Ruichen Sealing is a professional high pressure seal manufacturer in China, focusing on the research and development and production of high-pressure seals that are resistant to ultra-high pressure and extreme working conditions, serving the fields of mining machinery, petroleum and petrochemicals, aerospace and heavy hydraulic equipment. We have more than 40 patented technologies, passed the ISO 9001 international quality system certification, and established industry-university-research cooperation with Ocean University of China and Qingdao University of Science and Technology to overcome technical difficulties such as high-pressure seal anti-extrusion and long life.
Containing many of the latest national patent technologies, the high pressure seals independently developed by Ruichen Sealing have the characteristics of long life, low friction, and excellent sealing. The products are used for hydraulic nuts, plunger pumps, isostatic presses, homogenizers, etc. It is a leader in domestic high-pressure and ultra-high-pressure seals.
Ruichen’s shaft cement slurry seal utilizes a custom-profile engineered plastic slip ring paired with an O-ring to meet the requirements for both reciprocating and unidirectional rotary sealing. It is widely used in equipment such as oil and gas exploration and drilling machinery, concrete mixers, and slurry pumps. The optimized lip structure resists erosion and wear from solid particles, ensuring durable sealing and low frictional loss, while also facilitating easy installation, removal, and maintenance.
To completely eliminate high-pressure extrusion leakage in static flange sealing, the Ruichen RC2875 Axial Foot Type Combined Seal is the ideal choice. Featuring a composite design that pairs a modified PTFE foot-type slipper ring with an O-ring, its unique flanged structure enhances extrusion resistance, making it capable of handling ultra-high-pressure conditions. The self-energizing sealing mechanism ensures a tighter seal as pressure increases, while also offering compatibility with water-pressure applications.
For axial static flange sealing needs, the RC2872 Axial C-Type Combined Seal from Ruichen Sealing is the preferred choice. Available in Type A (internal pressure) and Type B (external pressure) configurations, it is designed for unidirectional static sealing applications at flange ends. Its double-sided retaining flange structure eliminates the risk of O-ring extrusion failure, while the inherent pressure-energized sealing mechanism ensures outstanding pressure resistance, making it ideal for water-pressure sealing requirements.
The RC2871 Axial Step Combined Seal consists of a right-angled filled-PTFE sealing ring paired with a rubber O-ring. It is widely used for axial, unidirectional static sealing in flange and end-connection applications and is available in two specifications: the RC2871-A (for internal pressure) and the RC2871-B (for external pressure). Featuring a long service life and a compact design that minimizes installation space, this seal is an ideal solution for hydraulic flange and end-connection static sealing. We invite equipment manufacturers to evaluate, compare, and place bulk orders for this product.
Ruichen Sealing’s GFI Piston Rod Guide Bush is specifically designed for hydraulic cylinder piston rods, primarily serving to support and guide the rod. It is available in various wear-resistant materials—such as Nylon (PA), Polyoxymethylene (POM), and PTFE—covering an operating temperature range of -55°C to +255°C; PTFE is recommended for operating temperatures exceeding 120°C.
Designed for demanding sealing applications involving water pressure and ultra-high pressure, Ruichen Sealing has launched the RC58/RC59 Reinforced Step Combined Seal for Rod. This product features a combination of a reinforced modified PTFE sealing ring and a GB1235-standard O-ring, specifically engineered for unidirectional sealing in reciprocating hydraulic equipment. An optimized, thickened sealing ring design addresses the challenges of sealing low-viscosity media (such as water), while the reinforced structural design significantly enhances ultra-high-pressure resistance.
