STAINLESS STEEL AISI 316 W5, hose clamp, acid-resistant, has been properly studied for the most severe marine working conditions. The coupling of the band with screw has been thought that possible defections of the circular clamp, during tightening, are minimized. The screw can be tightened with either a screwdriver or a wrench, both using hand and automatic tools. The hose clamp complies with all European and American standards.
