Question How to convert to QC6...

[Sevenrider860]

This is the default configuration for the Dive Rite O2ptima with BMCL. Can the LPI connector shown support full air flow to the DiveSoft BOV at recreational depths (< 130 ft)?

What parts are needed to convert this to a QC6 Female connector that would provide greater air flow?

And when do you really need a QC6 vs regular hose inflator attachment? I have read multiple times that for depth over 120ft / 40m QC6 is the way to go. However at those depths you are likely to be using less dense trimix that should offset the higher resistance of the regular inflator hose.

Because he is asking about a QC that does into a BOV open circuit regulator?

One of these on the BOV side/ Swagelok Female QC6 - Fathom Dive Systems
One of these on each of the cylinders you’re expecting to plug into your BOV:

Male QC-6 quick disconnect, 9/16"-18 male - Fathom Dive Systems

Depending on how the rest of the hoses / rig is configured, some chance of a male to male somewhere in the midst

You need a [Author edit] male female stem for the unit side, and a [Author edit] female male for your bailout.
Dive Rite and Fathom both sell the ends you need to thread directly onto your hoses.[/s]

These Omniswivel sets sold by DGX do also work (seemed fine at 90 meters)

High Flow QD Hose Assembly

This is a solution for building a low pressure regulator hose with a quick disconnect in the middle.

the omni's let too much water in so if you are planning to have to swap feeds then they aren't ideal. They're perfect for FFM's and the connection to the BOV itself but not so ideal for the dil plugins. They also aren't DESO which means the body has to be on the tank and depending on environment that can be a PITA if anything gets into the body.

A garden hose fitting would work as well, but they are also junk in this application.

Learned another term...DESO. Double-end Shutoff. Always learning...

To go on a little tangent, is it wise to be switching QDs for cylinder changes underwater? I figure the BOV is primarily there for abundant sanity breaths without needing an immediate mouthpiece switch, rather than needing to be used for an entire OC bailout ascent. BOV can be QD plugged to the 'deep' mix prior to entry/descent, and left that way. [Hypoxic gas management adds a closed valve re-opening step at minimum op depth--descent check.]

If a different, more full or more optimal gas is subsequently needed (such as a deco gas on OC bailout) then why not just a normal switch procedure to that cylinder's regulator? Is juggling QDs or playing with switchblocks going to be any safer than an ordinary gas switch?

I am aware some people / instructors / agencies like to gratuitously trade cylinders a bunch of times during courses, where yes I could see one wanting the smoothest and most DESO solution for this repetitive exercise.
