PNEUMATIC PISTON SEAL 25X18X2.1

STE803-025-018-002N is a piston seal that works as double acting and can be used in piston applications. The material used on this piston seal is made of NBR.

The dimensions has an inner diameter of 18 mm, an outer diameter of 25 mm and a height of 2.1 mm.

About the sealing profile STE803

STE803 Pneumatic piston seals are designed to be used especially in short stroke pneumatic cylinders and produced from NBR material.

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.
