BAC401-089-098-002N is a back-up ring and can be used in hydraulic applications. The material used on this back-up ring is made of NBR.

The dimensions has an inner diameter of 89.2 mm, an outer diameter of 98.5 mm and a height of 2 mm.

About the sealing profile BAC401

BAC401 back-up rings are sealing elements that are generally used behind the o-ring in order to ensure system security and minimize extrusion gaps in many applications.

About the material NBR

Nitrile is a widely used nitrile butadiene and acrylo nitrile polymer. The NBR formulas typically contains between 30% and 50% acrylonitrile (ACN). The NBR which has a working temperature between -30°C and +105°C (peak temp. at +130°C) show extremely high resistance under different working conditions such as mineral oils (H, H-L and H-LP type lubricating oils) and grease and mineral based fire resistance oils (HFB and HFC group oils), vegetable and organic oils, and aliphatic hydrocarbons (propane, butane, petrol). NBR is not recommended for aromatic hydrocarbons (benzene, trichloroethylene, HFD type fire resistance oils), glycol and ether contained break hydraulics.
