Shortening a LP inflator hose

[rsingler]

Give us a hint, happy.
You have a hydraulic crimper, too?

 

[happy-diver]

Nah Mr Rob they're manufactured from a manufacturer I can't have everything that I want but I'll work on it

I'm just watching a humongous container ship driving past, but I can only see the containers and the bridge

Need a better camera and scope first

What would the logical reason be to do Do It Yourself?

Because I make hoses and have access to crimper and stuff.
Because I am cheaper than a dutchman. Why throw away a perfectly good hose.. not a tree hugger by any means, but the amount of good stuff that they throw away is incredible.

Custom length or teed in order to reduce snag hazards / points of failure or for R&D to see if something works better than the present cutting edge or because some just like to tinker?

Correct...

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.

but if they leak are they really "good stuff"?

Depends.. if they didn't leak they would be good? If you could get them to stop leaking they would be good again? I think the supplier had a few issues. They sent me new hoses without question.

Maybe the hoses were scored inserting the fitting, I would give the crimps a resqueeze

There's only workshop compressor pressure going through those scuba things anyway

For land duty I've used hose, ear clamps, even oetiker clamps, covered with heat shrink

or not for my tyre pumperumperer with the also bc inflator hose adaptor

There's nothing to crimping low pressure, clampers are cheap you just have to find the thingos

But what's far more betterer is the strip of rubber I bolted between the tailgate and the bed to keep out the dust

I've used those to replace steam cleaner lines to great success. I like them better than worm drive clamps. Heat shrink with the additional glue inside/marine grade is good stuff on light duty air lines as well.

I got a hydraulic crimper. Make rubber lines hundreds of times stronger than scuba stuff, all the time. It ain't rocket science. Can't your shops custom cut hose and crimp, while you wait?

The only hard part is selecting the right crimp end for the hose. But in scuba, that's all standardized. No worries.

I used a barb just to test hose length. This industry is ignorant of different sized or shaped divers. Once I found a length I liked, I bought a new hose.

I think an Omniswivel on my necklace reg, would have helped. One if these days I'll try one.

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.

Shouldn't the hose stiffness depend also on the surrounding pressure and thus remain the same flexibility as above water?

What length do you consider "perfect" for a shortened comfort swivel hose? I know everyone's routing is different, but I wouldn't mind a starting point.

Also, can a swivel repair kit be re-used? Such as, cut hose to X length, add repair kit, decide to cut off another inch, re-use the same repair kit etc etc.
