There must be raised material clearly visible in front of the cutting edge and should cover the cutting edge approx. 80%. . Use a suitable spanner. Tighten the union nut to the point where there is a first increase in force, the pressure point. The pressure point defines the point at which the cutting ring starts gripping the tube. 3. Pre-Assembly in the Assembly Stud The tube can then no longer be rotated in the fitting. Now tighten the union nut to the end of the assembly. The end of the assembly is situated approx. 1 turn (360°) beyond the pressure point.and is signalled by a significant increase in force. 4. Inspection 5. Final-Assembly with the Fitting Body 6. Repeated Assembly Check the soft-sealing element located on the 24° taper of the cutting ring for possible damage. Carefully insert the tube end into the 24° taper of the fitting body. The cutting ring comes into contact with the face side of the fitting body. Lightly lubricate the soft-sealing element located on the 24° taper of the cutting ring (e.g. using hydraulic oil HLP32). Do not use lubricating grease! Immediately proceed with assembly to avoid the adhesion of dirt. Carefully insert the assembled tube end into the 24° taper of the fitting body. Tighten the union nut to the point where there is a first increase in force. Then tighten the union nut to the end of the assembly. The cutting ring comes into contact with the face side of the fitting body after approx. 90°-120°. The end of the assembly is once again indicated by a significant increase in force. Use a suitable spanner to hold the fitting body within the tube during the entire assembly process. Use a bench vice for assembly in the event of unfavourable assembly conditions or larger tube dimensions. A marking line on the union nut and the fitting body makes it easier to note and check the correct tightening angle. Then tighten the union nut to the end of the assembly. The cutting ring comes into contact with the face side of the fitting body after approx. 90°-120°. The end of the assembly is once again indicated by a significant increase in force. Please note when use FI-WDDS-W5 with Stainless Steel Fitting Body: Thread and 45° cone of the union nut and thread of the fitting body grease with special stainless steel fitting grease or use a silver coated union nut. Under certain circumstances, it is still possible at this time to turn the cutting ring on the tube (radial direction). It can no longer be moved in the direction of the tube (axial direction). Please note when use FI-WDDS-W5 with Stainless Steel Fitting Body: Thread and 45° cone of the union nut and thread of the fitting body grease with special stainless steel fitting grease or use a silver coated union nut.
