Help finding MFL to 1/2" hose barb fitting

[Metric Tun]

Hello: long-time lurker, first-time poster. I'm hunting for an obscure part and was wondering whether anyone can help. I've just installed a 1.5" TC clamp into the lid of my SS Bew Bucket so I can do pressure transfers to kegs. It also occurs to me that I can purge a keg with natural CO2 from fermentation if I run a hose from the 1/2" blow-off barb (this) to the liquid-in post on an empty keg (with a blow off line from the gas post into a jar of star-san). (I do know that I could in theory daisy-chain two kegs and purge a keg full of star-san, but I can't fit my bucket and two kegs into my brew fridge so I'd rather just trust that a full fermentation will empty a single air-filled keg of oxygen - see here).

Anyway, this means I need to attach a 1/2" hose to a liquid-in disconnect. The barbs on standard disconnects are 1/4" so won't work. So what I need is THIS.

But that is the only shop I can find that sells that part, and they don't ship to the UK. Does anyone know where else I might find such a part? Or have an ingenious hack for linking from a 1/2" barb to a liquid-in disconnect?

Any advice very gratefully received - thanks!

One of these might work.

Why not use a gas in post with a 1/4" thread on it and then use a 1/4" to 1/2" reducer and fit that to a 1/2" hose barb?

Not quite as straight-forward as that.

The bit @Metric Tun is really missing is MFL 1/4 is same thread as 7/16 - 20 UNF .

Many thanks Buffers, there are some good cheap and less cheap options here.
