Mini SGB clamp with a diameter of 17-19 mm. Made of steel, galvanized to be protected against corrosion. The robust structure is ensured by a tape with a thickness of 0.6 mm and a width of 9 mm, screwed using #7 spanner. It is excellent for gripping rubber and silicone hoses (including soft vacuum hoses). Gently rounded edges prevent cutting the hoses.
