LEDUC hose fittings Germany LEDUC model LEDUC price

LEDUC hose fittings are translated from the English word bushing, professionally known as reducing fittings. They are generally machined from cut and forged hexagonal bars. There are many types of threads used. They connect internal and external threaded pipe fittings with different diameters, playing an irreplaceable role in pipe connections.

After cleaning, the piping should be formally installed and greased as soon as possible. Tighten all pipe fittings section by section according to the printed mating marks. Ensure the originally removed o rings are inserted. All piping fixation must be secure and not loose. All oil supply pipes can be connected to the distributor outlet and lubrication points after greasing. Metric general threads are indicated by uppercase M. Metric general threads are divided into coarse-pitch and fine-pitch threads based on pitch. Coarse-pitch thread markings generally do not specify the pitch, e.g., M20 indicates coarse-pitch thread. Fine-pitch thread markings must specify the pitch. Threads are used for connection and fastening between mechanical parts. Coarse-pitch threads are commonly used for threaded connections. Fine-pitch threads have slightly higher strength and better self-locking performance than coarse-pitch threads of the same nominal diameter. Pipe threads sealed by threads prevent leakage without filler or sealant. Thread-sealed pipe threads include two connection forms: cylindrical internal thread with conical external thread, and conical internal thread with conical external thread. The former connection is sufficiently tight, while the latter is typically used only under high temperature and high pressure.

LEDUC hose fitting usage

Different hoses require hose fittings for connection. There are various types of hose fittings. The connection method generally involves crimping with a hose crimping machine. The specific method is to select the hose, cut it to size, strip the hose cover, install the hose fitting, crimp it with the hose crimping machine, clean up any debris, and then install the dust cap, sealing ring, and retaining ring. Connecting hose fittings to hoses is not difficult, but attention must be paid to ensuring sealing effectiveness. Below is an introduction on how to ensure sealing for hose fitting and hose connections. First, what is a hose fitting? When using different types of hoses, a special fitting is required for normal operation. A hose fitting is the component that connects the hose. There are generally multiple types, including those with 24° flare-type ferrule fittings, spherical fittings, or same-angle conical surface fittings, ferrule-type pipe connection fittings, 60° conical angle connection fittings, hollow hose screw connection fittings, and threaded connection fittings with or without sealing grooves.

1. Saw off seamless steel tubes to the appropriate length and remove burrs from the ports. The tube end face must be perpendicular to the axis, with an angular tolerance not greater than 0.5°. If the tube needs to be bent, the straight length from the tube end to the bending point must be no less than three times the nut length. 2. Slide the nut and ferrule onto the seamless steel tube. Pay attention to the direction of the nut and ferrule; do not install them backwards. 3. Apply lubricating oil to the threads of the pre-assembled fitting body and the ferrule. Insert the tube into the fitting body (the tube must be fully inserted) and hand-tighten the nut. 4. Tighten the nut until the ferrule grips the tube. This turning point can be felt by an increase in tightening torque (pressure point). 5. After reaching the pressure point, tighten the compression nut by 1/2 turns. 6. Remove the pre-assembled fitting body and check the embedding of the ferrule cutting edge. The visible raised band must fill the space at the ferrule end face. The ferrule may rotate slightly but must not move axially. 7. Final installation: Apply lubricating oil to the threads of the fitting body in the actual installation. Screw on the compression nut until an increase in tightening torque is felt. Then tighten by another 1/2 turns to complete the installation.
