High-quality safety clamps designed for mounting typical (EN / DIN) industrial hoses on fittings with smooth or serrated hose tails and with a safety collar (fittings in accordance with EN14420-2 / DIN2817). Widely used for rubber and some plastic hoses in the chemical industry, loading/unloading applications, food industry. They provide a secure, yet demountable attachment of the fittings. The clamps should be selected based on the inner diameter of the hose (DN) and thickness of the hose wall, which is close to the nominal thickness of the hose wall given for the clamp (g), so that the outer diameter of the assembled hose is within the range specified for the clamp (from D min to D max). Installation of the clamp (IT-53) by tightening the bolts, may require the use of long pre-assembly bolts.
