comfort Swivel houses that I've modified to be "perfect" necklace length with that fitting.

Hi!
I see this thread continues.
Totally out of my lane, but I had a thought.
Where I live in East Tennessee USA, we have a lot of farming and construction.
Most auto parts stores can fab up a hydraulic hose to length, onsite, immediately if they aren't busy. In addition to hard line, I have purchased flexible hose with fittings there.

I don't know what I don't know, and I am hazy on if you could O2 clean such a thing, but seems kind of like if you bought the fitting online and took the hose assembly to them, they could potentially do a factory-quality modification for you, at relatively little price.

I'm surprised you don't want to shorten the brake hoses on your car. Ridiculous and dangerous is all I can say at the moment.

I usually lengthen mine when adding bigger discs and or calipers or increasing suspension travel

I've done exactly this with Atomic Comfort Swivel hoses. They're great! Just too long.

Am I missing something? Doesn't this cost more than a new hose?

I can see having it in a SAD kit.. maybe? In my experience the crimps either leak when new or they don't.

Does anyone know if a new hose is leaking and you recrimp would it seal? I have like 5 or 6 brand new hoses that leaked right out of the box. Not sure what yo do with them but I hate throwing away good stuff.

A hydraulics shop can crimp them properly for you, the factory is not using some voodoo ritual to magically seal it.

I agree, but can they be re-crimped if leaking?

A company that builds hydraulic hoses, can eaisly do it for what a new inflator hose would cost, so why bother. We have several in the Tampa area and I used one to make a car tire inflator hose that attaches to my first stage. I just took an inflator hose and had them add about 10' of hose in the middle of it. I use it for cars and my motorcycle and neighbors.
