Acid-resistant clamp W4 BRADAS 70-90mm, BSW4 70-90/12. The Bradas worm-drive hose clamp is a rolled band clamp. Made of high-quality stainless acid-resistant steel W4 (AISI 304), which allows it to be used in aggressive working environments, at high pressures and temperatures; steel W4 also has antiferromagnetic properties, meaning a low level of magnetization. Worm clamps provide a reliable seal, distributing pressure evenly over the entire contact surface. The clamp's shape with outward-bent band edges prevents damage to the hose. Each clamp is marked with the Bradas logo and size in millimeters. Steel grade: W4. Band width: 12 mm. Clamping diameter (min): 70 mm. Clamping diameter (max): 90 mm.
