S 90 STATIC SEAL
In order to meet with the needs of static sealing of larger diameters the S 90 profile has been developed.
The S 90 is interchangeable with an O-Ring of 6, 7 or 10 mm cord size.
Due to its compact nature and sealing lip geometry,
the S 90 can be applied even at high pressures, where it can compensate for cylinder tube expansion. In most cases, the geometry of the seal allows omission of backrings that would otherwise be necessary with conventional O-Rings.
