TYGON hose fittings Germany TYGON model TYGON price

TYGON hose fittings connect different hydraulic components (pumps, delivery lines, directional valves, shut-off valves, hydraulic motors, hydraulic cylinders, and some auxiliary components, such as level gauges, thermometers, pressure gauges, etc.) to form a closed-loop hydraulic system. Hydraulic pipe fittings are accessories that serve a connecting role in this process. Hydraulic pipe fittings are detachable connectors between oil pipes and oil pipes, or between oil pipes and hydraulic components. They should meet requirements such as easy assembly and disassembly, reliable connection, reliable sealing, small external dimensions, high oil flow capacity, low pressure loss, and good manufacturability. Hydraulic pipe fittings are widely used in various aspects of our lives. They are mainly used in hydraulic piping systems across industries such as energy, petrochemicals, electric power, ships, automobiles, rail transit, mining, metallurgy, steel mills, offshore engineering, and construction machinery. Construction machinery is where hydraulic pipe fittings are most extensively used.

TYGON hose fitting working principle

1. The basic structure of this type of fitting is relatively simple, consisting of only three basic parts: the fitting body, the ferrule, and the nut. The main component is the ferrule, which is a metal ring with a cutting edge at the front. International standard GB3764-83 recommends a uniform I shape for the cutting edge. 2. The ferrule, which provides the primary sealing function in this fitting, moves axially along the inner tapered hole of the fitting body under the axial force of the tightening nut R. At the same time, the cutting edge end undergoes radial contraction under the radial reaction force R', eliminating the gap between the ferrule and the tube, causing the cutting edge to contact the tube surface. At this point, the tube no longer rotates. Continuing to rotate the nut causes the ferrule's cutting edge to firmly bite into the tube, ensuring a seal. Another sealing element is formed by the tight contact between the intersection line (edge) of the 13° chamfer at the ferrule's cutting edge end and the outer circle, and the annular conical surface of the fitting body, creating a sealing band. This is the main sealing area of the ferrule-type seal. The rear 86° conical surface of the ferrule undergoes radial contraction under the force of F, tightly gripping the connected tube. Simultaneously, the middle section bulges slightly, giving the ferrule axial elastic deformation, which benefits both the ferrule seal and prevents the tightening nut from loosening.

TYGON hose fitting maintenance

1. Cut off the leaking pipe section. This is a relatively simple method for handling water pipe leaks: cut off the section and reinstall it. This method is not difficult; as long as the pipe is not concealed within walls, it can be implemented and is quite thorough, because the advantage of PP-R pipes is that their 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; 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 over time, making leaks normal. If inspection reveals a leak at the drain joint, first cut off the end of the damaged pipe. Purchase a new pipe, align it with the existing drain joint, install it, replace the original damaged pipe section, insert it into the original pipe, apply adhesive, and 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 do not remove too much material. Wipe the port clean with a clean cloth. Apply special-purpose adhesive to the port and let it air dry for a moment; meanwhile, apply adhesive inside the 'bamboo joint' fitting. Connect the port and the 'bamboo joint', rotating repeatedly until secure.

TYGON hose fitting usage

Different hoses require hose fittings for connection. There are various types of hose fittings, and the connection method generally involves crimping with a hose crimping machine. The specific procedure is to select the hose, cut it to size, strip the hose cover, install the hose fitting, crimp it with the hose crimping machine, trim any rubber burrs, 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, we introduce how to ensure sealing when connecting hose fittings and hoses. Let's take a look. One. What is a hose fitting? When using different types of hoses, a specially made fitting is required for normal operation. A hose fitting is the component that connects hoses. There are generally multiple types, including flare-type ferrule fittings with 24°, spherical joint fittings or same-angle conical surface joint fittings, ferrule-type tube connection fittings, conical angle connection fittings with 60°, hollow hose screw connection fittings, and threaded connection fittings with or without sealing grooves.
