The SMS union is the Swedish standard hygienic fitting. It can be recognised by the round slotted nut and square section joint ring. Probably the most widely used hygienic fitting worldwide, there is always a small crevice between the face of the male spigot and the liner which makes CIP questionable. The use of L section joint rings with the standard union parts should be avoided as the male spigot can cut the lip on the joint ring causing subsequent product contamination. Where a true crevice free assembly is required, the SMS Aseptic union should be used.
