The RC2061 Reinforced Toothed Combination Seal (designed for cement slurry sealing) consists of a specially designed toothed sealing ring made of high-performance engineering plastic and a rubber O-ring; it is suitable for unidirectional sealing in hydraulic reciprocating and rotary applications. Its optimized lip thickness resists erosion from cement slurry and mud impurities, ensuring reliable sealing and low friction while requiring minimal installation space. The design facilitates easy assembly and maintenance and effectively mitigates rapid seal degradation caused by particulate matter in the medium.
It is primarily used in applications such as plunger pumps, mud pumps, screw drilling tools, drilling rigs, oil exploration equipment, and concrete mixing plants. Key features include a long service life, low friction, excellent sealing performance, a compact footprint, and ease of installation and maintenance.
When used to seal mud-like media, it is recommended to inject lubricating grease between the two (or more) sealing elements.

Note: 1. For shaft diameters ≤30 mm, an open groove design is recommended.
2. For rotary sealing applications, a shaft surface hardness of HRC ≥58 is recommended.
3. For pressures exceeding 30 MPa, an H8/f8 fit is recommended for the extrusion gap.
