UPN Rod & Piston seal
UPN type gasket, natural evolution of the UP, it is suitable for both the rod than for the piston and combines the advantages of the elasticity of nitrile rubber with the abrasion resistance of polyurethane. His profi assures him a good reaction to variable loads and reduced friction in all conditions of pressures. The energizing element inside the throat guarantees a good holding capacity too at low pressures.
