H-type clamp sleeve used for securing hoses on ends without a locking mechanism connecting the sleeve to the end. It can also be used on NiTO ends and quick-connect ends. Low-pressure hoses up to approximately 30 bar (depending on diameter) made from various materials can be used with clamp sleeves, provided that the hose material is sufficiently soft for this type of clamp. Primarily rubber hoses with textile reinforcement and PVC hoses. There is also the possibility of crimping hoses with a steel braid (e.g., PZ type hose). The internal diameter of the sleeve should be selected according to the external diameter of the hose, while ensuring that the diameter of the hole at the front of the sleeve matches the used end. Diameter D2 [mm] – internal diameter. Diameter D3 [mm] – hole diameter. Material: carbon steel, galvanized.
