Applications and benefits of using hydraulic seals

Onnline DN125 flange gasket Klingerite A gasket is an element found in many installations, which is used to ensure the tightness of the entire system. It is most often made of flexible materials, which allows for a perfect fit to the system elements between which it is located.

In practice, seals are used in various fields - in hydraulics, gas installations, automotive systems (oils). They ensure the correct operation of many systems, which is why their durability and quality of workmanship are so important. Depending on the purpose, the seal has a specific shape and size, which, when properly matched, serves as an excellent insulator. This effect can be achieved thanks to the fact that only high-quality materials are used in the production of seals.

Types of hydraulic seals

In practice, there are different types of hydraulic seals, depending on the material they are made of. One of the basic types is a rubber seal made of rubber. It is highly flexible, which ensures excellent tightness of each system. They are durable, solid and functional. Thanks to the properties of rubber, they can be used in water and sewage systems, gas systems. They do not let water or gas through, and they also work perfectly in systems operating in different temperature ranges.

One of the advantages of silicone seals is their excellent resistance to atmospheric factors and other external factors. They are perfect where high precision sealing is required.

Fiber seals are a hydraulic seal that is mainly installed in threaded connections. They are most often found in water installations at the meter or at the heat meter. Among the advantages is the ease of installation. They are resistant to pressure, moisture, under the influence of which they swell, providing protection.

Depending on the specific application and needs, there are also flange gaskets, mainly designed to provide sealing in pipelines and some devices. They are resistant, durable, and their use is a good decision wherever possible replacement would be difficult. They withstand even heavy loads, so they wear out little.

Depending on the installation method, we can also distinguish:

  • a slip-in seal, which is mainly used in the industry dealing with the production and assembly of door and window joinery;
  • clamping seal, which is also a variant of the edge seal.

It is worth being aware that, depending on specific parameters and composition, individual variants may have additional features that affect the properties of the product.

  • seal for siphon , used in all types of sanitary, water and sewage installations, etc. This variant, due to the construction of siphons, is intended for insulating screwed elements;
