VR 3 Cable Leaking?

Peter Piemonte · 12th July 2006, 12:27

While soaking my KISS in fresh water after a weekend of diving, I noticed some very small bubbles emitting from the cable end. My O2 was on and the loop full of gas, and venting from the overpressure valve. The cable was leaking from around the pins. About 1 small bubble ever 3-4 seconds.
I sent an e-mail to Delta P asking if this was a problem, but have not heard back from them. Others have told me it is not a problem. I am concerned however that over time salt water will ingress the cable and cause problems.
Does anyone else have this issue or know if this is normal or not?
Thanks for any info you have. Regards, Peter Piemonte

Normally the Fischer connector are only sealing to the outside of the cable, this is where the . Most cables have a hollow inside (not moulded), however when the connector is mounted on the cable, this hollow part is squeezed thight. The Fischer connector is NOT built to have water getting to the pins, but seals around the connector housing to the bulkhead connector in the VR3 (O-ring in the VR3 connector).

If you have an sealed connector in your scrubber, I would be concerned, because this should be hermetic, not letting air or water in or out.

So my suggestion:
1. Never get water onto the pins
2. If you do you may spray lightly with WD-40 or similar.
3. Use a cap/plug on the connector when rinsing the equipment.

See the Fischer catalog for more info on the connectors

Petter

Does the unit hold neg / pos pressure checks?

Peter Piemonte · 12th July 2006, 14:14

Yes, the unit holds both pos and neg pressure.

***Beanie*** · 12th July 2006, 14:20

does it still do it with a VR3 or and end cap on it?

Peter,

My preference for protecting contacts and cleaning them is ProGold. You can get it at Radio Shack.

You can also contact Kevin Juergensen if you need a replacement here in the US. He has both the 2 and 7 pin versions. It's a lot cheaper and quicker to get one from PA than the UK

His contact information can be found on http://www.rebreather.us/

Beanie: No the cable does not leak when attatched to the VR3. I do not have a cable end cap. It did not come with the cable which I purchased from Jetsam. I am still awaiting a reply from Delta P. Peter

Hey Pete, great diving with you last weekend, I finally made it home yesterday afternoon and slept for 17 hours, making up for missing sleep in the snoreatoriam : )

I have heard of this from a couple other divers, it seems to be gas leaking through the inside of the sheathing around the wires. The cable they use is not internally sealed. However it also doesnt seem to be a problem as it is only transmitting gas from the ambient pressure loop and then out the end before the pins. Unless you flood the back of the sensor, salt water should not get in. Another guy who has this effect going on is a converted dolphin diver using a P port for the sensor.

Have you noticed it doing this under water?

Peter, Dont hold your breath while you wait ;-) They can be really slow to respond. I phone them if I need anything and they are good at answer the query then. Understand this may not be practical for you as you are in US.

Ron: Great diving with you as well. I noticed the cable was leaking when I was cleaning it after the Spikefish trip. I never noticed it leaking duribg the dives, and I am sure I would have (noticed it) whith little else to do during deco! The consensus seems to be that it should be OK. I'll monitor it over the next couple of dives.
I feel your pain regarding catching up on the lost sleep. Those offshore trips can be grueling! Best Regards, Peter
