Needed these to join rubber hose.Fitted in conjunction with worm drive clips also purchased from Tool Station. did a perfect job.
This one works lovely, don’t get the end feed version, it’s too small on the 1/2” side
Good quality yorkshire fittings, always helpful to have in your kit of parts
If like me you need to make mods to old Imperial copper piping, you will need these to transition to 15mm pipe. There really is a need for these, and they really do work.
