I received my kit from fittings2u early last week, it was the crimped one, I gave them a call and explained that I had purchased from them because their kit was the only one that was a screw fitting, (as pictured in their listing) and that I didn't want a crimped one as they are know to leak, the lady I spoke to said she would organise a screw fitting kit for me, 2 days later it turned up, with a preadressed post bag so I could send the crimp one back to her. great, friendly service.
