OLEAR hose fittings Germany OLEAR model OLEAR price

OLEAR hose fittings are straight-through connectors used for linear connections such as instruments. Connection methods include socket welding or threaded connection. They are mainly used for small-diameter low-pressure pipelines, for parts that require frequent assembly and disassembly, or for final adjustment of pipelines using threaded fittings. Relevant products are all listed by Kuaiyiyou. The structural form should preferably adopt a metal face contact sealing structure. Gasket sealing structures are generally used in general pipelines transporting water, oil, air, etc., and are made of malleable cast iron. In addition, application requirements and quotation are also factors to consider during selection. Straight-through hose fittings come in a variety of types. Commonly used straight-through hose fittings can generally be divided into hard hose straight-through fittings and soft hose straight-through fittings. If classified according to the connection method between the straight-through hose fitting and the pipeline, hard hose straight-through fittings include flare type, ferrule type, and welded type, while soft hose straight-through fittings are mainly crimped rubber hose straight-through fittings. The connection methods for pipelines and straight-through hose fittings in hydraulic systems also differ; the pipe insertion end uses connecting threads. Tapered threads rely on their conical body to tighten and use materials such as polytetrafluoroethylene for sealing operations, and are mainly used in medium and low-pressure hydraulic systems.

OLEAR hose fitting installation

1. Saw off seamless steel tubes to the appropriate length and remove burrs from the port ends. 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-line length from the tube end face to the bending section 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 inserted fully), 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 further by 1/2 turn. 6. Remove the pre-assembled fitting body and check the embedding condition of the ferrule cutting edge. The visible raised ring 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, mate it with the compression nut, and tighten until an increase in tightening torque is felt. Then tighten further by 1/2 turn to complete the installation.

OLEAR hose fitting maintenance

1. Cut off the leaking pipeline. This is a relatively simple method to handle water pipe leaks: cut off and reinstall. This method is actually not difficult; as long as you have not concealed the piping material inside the wall, it should be feasible and quite thorough, because the advantage of PP-R piping is precisely that its welding strength is higher than the base material, ensuring the overall tightness of the pipeline. 2. Use adhesive. This method is generally only suitable for pipelines with relatively low pressure; the operating pressure must not exceed 4 kg. This method is not very suitable for PP-R products, because the PP-R material makes it difficult for adhesives to dissolve/bond effectively. 3. Water pipes will age and become damaged after prolonged use, so leakage is normal in such cases. If inspection reveals that the drain connector is leaking, first cut off the end of the damaged water pipe, purchase a new water pipe, align and install it with the original drain connector to replace the damaged section, insert it into the original pipe configuration, apply adhesive to ensure a tight bond between the new and old pipes. 4. First, use a small hacksaw to cut off the leaking section—the cut must be flat. Gently sand the newly exposed port with sandpaper, but not excessively. Wipe the port clean with a clean cloth. Apply special adhesive to the port and let it air dry for a moment; meanwhile, apply adhesive inside the 'bamboo joint' connector. Connect the port to the 'bamboo joint', rotating repeatedly until secure.
