| Re: Cooperhoses on Meg I still stand by the fact that they are smooth bore polyurethane duct hose, pretty standard for use in industrial applications, with a nylon cover and the end of the spiral spring picked out at each end. The connector is a larger copy of the ones used on every bot of AP valves stuff with the split collar with the thread on the outside, albeit machined from stainless. I've looked at the Boris twice for this now and I still come to the same conclusion. |

| Re: Cooperhoses on Meg Not having seen them in the flesh, how can they be a constant smooth diameter on the inside, and corrugated on the outside? They must be made up of several layers, the inner of which is VERY flexible? Cheers, Jason. Subsea Systems - Rebreather Solutions Last edited by koputai : 11th September 2006 at 13:48.

Then you have the spiral which is embedded in the outer.CHeers, Jason.

OK, so as neither of those products looks remotely like the hoses we're talking about, are you saying that the inner of the Cooper/RE Darling hoses is just like the 63mm ID stuff from RS, and the green fabricky bit we can see on the outside is a separate cover? Are they then bonded together with the appropriate end cuff of black rubber?These are used all over industry for smooth bore delivery hose for its abrasion resistance and flexibility.

I've got some PU hose here and it's just like the Boris stuff, it really is. |

Are they then bonded together with the appropriate end cuff of black rubber? Look at the inner hose if it has a steel earthing or grounding wire running up it. This is the give away that it is a standard industrial PU process hose. Cost is around £10/mtr.Jason. The single ground wire is to earth high flow dry powders from generating static build up in industrial process. So unless you intend the diver to breathe like a train and electrolyze the amalgam in his teeth I kind of question the necessity for the steel single wire strand if the hose was "specifically" designed for diving. Woz is quite correct on the OroB version for the inner hose. Now to “process” the hose for “diving” the rubber cuff ends and the bonded outer braid are added on by the hose processor. Woz the RS example of your over braid is incorrect as these are sleeves not bonded cover. This “process” of cuff and braid bonding is the cost adder on these hoses bonding to a PU former in a uniform manner without delaminating is expensive. For those technically minded the "process" and the term "Pimp my ride" are the same. iain Last edited by iain-hsm : 11th September 2006 at 15:55. |

I have emailed them and called them and called and called and everytime they tell me they will get back to me...If we can get togeather and order a buch of hoses they might be more interested on helping us out? /Rodge I wrote them yesterday, I think they are in germany and I am in Denmark, I could try too call.
