Trade names for NBR O-rings: e.g., Perbunan*, Nitril  Properties of NBR O-rings:  Our NBR O-rings are made of a synthetic rubber with excellent resistance to mineral oil-based oils and greases, hydraulic oils (H, H-L, H-LP), silicone (oils and greases), hydraulic fluids (HFA, HFB, HFC), as well as aliphatic hydrocarbons, air, and water.  For other oils and fuels, we recommend testing the resistance of the NBR O-ring. Good physical properties such as high abrasion resistance and durability, along with good temperature resistance, allow for a wide range of applications for NBR O-rings.  The resistance of NBR O-rings to aging, weathering, and ozone is rather low, but this is irrelevant for many applications as long as the material is surrounded by a medium (e.g., oil).  NBR O-rings are not resistant to hydraulic fluids (HFD), glycols (brake fluids), aromatic and chlorinated hydrocarbons, polar solvents, and fuels with a high aromatic content.  When selecting the right material for our NBR O-rings, factors such as the medium, the expected pressure acting on the O-ring, the temperature range for the O-ring’s application, the gap width, the surface quality of the installation space for the O-ring, and the type of application (static or dynamic) are all decisive.","brand":"keep-racing","offers":[{"title":"Default Title","offer_id":53429249179995,"sku":"29287","price":2.16,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1020\/4692\/5147\/files\/modul_e5dbdfc9-0f4e-4312-941c-c94708cfbba7.jpg?v=1785321844","url":"https:\/\/keep-racing.com\/en-eu\/products\/o-ring-fur-zylinderkopf-z-b-iame-leopard-x30-125-x-3-5mm-nbr-30-c-bis-100-c","provider":"keep-racing, we keep your heart racing","version":"1.0","type":"link"}
