hose fitting connectors installation method

Hydraulic hose fitting connectors installation method 1, under the appropriate length of seamless steel saws, 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. 2, put a condom on a nut and seamless steel pipe. Note the direction of the nut and hydraulic hose fittings , not installed backwards. 3, in the pre-assembled connector body threads and put the card Lubricate the tube into the connector body,  Tighten the nuts by hand. 4, tighten the nut until the sleeve stuck pipe, this turning point tightening torque can be increased by feel  5, after reaching the pressure points, and then hydraulic pipe fittings  the compression nut half circle. 6, the pre-assembled connector body removed, embedded Check card sets blade edges, protrusions visible space must be filled with ferrule end face. Card sets can be slightly rotated, but not axial passage. 7, the final installation, threaded greased the actual installation of the connector body, the compression nut screwed to the increase associated with the tightening force can be felt far. Then hydraulic adaptor fittings laps installed. Fittings installation instructions Inside and outside to take over the interface when installing fittings need to connect with the fittings are handled clean, take over the mouth must be polished smooth surface can not have glitches and uneven surfaces. And take over the site and fittings embedded bending phenomenon should not have, or will cause the connection fittings and steel pipe leakage phenomenon. Pipe fittings at both ends of the connection tube best uniform material, which can effectively prevent leakage. After embedding steel fittings body began efforts to tighten ferrule efforts should not be too large, should be gradual stop screwing the threaded sleeve or two-thirds of the tail, there is a wrench in the card sleeve fastening click.
