MAV QD size?

[PEDiver]

I have a SG Defender and need to replace the QDs on the dil/oxygen MAVs and it is not a standard 3/8 fitting. Does anyone know the correct size? I’m having trouble finding anything online. Thanks all.

9/16?

How about a pic. I have a sub gravity mav and it takes 9/16 and 3/8 fittings.

I haven't seen one that didn't use a standard regulator hose. Either the 1/8 female opening or a male 9/16.

I believe it is 9/16. Here is a photo.

That's a 9/16 fitting. Sometimes they use a bushing to get it down to the standard 3/8.

They're usually lock-tited in so make sure none of that crispy lock-tite is dropping into the cartridge.

Sub gravity sells them you might have to call, or you can get a bushing to reduce that to a 3/8 unf

Be gentle with metal to delrin connections. Do not use loctite, do not try to tighten it too much either.

Thanks guys. I emailed SG to see if they have replacement 9/16 QDs since I didn’t see them listed on their website. For that matter, I’m having trouble finding them anywhere.

To your point @kensuf I’ve been very gentle with removing and reinstalling them. I’ve stripped delrin before on accident and learned that lesson. Gently snug and don’t over-tighten.
