<h2>Overview</h2>
<p>The Victaulic 2-1/2″ pipe coupling gasket is a high-quality elastomer seal engineered for mechanical grooved pipe connections. With a 73mm outer diameter, this gasket is molded to fit precisely within Victaulic coupling housings, ensuring a secure, leak-tight joint across hydraulic, pneumatic, water, and plumbing systems. <strong>Victaulic coupling gaskets</strong> form the critical sealing element in mechanical pipe joints, combining resilience with pressure-responsive performance to maintain integrity under normal pressure, vacuum, and dynamic conditions.</p>
<h2>Key Features</h2>
<ul>
<li><strong>Pressure-Responsive Sealing:</strong> <cite index=”3-1″>The gasket is pressure responsive, providing increased sealing action as the internal pressure is increased</cite></li>
<li><strong>Triple-Seal Design:</strong> <cite index=”3-6″>Creates a permanent, leak-tight triple seal on a variety of piping materials including steel, stainless steel, aluminum, pvc, ductile iron and copper</cite></li>
<li><strong>Precision Molding:</strong> <cite index=”1-1″>Each elastomer gasket is molded to fit the cavity of the pipe coupling housing, and when energized during tightening, is responsible for creating a positive seal on the pipe</cite></li>
<li><strong>Elastomer Formulation:</strong> <cite index=”1-3″>Victaulic has developed elastomer material properties through 100 years of field experience and in-house material formulation, engineering design and quality control</cite></li>
<li><strong>Compact Design:</strong> 73mm OD for 2-1/2″ grooved pipe connections with minimal footprint and low assembly time</li>
