STA151-015-022-004N1 is a u-ring that works as single acting and can be used in rod applications. The material used on this u-ring is made of NBR 90 shore. The maximum allowed pressure is 160 BAR.

The dimensions has an inner diameter of 15.87 mm, an outer diameter of 22.22 mm and a height of 4.76 mm.

About the sealing profile STA151

STA151 Rod seals are designed only for rod applications. Their inner sealing lip is shorter than the outer lip.

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.
