ELBOW BODY ASSEMBLY1. End of fitting body (connects to tube).2. Fitting body.3. Locknut.4. Backup washer.5. O-ring seal.6. End of fitting that goes into other part.1. Put locknut (3), backup washer (4) and O-ring seal (5) as far back on fitting body (2) as possible. Hold these components in this position. Turn the fitting into the part it is used on, until backup washer (4) just makes contact with the face of the part it is used on.2. To put the fitting assembly in its correct position turn the fitting body (2) out (counterclockwise) a maximum of 359°. Tighten locknut (3) to the torque shown in the chart. If the fitting is a connector (straight fitting) the hex on the body takes the place of the locknut. To install this type fitting tighten the hex against the face of the part it goes into.TORQUES FOR FLARED AND O-RING FITTINGS
The torque shown in the chart that follows are to be used on the nut part of 37° Flared, 45° Flared and Inverted Flared fittings (when used with steel tubing), O-ring plugs, O-ring fittings and swivel nuts when used in applications to 3000 psi (20700 kPa). TORQUES FOR OTHER FITTINGS
Ermeto Tube FittingsPut nut and sleeve over the tube with head or shoulder end of sleeve next to nut. Push tube into counterbore of fitting body as far as possible. Turn nut clockwise until sleeve holds tube and prevents movement. Tighten the nut 11/4 turns more to seat sleeve and give a locking action. When necessary to assemble again, put sleeve over tube and tighten nut until a sudden increase in torque is felt. Then tighten 1/6 to 1/3 turn more to seat the sleeve. Flex FittingsPut nut and sleeve over tubing and push tube into counterbore of fitting body as far as possible. Tighten the nut until it is against the hex part of the fitting body. Hi Duty (sheer sleeve) Tube Fittings After tube has been put through the nut and makes contact against the tube shoulder in the fitting body, turn the nut with a wrench until a small decrease in torque is felt. This is an indication that the sleeve has been broken off of the nut. Hold the tube to prevent turning and tighten the nut 1 and 1/2 turns. Hi Seal Fittings Put the nut and sleeve over the tubing with the short heavy end of the sleeve facing the end of the tubing. Put the tube end against the counterbore in the body of the fitting and tighten until nut is over the last thread on the body. The remainder of space is used whenever the fitting is removed and installed again.
