Use grease on the O rings every time you separate the Q/D's. Saves the O rings getting "nicked" on rejoining and gives the Q/D's an easier time and the male part is less likely to break.

Whoa there...!! Who’s this impersonating someone who knows a thing or two about Gs’s?
Good to see you back, sir
Any general purpose grease or silicon type? Probably should have thought about using grease long ago.

I always use silicone grease as it's fine for both natural and synthetic o-rings.

Had a look in my box of scuba diving spares and the LP port plug of a regulator seem to have the 99% the same o-ring. no 10 or 11 o-ring according to the charts. The one on the right is from the LP port plug and on the left is the o-ring from Motoworks. Seems the o-rings used by diving equipment is a lot cheaper than those supplied by motorcycle shops.

I was JUST about to go into the garage to replace the plastic QDs on my 1150 with metal ones bought unused off here. I did note that neither of them had o-rings and took photos to post a query on here to see if they should be fitted.
When pushed together, they do seem very firm but I assume from your comment, o-rings a prerequisite?

The required O ring is missing from the pictured connector
Here's Motorworks item, with O ring https://www.motorworks.co.uk/vlive/Shop/Parts.php?T=6&Q=FUA59119A&search=SEARCH

I got them from Bahnstormer's.
I changed both pairs.
The plastic ones looked fine but over time go so brittle .
Hi Steve
Where did you buy that from. Looks like coupling for compressor hoses to me, looks very strong.

Having revisited the photo they are not same as standard BMW/Motorworks item (thanks meintjiesj )
Are they suitable as petrol line connectors - don't know
Do they need an O ring - would have thought so but don't know for sure
If they do, will the BMW/Motorworks O ring fit?
Suggest you question your supplier for confirmation
I bought them off a GSer on here, being sold as replacements for the plastic ones. It's looking like I naively believed them to be direct replacements for the plastic ones 
I also ordered 4 O-rings from Motorworks last night so we'll see if they fit next week.

.......unless they work 
sure my hornig metal connectors having got o rings..
Well, received my O-rings from Motorworks and would you believe it...they don't fit my metal connectors (Surprise. Surprise.)
Looking at the recess where one would think the O-rings would fit, I note that it marries-up inside the 'female' part where there are 4 very small ball-bearings (along side a 'male-like' pin). I believe these fit into the recess to allow it to snap it into place. Quite securely I may add.
There is writing on the side of the female part of the connectors..."Parker* Rectus*21*M in Germany"
I've attached a couple of photos as examples of the design.
I guess I'm grasping at straws in the faint hope that they will work on the GS...before I throw them in the bin!
It has been confirmed that I can't find out who sold them to me as 'for sale' items are deleted after 6 months so a big thank-you to that GSer.
Thanks to the above contributors for your patience with this 'naive' purchase.

Have you tried testing them? They may already be sealed against petrol leakage...
Those are air hose connectors, no O rings on them.
These are the ones that use O rings.

Found this for you https://www.parker.com/literature/Quick%20Coupling%20Division%20-%20Europe/Catalogue%20Pages_Websphere/CAT-3800-PNEU-GB_Series%2021%20Safety_Fittings_Catalogue_English.pdf
Suitable for liquid & gas. I'd be inclined to contact the manufacturer, & ask if suitable in a fuel line, & if O rings required.
Or, simply write these off & get the proper connectors
