If Cooper hoses are so dangerous, why does the US Navy use them for their UBAs?

Kinda cute how you think the Navy cares about you, after equipment recovery you’re just a form letter away nonexistence.

I give up. Would be great if just someone responds with some actual data or thread reference behind this mysterious offgassing alleged in a Cooper hose. I am trying to inform strategic purchase decisions, not arguing with anyone else's based on alleged mysterious offgassing or liability disclamers that the manufacturer puts on a hose they sell to the military. "Not for underwater use" liability disclaimer is different than "offgases toxic chemicals known to the State of California to cause cancer."

@teksimple - what problem are you trying to resolve, and how do Cooper hoses represent the best potential solution given the alternatives?

Cooper hoses offer increased durability with a high resistance to tears and abrasion. Of course this comes at a premium price over regular rubber hose, not sure about silicone hoses since I have never bought any. I know nothing about the off gassing aspects but do know several people who opted to use Cooper hoses and have never personally seen any issues with them other than being a bit stiffer with some minor limitations in head movement.

Years ago, one of my long distance friends did have one of his Cooper hoses de-laminate and the interior layer on the inhale hose collapsed. It caused him to bailout out due to not being able to draw a breath. I have been firmly against Cooper hoses since that time, but have not heard of many others having that problem of the years.

I mean I agree with this sentiment. If strategic data acquisition is needed to choose even a questionable breathing hose in a life support system then that should make the choice easier not more difficult.

The Navy has significantly different risk mitigation than the general consumer market. In commercial diving that is readily apparent.

So you are saying that the Herbert Cooper hoses peeps purchase for CCR for various distributors like Sub Gravity are different than the hoses that us tax payers have funded the military for decades (not just Navy, lol, it is every service some very basic OSINT shows) to purchase as "hose, air breathing" ? I worked with the military for more than a decade, of course their bureacracy and safety standards are shite, but they still buy hundreds of thousands of our tax dollars worth of hoses labled "hose, air breathing" from Herbert Cooper.

Cooper is a tire manufacturer and they make other natural and synthetic rubber products as well. They are not a taxpayer funded project or program. But you seem to just be here to argue that they are the bees knees. No matter what you say, they remain labeled "not for underwater use"

Carry on, use them if you wish.

The last set of Coopers I picked up for my 155 took maybe a 70 days or so to receive after ordering. If memory serves they were about $105 usd per.

Edited to add:
Are any CCR loop hoses certified as breathing safe? Are any regulator hoses? None that I'm aware of at least.

None of my regulator or CCR hoses explicitly state "not for underwater use" on the product, packaging, or in any marketing materials.

My guess is that the testing and 'certification' process for one to say that a hose is good to go for mass market underwater life support may be prohibitive in relation to the market available. Most likely Cooper states what they do to help alleviate culpability in case you were to trace something to their hoses. Cooper has numerous NSN's for breathing hoses built to spec for various DoD entities.

@Borebrush - meaning, spec'ed for profitability for the lowest bidder. Dude, we've beaten this horse to death. Use Coopers if you want.
