www.stauff.com/2/en/#303 303 S Assembly Instructions for STAUFF Connect 24° Tube Fittings with Double Edge Cutting Ring (Type FI-DS) Machine-Assisted Pre-Assembly with a STAUFF Press Assembly Machine and Assembly with the Fitting Body 10mm 90±0,5° A maximum angular deviation / tolerance of ±0,5° relative to the tube axis is permissible. 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, Machine-Assisted Assembly and Inspection 3. Final-Assembly with the Fitting Body Carefully insert the assembled tube end into the 24° taper of the fitting body. Use a suitable spanner to tighten the union nut until the noticeable increase in force, and then finish the assembly with another approx.imately 1/4 a turn (90°) beyond this point. Always use a second spanner to hold the fitting body during the entire assembly procedure. In case of unfavourable mounting conditions or larger tube dimensions, use a bench vice for the assembly. A marking line applied on the union nut and the fitting body makes it easier to indicate the sufficient tightening angle. 4. Repeated Assembly With regards to assembly preparation, the actual assembly as well as the inspection of assembled tube ends, please follow the detailed instructions in the operating manual of the machine. Catalogue 2 § Edition 03/2024 Assembly Instructions For repeated assemblies, please use a suitable spanner to tighten the union nut until the noticeable increase in force, and then finish the assembly with another approx.imately 1/12 a turn (30°) beyond this point.
