Inquiry (采购产品): Breathing hose Hello! We are currently looking for suitable breathing hoses for a rebreather project we are working on, and after some initial research it looks like you have the knowledge that is necessary to provide us with a good solution. So, what kind of hoses do you think will be appropriate for such an application? Is it correct that the DARPRO cover is the green outer reinforcement that can be seen on the breathing hoses on the Halcyon RB80 rebreather? It seems to be very rigid to me. Also, we have been thinking about using Polyurethane bellows as counterlungs, or do you think other materials will be better suited for underwater use? We appreciate all tips and knowledge that can be given in order to improve the initial layout and design!
