Buffer seals are primary seals in tandem sealing configurations. Designed to withstand pressure peaks from the system, Parker hydraulic buffer seals employ an unsymmetrical cross-section design and are often combined with anti-extrusion rings to prevent gap extrusion. State-of-the-art designs include a pressure-relief functionality from the low pressure side, addressing concerns related to drag-oil pressure trapped between the tandem elements. Our comprehensive selection of premium buffer seals are designed for use with hydraulic cylinders, providing excellent wear resistance, and high pressure capabilities. Parker buffer seals combine advanced polymer materials, such as PTFE or TPU with sophisticated product design.
