V-PACK ROD 160X130X28 POM/NBR-FABRIC

STE121-160-130-028 is a v-pack rod that works as single acting - 3 pieces and can be used in piston applications. The material used on this v-pack rod is made of NBR. The maximum allowed pressure is 400 BAR.

The dimensions has an inner diameter of 130 mm, an outer diameter of 160 mm and a height of 28 mm.

About the sealing profile STE121

STE121 Packings are made up of several ‘’V’’ shaped rings in combinations that are preformed and moulded with NBR applied on NBR-fabric. They consist of 3 elements in total. The first element is a POM front ring, then 1 fabriced NBR middle ring and lastly 1 fabriced NBR-ring. These packings are recommended to be used in piston applications and assembled to open seal housing.

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.
