The CS21-P is a precision-engineered symmetric single-acting rod seal, uniquely designed with an O-ring in the groove to provide consistent preload. Its sharp-edged sealing lips make it exceptionally effective for high-viscosity media, ensuring a superior sealing effect across all pressure ranges up to 400 bar. When paired with specialized materials, it excels in extreme cold environments down to -50°C. This seal is highly recommended for holding or positioning functions due to its zero-reverse-leakage design and high back-pumping ability, offering a reliable, machined alternative for demanding hydraulic operations.
