Damage to O2 connector

Mark Wagstaff · 31st March 2006, 07:34

I have recently purchased a new O2 QC. As you can see from the photo the tip of the male connector has been chipped. This connector is manufactured by a Korean company called Hy-Lok. This connector is new and unused.

Comments:

1. This was air-mailed to Australia. It is possible that it was damaged in transit but the packaging was undamaged and I didn't find any chips in the plastic bag it was shipped in.
2. I would expect the tip of the connector to chip further.
2. I stand to be corrected but I don't think there are any filters downstream of the connector. Next stop; the solenoid...
3. A visual check of the connector prior to making it up each time would be a good idea.
4. Swage-Lok supply female blanking caps to protect the connectors - I'll be buying one.
5. I don't know if there is a quality issue with Hy-Lok - has anyone experienced similar?

Regards, Mark

Is there not a screen immidiately upstream of the solenoid? There is one on the Inspiration....

That will teach you to try and save a few bob Mark!

A little off topic but personally I don't recommend using equivalents no matter what make. I note that Leon mixes Hoke and Swagelok fittings, although compatible (along with a few other brands) I have seen problems in the past with tolerance issues, etc. I recommend obtaining exactly the same brand and model as the end you are trying to match.

Leon supplied me with a Hy-Lok male and Swage Lok female. I would have sourced Swage-Lok for both locally but I had to get a replacement counterlung and I thought I might as well order a few other bits and pieces at the same time.

Agreed. I'll be on the phone to Swage-Lok today. Do you know what the end fitting is? The choice is; Swage-Lok tube, male NPT, male iso tapered, female NPT or female ISO tapered. (brochure attached).

K2 is back in Perth, I'm in Melbourne. There are a few CCRs here; Prisms, Inspos and a mod'd Draeger so I'm managing to get a few dives in. Unit is performing flawlessly. Any diving in Jkta?
