The RSO seal type has been developed to replace or work jointly with stepseals in PTFE, because of the same groove dimension.
Internally it has a round groove where an O-ring can be inserted and housed. The O-Ring acts as
energizer for the static and dynamic sealing lips even without pressure.
This profile has also excellent results at very low speed and pressure, because of the low friction.
The machining of the groove is easier thanks to the reduced axial dimension.
The proposed material is a “C0” type polyurethane, with high elasticity modulus, low compression-set
and high abrasion resistance.
O-ring in NBR 70 (N0).
As for all seal housings, remove any flash or cutting edges.
