Installation of cutting ring fitting
Saw off the appropriate length of seamless steel tube and remove burs at the port. The end face of the pipe should be perpendicular to the axist with an Angle tolerance of less than 0.5°. If the pipe needs to be bent, the length of the straight line from the end of the pipe to the bending part shall not be less than three times the length of the nut.
Cover the nut and clamp on the seamless steel pipe. Pay attention to the direction of nut and clamp, do not install backwards.
Apply lubricating oil on the thread and sleeve of the pre-assembled joint body, insert the pipe into the joint body, and tighten the nut by hand.
Tighten the nut until the jacket jams the pipe. This turning point can be felt by increasing the tightening torque (pressure point).
Remove the pre-assembled joint body and check the embedding of the edge of the sleeve. The visible protrusion belt must fill the space of the end face of the sleeve. The jacket can be slightly rotated, but not axially pushed.
The final installation, the actual installation of the joint body thread coated with lubricating oil, and the compression nut with the screw can be felt until the tightening force increases. Then tighten 1/2 turn to complete installation.
