Do not use a tube cutter. In the case of thin-walled or soft pipes a reinforcing ring must be used. Thoroughly oil the socket threads and cone, inner union nuts and cutting ring. For stainless steel cutting ring fittings PASTE ES must be used (optional for NC screw con- nections). Push the union nut and cutting ring onto the tube. Ensure the correct position of the cutting ring/NC compression ring - otherwise the assembly will be incorrect. Loosen the union nut as far as possible by hand. Attach the marking of the union nut for checking the specified rotations. Press the tube to stop in the cone - otherwise no cutting process can be carried out. Tighten the union nut by approx. 1 rotation (DIN cutting ring fit- tings), or. approx. 11/4 rotations (NC compression ring fittings) using the screw wrench. The tube must not be rotated. Loosen the union nut to check the assembly. Cutting ring: The raised tube material must cover the front cutting ring area. If not, re- tighten slightly. Due to the spring effect of the cutting ring, this can still be rotated - no functional error. NC compression ring: The compression ring can no longer be displaced. Endmontage: Assemble the union nuts on sockets until there is a noticeable increase in force. Then, tigthen with 1 / 2 rotation (DIN cutting ring fittings), or 1 / 4 rotation (NC compres- sion ring fitting).

PASTE ES would be most suited for this application. PASTE ES is a white paste on the basis of synthetic lubricant. It contains high pressure and high temperature resistant ce- ramic components through which even under extreme operating conditions, metal parts under pressure (e.g. threads) can easily be separated again. Advantages: Ÿ Prevents corrosion and seizing Ÿ Resistant to acids, alkalis, chemicals, fresh-and seawater, at temperatures from -20°C to +1400°C Ÿ Seals threads, flanges and housings Ÿ Saves costs by loosening joined parts (even after years), less time expenditure and less breakage Tip: For food industry applications, we recommend Loctite product 8014 (see page 559 ) Type Packing PASTE ES 500 g brush tin PASTE ES PP 200 ml press pack with elbow dispenser and brush ü Warning: Not to be used for oxygen! 200 ml press pack 500g container Perfect dosing, even at the most difficult to reach places! Advantages: Ÿ Compatible with all cutting ring fittings according to ISO 8434-1 (DIN 2353). Ÿ Also resistant to dynamic loads such as vibrations and pulsations. Ÿ It can be loosened and screwed back in as often as is necessary. Ÿ In contrast to a cutting ring the NC compression ring is not hardened, therefore it cannot rust. Ÿ Lubrication of the nut thread for initial assembly is not necessary, but recommended. Ÿ Incorrect assembly is ruled out in the face of a cutting ring or clamp wedge ring screw connection, as only one compression ring is used, which can be fitted in one direction only. An overmounting of the screw connection is not possible. Ÿ The correct assembly can be checked at any time. Processing: The screw connections must be processed with heat treated, seamless stainless steel tubes (AISI 316Ti) ac- cording to DIN EN ISO 1127. The tolerance category should be D4/T3, the surface must not show any damage and its hardness should not be more than Rockwel HRB 90.
