do not buy from this seller. he is a fraud. he sends the goods after one week and does not answer the questions. he creates fake shipping labels. i never received the goods.
Arrived very quickly and well packed but they are not great quality and the seal is missing from one of them. I have spare seals in my tool bag but they don’t fit as they are about 1mm to big. The threaded nut is not exactly a tight fit as you can see from the photo.
