The Ruichen RC2057-B PTFE oil seal is engineered for demanding operating conditions where conventional oil seals fall short, offering chemical resistance, a wide temperature operating range, and the ability to function under low-lubrication conditions. Its low-friction design enhances energy efficiency and supports high linear speeds, while its non-stick characteristics ensure low startup resistance even after prolonged periods of inactivity.

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.
