Good afternoon all, does anyone know if you can get a 3/8 x 10mm John guest compatible straight or elbow adaptor? I’ve had a 3/8 tube between the insinkerator filter and a 10mm supply which has been intermittently reliable for a couple of years however it now is slipping out of the 10mm elbow. The tube came with the tap assembly and I can confirm 10mm tube is too big for the filter head. Other suggestions welcomed!
