Saw off tube in right angle and at least 10 mm from the cut made by the tube manufacturer / supplier in order to avoid failures caused during shipment. Only use proper tube sawing machinery or equipment. Do not use tube cutters or grinders as this may result in unwanted angled cuts and cause severe burring. H 2 x H R For tube bends, the length of the straight section of the tube end to the start of the bending radius has to be twice the height of the union nut. max 0,2 x 45° max 0,2 x 45° Slightly deburr inside and outside of the tube end (max 0,2 x 45°). The assembly area of the tube has to be free of contamination, chips and paint. Please note: Improperly prepared and contaminated tubes will affect the service life of the connection and may result in leakage. 1. Tube Preparation 2. Assembly Preparation Please note: Hardened final assembly studs are wear-resistant, thus allowing for consistent assembly results with a maximum degree of accuracy, reliability and process stability. However, they have to be checked for dimensional accuracy regularly. Assembly studs that are damaged and/or dimensionally not accurate must be replaced under any circumstances! Lightly lubricate the 24° taper of the final assembly stud (e.g. using mineral-oil based hydraulic fluid HLP32). Do not use lubricating grease! Immediately proceed with the assembly in order to avoid exposure to contamination. Consecutively put the union nut first and then the cutting ring onto the tube end. Pay attention to the correct alignment of the cutting ring: The cutting edges have to face to the tube end. Carefully insert the tube end into the 24° taper of the final assembly stud and push it firmly against the inner stop. The tube must be held in this position during the entire assembly process in order to avoid faulty assembly. Typical damages include widening of the 24° angle or the entire taper, as well as material erosion.
