hydraulic ferrules installation

  Hydraulic ferrules Installation: Saw a suitable length of seamless steel pipe, removing burrs at the port. Tube end to the vertical axis. If you need to bend the tube, from the end face of the tube to bend parts of the line segment length can not be less than three times the length of the nut. The nut and condoms on the seamless steel tubes. Note the direction of the nut and ferrules, not installed backwards. In the pre-assembled connector body Lubricate threads and put the card, insert the tube Hydraulic  ferrules  body (tube must be inserted in the end) Tighten the nuts by hand. Tighten the nuts until the card sets stuck pipe, this turning point tightening torque can be increased by feel (pressure points). After reaching pressure points, and then metric hydraulic fittings the compression nut half circle. The pre-assembled connector body removed, embedded Check card sets blade edges, protrusions visible ferrule end face must be filled with spaces. Card sets can be slightly rotated, but not axial passage. Final installation, thread coated with oil in the joint body will actually install, co-ordinated with the compression nut screwed to increase the perceived tightening force so far. Then tighten laps installed.
