Flange gaskets and accessories - key elements of the installation

Flange gaskets and accessories are fundamental components of piping systems.   They ensure tight connections and protect against leaks. At Onninen we offer a wide selection of these products. Our portfolio includes flange gaskets of various types. Models are available for steel flanges for oil and gas installations. We also have reinforced versions with increased strength.

Rubber gaskets for steel flanges are very popular. They are suitable for many industrial applications. We also offer special gaskets for gas meters. Their sizes range from 38 to 70 mm. Our range also includes hydrophore sets. They are complemented by concrete settling tanks and PE nozzles.

Selection of gaskets and accessories for flanges - what to pay attention to

When selecting seals, installation parameters are key. The medium, pressure and operating temperature must be taken into account.   The seal material must be resistant to the transported substance.   For water and neutral liquids, rubber seals will work well. For aggressive chemicals, PTFE versions will be better.

The size of the gasket must fit the flange perfectly. Too small will not provide a tight seal. Too large may be damaged. It is worth paying attention to the pressure class. It should correspond to the installation parameters. In the case of high temperatures, special heat-resistant materials are necessary.

  • Check the media in the installation
  • Determine operating pressure and temperature
  • Measure the diameter of the collar carefully
  • Choose the right gasket material
  • Make sure about the pressure class

In our daily practice, we see how important the right choice is. An inappropriate seal can lead to failure. The consequences of such failures can be expensive. That is why we always advise caution when choosing. Our specialists will be happy to help you choose the optimal solutions.

Flange gaskets and accessories - Onninen offer

At Onninen we focus on proven brands and high quality products.   We offer seals from renowned manufacturers. Our assortment also includes our own brands. These include Onnline, Fxa and Ironside. These products combine affordable prices with guaranteed quality.

Our DN 15-100 EKO flange joint seals are an economical solution. They work well in standard water installations. For demanding applications, we recommend the DN 15-100 rubber versions. They provide excellent tightness even in difficult conditions.

Recently, we advised on the selection of seals for a large industrial plant. The client needed seals for a sulfuric acid installation. We suggested special PTFE models. They proved to be excellent in this demanding environment.

In the case of office reorganization, standard seals are most often needed. Rubber ones are great for water and sewage installations. For heating systems, we recommend versions resistant to higher temperatures. Our experience allows us to select optimal solutions.

  • Standard flange gaskets
  • Versions for aggressive media
  • High temperature resistant models
  • Gas meter seals
  • Mounting accessories for flanges

We often come across the question of the durability of seals. It depends on many factors. The key factors are the working conditions and the quality of assembly.   A properly selected and installed gasket can last for years.   However, it is worth checking their condition regularly. This will help avoid unexpected failures.

Many customers ask us about customization options. At Onninen, we offer custom-cutting seals. This allows us to meet even the most unusual requirements. Our machinery allows us to precisely execute orders. We also guarantee short lead times.

Our experience shows that it is worth investing in quality. Cheap substitutes often turn out to be expensive to operate. Failures and downtime generate significant costs. That is why Onninen recommends proven solutions from renowned brands. They ensure failure-free operation of the installation for a long time.

In the case of large industrial projects, the comprehensiveness of the offer is crucial. Onninen provides not only seals, but also a full range of accessories. We offer screws, nuts and washers for flange connections. Assembly tools and sealants are also available. This means that the customer receives everything from a single source.

Flange gaskets and accessories are seemingly small items of crucial importance.   Their proper selection ensures safety and efficiency of the installation. At Onninen we provide professional advice at every stage. We invite you to contact our specialists. We will help you choose the optimal solutions for your needs.
