Bucchi srl for pipe fittings adopts as standard connection ISO 228/1; in order to
improve hydraulic seal has decided to create its own internal regulations, based on a soft conical thread. Therefore it is noted that to ensure the hydraulic seal declared it is expected a slight tightening with a key that does not generate the breakage of the coupling.
