Flomasta Compression Tank Connector 22mm

I have fitted one of these to my garden water butt as the plastic fitting supplied was flimsy and leaking.

Problem I have I cannot find a 'Female' Socket/Adaptor/bush etc to fit on the male 22mm tank connector, looked high and low on Google.

Still searching, but seen that the 22mm thread maybe a UNS 1 1/8” x 14 TPI thread if there are any plumbing fittings of that nature
The Flomasta fitting threaded body measures 33mm (1-1/8”) dia, although the compression nuts and olive is for 3/4” pipe.
The tank connector will have a 22mm compression fitting you will need to put a short piece of 22mm pipe into it. From there it will be easy to find whatever fitting you need. A female fitting sized to fit a 22mm compression thread will be very hard, if not impossible to find.
As a temp job and its purpose, I have ground off the head of a compression nut to make a miniature female socket.

Theres about 3 threads in each half to a male 22mm to male 3/4” bsp adaptor with sealant on the threads to seal.
