657

DESCRIPTION

Type 657 is designed for static sealing of SAE standard flanges where it is successfully used due to its compact size. The advantages compared to O-ring sealing are mainly in:

- Thanks to the optimal geometry, the "pumping" effect during rapid pressure changes and      pulsations can be avoided
-  Increased contact sealing area
- Excellent resistance to extrusion
- significant reduction of the risk of possible leaks

For extreme operating conditions from -56 °C to +110 °C, the dimensions listed below can be supplied in other material versions for larger series.

MEDIA

The polyurethane seals are suitable for mineral oils, HFA, HFB pressure fluids. The temperature limitation for HFA and HFB fluids is up to +60 °C, for HFC fluids up to +40 °C.
Operating conditions   

    
Temperature range: -30 °C / +100 °C (mineral oil)
