General
The rod seal S2R, colloquially also called hat seal, is a simply designed seal for simple applications in the low-pressure range, which can also be used in pneumatics when special material mixtures are used. It is also available in a version with spring (MF).
Medium
Mineral oils, bio-oil, pressure fluids HFA, HFB, HFC (VDMA 24317)
Material
Standard material: NBR with a hardness of 80-90 Shore A. FKM and EPDM are also available for special applications. For high application pressure, a wear-resistant HPU may be recommended.
Advantages
- easy assembly from the outside
- wide range of materials
- quick disassembly and assembly for replacement
Installation instructions
Correct functioning of the cap seal requires careful installation. The axial compression on the flange of the seal should be approx. 10% of the flange thickness. The design should be such that the compression is metallically defined in order to avoid further force transmission and deformation of the sealing lip. In order to achieve an improvement of the fixing and sealing effect of the cap collar, it is recommended to turn one or two sealing grooves into the metallic flange surfaces. In special applications (high temperature, speed, specific pressure load or use in brake fluid, HFA, HFB fluids etc.) please contact our application engineering department.
Other
Normal application only up to 1 MPa (10 bar). With the use of a support ring, the cap seal can seal up to a pressure of about 4 MPa (40 bar).
Range of application
Low pressure hydraulics, pneumatics
