It would appear that these are upside down! I had to turn the other way around to make it fit my 15mm x 22mm - why don't they have 15mm x 22mm - it's 2 packs they could have added one 15mm x 22mm and the other 22mm x 15mm.
Male on 22. Female on 15.
Not much else to say
2 in the bag
And i have a spare now.
Works as intended and solders well. Clean and good fit
Great bit of kit and working well. No issues at all
