LINK-SEAL hose connector Germany LINK-SEAL model LINK-SEAL price

LINK-SEAL hose connector is a type of hose connector mainly composed of three parts. Metal hose connectors are used in many places. The main component of the metal hose connector, the bendable part, is made of braided metal wire. Metal hose connectors offer good performance and come in a wide variety. Different types of metal hose connectors have different characteristics, structures, and maximum temperature ratings.

LINK-SEAL hose connector precautions

Do not use hose quick connectors for applications other than fluids. Please do not use with fluids other than the specified compatible fluids. Do not exceed the maximum operating pressure during use. Do not use outside the specified temperature range to prevent deformation of sealing materials, which can easily lead to leaks. Do not subject to artificial impact, bending, or stretching to prevent damage. Do not use in environments contaminated with metal powder, sand, or dust; using quick connectors in such conditions can ensure long service life even under harsh operating conditions. Accumulation of debris can cause poor performance or leakage. Do not disassemble the quick connector.

LINK-SEAL hose connector advantages

Ferrule-type copper tube connector—Advantages: simple structure, reliable sealing performance, easy to use, precision manufacturing, lightweight and attractive appearance. No gaskets required, no welding needed, saves material, and offers good performance for repeated assembly and disassembly. Since stainless steel ferrule tube connectors cannot be welded, this reduces the impact of pipeline impurities on system performance. Therefore, stainless steel ferrule tube connectors are increasingly widely used in hydraulic and pneumatic equipment pipelines with oil and gas as media, especially suitable for situations with fire hazards, high-altitude work, and frequent assembly/disassembly. They are currently being vigorously promoted and used in China. Ferrule-type copper tube connector—Structure and principle: The basic structure of this connector is relatively simple, consisting of only three basic parts: the connector 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.

LINK-SEAL hose connector function

Whether pneumatic quick connectors or manual quick connectors, they are both connection tools for sealed connections, differing in whether they are driven by air pressure or manually. In different application projects, the roles and advantages of pneumatic quick connectors vary. Stainless steel pipes 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 pipes are required, including airtightness testing. According to feedback from test engineers, as shown in the figure above, one end of the stainless steel pipe 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 connectors can be used with an external wrap-around sealed connection to better ensure inflation speed. After connecting the corresponding air hoses to the connector, 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 connector is to provide sealed connectivity for pipe fittings, assist in testing, improve test efficiency, and enhance test stability. Its advantage lies in more convenient pneumatic operation; the sealing ring clamps the pipe wall without causing scratches, ensuring stable sealing and more accurate test results. In practical applications, one end of the plastic pipe fitting is connected to the equipment, which pressurizes internally via other methods; here, the pneumatic quick connector serves to seal the pipe opening. Plastic pipe fittings generally have low hardness, are easily damaged, and prone to scratching. Due to batch production and inspection, pneumatic connectors are needed to integrate automated operations. Their advantage is being gentle on the test piece pipe walls without causing scratches, suitability for various pipe materials and properties (including some hoses), and ease of integration into automated operations to improve efficiency.
