Yksi tärkeimmistä teollisista auton puhdistustarvikkeista on erityiset pesuaineet, jotka on suunniteltu poistamaan likaa, rasvaa ja muita epäpuhtauksia tehokkaasti. Nämä pesuaineet voivat olla joko biologisesti hajoavia tai synteettisiä, riippuen käyttötarkoituksesta ja ympäristönsuojelustandardeista. Esimerkiksi, ekologiset pesuaineet ovat yhä suositumpia, sillä ne tarjoavat tehokkuutta ilman haitallisia kemikaaleja. Tällaiset tuotteet ovat turvallisia sekä ihmisille että ympäristölle, mikä tekee niistä erinomaisen valinnan nykyaikaisille puhdistusratkaisuille.

Operating temperatures for engine oil seals (see Fig. 14.11 and cross-section of lip seal with garter spring in Fig. 14.22) vary widely, depending on engine design and location within the engine. Typically, the rear crankshaft seal is subjected to much higher temperatures than the front seal. Oil sump temperatures vary considerably, depending on provisions for oil cooling. This allows use of hydrogenated nitrile (HNBR), silicone, or acrylic elastomers for some seals in relatively low-temperature environments (120–140°C or 250–284°F). Standard fluoroelastomers (FKM), bisphenol-cured VDF/HFP/TFE terpolymers with 68–69% fluorine content, perform well in oil service up to about 160°C (320°F). More resistant fluoroelastomers are necessary for reliable long-term performance in more severe environments.
Oil seals are found in a wide range of applications, in virtually every industrial sector. It is essential to select the correct oil seal so that the application in which it is used can run efficiently, free of leaks or other issues. In this blog, we explain which factors you should pay attention to when selecting the best oil seal for your application.
