TRANSTER OIL hose fittings German TRANSTER OIL models TRANSTER OIL prices

TRANSTER OIL hose fittings are widely used in high-pressure piping applications in industrial fields, such as ships, offshore oil, metal processing, and mining. Flared tube fittings are suitable for hydraulic, lubrication, high-pressure water flushing, and high-pressure air pipelines. Flared tube fittings have been certified by many auditing bodies; they offer high reliability, inherent cleanliness, and strong flexibility, with faster and simpler pre-processing assembly and installation. Flared connections require no welding, saving subsequent processes such as pickling and flaw detection. Flared tube fittings are a type of quick connector suitable for various pipe fittings and pipes with nominal pressures not exceeding 32MPa. According to flared connection manufacturers, they are widely used in industries such as oil refining, chemical, light industry, textile, national defense, metallurgy, aviation, automotive, pharmaceutical, machinery, shipbuilding, natural gas, and CNG refueling stations.

TRANSTER OIL hose fitting advantages

The ferrule, which serves as the primary sealing component in this type of fitting, moves axially along the internal tapered bore of the fitting body under the axial force exerted by the tightening nut R. Simultaneously, the cutting edge undergoes radial contraction due to the radial reaction force R', eliminating the gap between the ferrule and the tube so that the cutting edge contacts the tube surface. At this point, the tube no longer rotates; continuing to rotate the nut causes the ferrule's cutting edge to bite firmly into the tube, ensuring a seal. Another sealing stage involves the intersection line between the 13° chamfer at the ferrule's cutting edge tip and its outer circumference, which presses tightly against the annular conical surface of the fitting body to form a sealing band. This is the main sealing area of the ferrule-type connection. The rear 86° tapered surface of the ferrule undergoes radial contraction under the force of F, gripping the connected tube tightly while slightly arching in the middle. This provides axial elastic deformation for the ferrule, which beneficially supports the seal and prevents loosening of the tightening nut. Precision connection products such as ferrule fittings emerged after the Second Industrial Revolution and form a foundation of human scientific and industrial development. Manufacturers continuously engage in product research, design, and testing to develop various supporting products that maximize market demand satisfaction and secure a competitive advantage.

TRANSTER OIL hose fitting functions

Whether pneumatic quick-connect fittings or manual quick-connect fittings, they are both connector tools for sealed connections; the difference lies in whether they are driven by air pressure or manually. In different application projects, the roles and advantages of pneumatic quick-connect fittings vary. Stainless steel tubes have a smooth surface, high hardness, and resistance to high temperatures and pressures, and are often used as materials for precision equipment components. Qualified inspections of stainless steel tubes are required, including airtightness testing. According to feedback from test engineers, as shown in the figure above, one end of the stainless steel tube has been welded shut, and pressure needs to be applied from the other end to test the sealing of the weld. In this case, pneumatic quick-connect fittings can be used, employing an external wrap-around sealed connection to better ensure inflation speed. After connecting the corresponding air hoses to the fittings, if used for automated or semi-automated operations, the mounting holes must also be connected to the corresponding cylinder fixtures. Here, the role of the pneumatic quick-connect fitting is to provide sealed connectivity for pipe fittings, assist in testing, improve test efficiency, and enhance test stability. Its advantages include more convenient pneumatic operation, O-rings that grip the tube wall without causing scratches, and stable sealing for more accurate test results. In practical applications, one end of a plastic pipe fitting is connected to the equipment, which pressurizes internally via other methods; here, the pneumatic quick-connect fitting serves to seal the pipe opening. Plastic pipe fittings generally have low hardness, are easily damaged, and are prone to scratching. Due to batch production and inspection, pneumatic fittings are needed to integrate automated operations. Their advantages include being gentle on the test workpiece tube walls without causing scratches, suitability for various pipe fitting materials and properties (including some hoses), and ease of integration into automated operations to improve efficiency.

TRANSTER OIL hose fitting precautions

Before installation, all steel pipes can be pickled according to the requirements of Chapter 9, especially steel pipes connected to ferrule-type tube fittings, which should be pickled first, and then the ferrules should be pre-tightened onto the pipe ends; (2) All tube fittings should be cleaned with kerosene before installation, and the o-type O-rings inside should be temporarily removed and stored, to be placed back during formal installation; (3) During construction, keep the oil ports of pumps, distributors, and other equipment, as well as the openings of tube fittings and pipe ends, clean, preventing water, dust, and other foreign matter from entering; (4) Pipelines should be laid in a free state; excessive radial force must not be applied to forcibly fix and connect pipelines after welding; (5) Check the oil holes of bearing housings in advance to ensure internal oil passages are unobstructed and that the oil port threads match the fittings.
