1. S1– the gap between the sealed surfaces should not exceed half of the maximum clearance corresponding to the H8/f7 fit for pressures up to 50 MPa.

2. Dimensions, manufacturing tolerances, edge radiusing, and surface roughness are based on the industry standard BN-82/5284-01.

3. It is possible to manufacture elements in special versions for continuous operation (in oil) at temperatures up to 100 °C.
