Its technical function is twofold: to contain the high-pressure hydraulic fluid inside the power steering box and to prevent the intrusion of external contaminants (dust, mud, moisture). A loss of seal at this point results in an immediate drop in hydraulic pressure, stiffening the steering and severely compromising the driver&#039;s responsiveness to obstacles or during emergency maneuvers.<\/p>\n<p data-path-to-node=\"8\">In line with sustainable marketing and technical transparency, this steering box seal is designed to withstand the most intense friction and pressure stresses. Ensuring a perfect, long-term seal prevents premature wear of the rack or the entire steering box. Extending the lifespan of these heavy mechanical components avoids their premature replacement, thus reducing the energy and raw material consumption associated with manufacturing new parts.<\/p>\n<h3 data-path-to-node=\"10\">Technical specifications and eco-designed architecture<\/h3>\n<ul data-path-to-node=\"11\">\n<li>\n<p data-path-to-node=\"11,0,0\"><b data-path-to-node=\"11,0,0\" data-index-in-node=\"0\">Advanced fluorinated elastomer (FKM):<\/b> Formulated to withstand aggressive hydraulic fluids at high temperatures (up to +150\u00b0C) and modern power steering additives.<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"11,1,0\"><b data-path-to-node=\"11,1,0\" data-index-in-node=\"0\">High-pressure design:<\/b> Main sealing lip reinforced by a rigid metal insert, capable of withstanding hydraulic pressure peaks during full-lock steering.<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"11,2,0\"><b data-path-to-node=\"11,2,0\" data-index-in-node=\"0\">Double protective lip:<\/b> A secondary dust-proof lip effectively blocks abrasive road particles before they reach the main friction area.<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"11,3,0\"><b data-path-to-node=\"11,3,0\" data-index-in-node=\"0\">Optimized friction:<\/b> Surface treatment reducing the coefficient of friction on the steering shaft, minimizing shaft wear and optimizing the energy efficiency of the steering pump.<\/p>\n<\/li>\n<\/ul>\n<h3 data-path-to-node=\"13\">Key benefits for your safety and your fleet<\/h3>\n<h3 data-path-to-node=\"13\"><b data-path-to-node=\"14,0,0\" data-index-in-node=\"0\">Technical safety and driving precision:<\/b> By maintaining constant hydraulic pressure, this seal ensures smooth, predictable, and precise power steering.
