Guarnizioni in poliuretano tipo FNI
The gaskets in polyurethane type FNI are indicated for the sealing on rod with double lips. The assembly of gaskets type FNI for rods is not particularly difficult because the material is elastic and highly tear resistant, which eliminates the risk of damage to the sealing lips during assembly. It is useful, though not necessary, to lubricate the seat and the using the same fluid as in the system and chemically compatible lubricant
Type FNI polyurethane gaskets must be used in working condifions within the following limits.
Pressure 0 to 500 bar (50 MPa or N/mm2)
temperature -40 to +105 °C
Speed up to 0,8 m/sec (50 mlmin)
Fluids, mineral hydraulic oils, mineral lubricants.
Dimensions according to standard ISO 5597
Please contact our engineering department if you have particular operating conditions.
