  | Waterproof quick disconnect couplings that work while pressureised? Does anyone know where I can get a QD for an MP hose that seals both ends and can be connected and disconnected under water without water getting in either end? Thanks in advance.

| Re: Waterproof quick disconnect couplings that work while pressureised? I don't think you will find a system with zero water inclusion. Check out THIS thread for a link Dave Sutton gave for some very low water inclusion QDs. Neil

| Re: Waterproof quick disconnect couplings that work while pressureised? I've been using Swagelok fittings. The QC6 series insturmentation fittings. I've been fooling around with my unit and different bailout scenarios so they have been coupled and uncoupled numerous times while pressuirised under water and so far no problems. They have a PDF catalog on their website of couplings. I found it by selecting any quick connect and then scrolling down where you'll find a list of catalogs you can download. The hose I ordered from OmniSwivel through my local dive shop. They may very well have something that suits your needs. |

| Re: Waterproof quick disconnect couplings that work while pressureised? IMHO .....Swagelok are by far one of the best QD . If you look them up on line you'll see that you can purchase male and female connections as DESO (Double Ended Shut off). Like the previous post ...NO MATTER what QD you buy they all will allow a very very small amount of intrusion if you connect and disconnect the fittings under water. "DESO" Swagelok fittings have the best protection in this area. The down side is they are a little more expensive. If your using them for a regulator make sure their at lest a QC6 Good luck Last edited by Frankie Pellegrino : 22nd March 2008 at 19:14. |
