The SMS relates to Swedish Metric Standard hygienic fitting. It is developed for applications that do not demand constant disassembly of hoses. It contains an internally threaded ring, which has a captive seal intended to ensure sleek, rupture-free inner hollow.
The tightness of this installation system is guaranteed by the captive seal placed into the groove on the part which is pressed by mating part. Manual tightening is adequate to maintain a liquid-tight seal. However, wrench tightening is advisable and recommended to guarantee further contact between components.
It is probably the most common hygienic fitting used globally.
