These seals combine excellent sealability, low compression set, and superior anti-extrusion characteristics compared to other lip seals. Under low-pressure conditions, the sealing provides its own compressive seal force. As the pressure increases, hydrostatic pressure is mechanically transmitted through the elastomer seal element into the anti-extrusion base. The applied force then deflects radially in a controlled manner, closing the extrusion gap behind the sealing lip.\r\n\r\nDZ seals are also effective in compensating for high shock loads, such as bucket impacts. DZ seals have various configurations designed to accommodate standard grooves and dimensions within normal manufacturing tolerances.\r\n\r\nThese seals fit into standard deep-loaded U-cup glands. For groove dimensions, please refer to the loaded U-cups literature or loaded U-cups page<\/a>.\r\n\r\nSee DZ seals literature for more information.[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column][web3_vc_db_profiles sm=”” md=”” lg=””][\/web3_vc_db_profiles][\/vc_column][\/vc_row][vc_row disable_element=”yes” sm=”40″ md=”60″ lg=”60″ lgb=”100″][vc_column][vc_tta_tour shape=”square” spacing=”” active_section=”1″ no_fill_content_area=”true” title=”Technical Information”][vc_tta_section title=”Materials Temperature Range” tab_id=”Materials-Temperature-Range”][vc_single_image image=”568″ img_size=”full” alignment=”center” css=”” el_class=”py-40 px-15″][\/vc_tta_section][vc_tta_section title=”O-Ring Cross Section” tab_id=”O-Ring-Cross-Section”][\/vc_tta_section][vc_tta_section title=”O-Ring Gland Types” tab_id=”O-Ring-Gland-Types”][\/vc_tta_section][vc_tta_section title=”I.D Stretch\/O.D.
