<h2>Overview</h2>
<p><cite index="3-1">Chesterton 1400R is a unique, reinforced, braided, graphite tape packing with a corrosion inhibitor.</cite> The Chesterton 1400R 0.312" spool (part 001054) is a universal mechanical packing suited for both rotating shaft equipment and static valve stem applications. <cite index="3-3,3-4">The carbon yarn reinforcement is provided within the graphite tape yarn as well as the braided construction.</cite></p>
<h2>Key Features</h2>
<ul>
<li><cite index="3-5">Forms a homogeneous mass under gland pressure, so that leakage is minimized in the packing set</cite></li>
<li><cite index="3-6">All-carbon/graphite set withstands higher shaft speeds while limiting shaft/stem friction</cite></li>
<li><cite index="3-7">Structural carbon fiber reinforcement drastically lowers extrusion when installed in valves at higher pressures</cite></li>
<li><cite index="3-10">Self-lubricating to reduce shaft or stem scoring and extend packing life</cite></li>
<li><cite index="3-9">Dual purpose design makes it a truly universal mechanical packing</cite></li>
</ul>

</ul>
<h2>Typical Applications</h2>
<p>The Chesterton 1400R is engineered for demanding industrial service in both rotating and static applications:</p>
<ul>
<li><strong>Power Generation:</strong> Boiler feed, condensate, and hot water circulation pumps; turbine lube oil and steam valves</li>
<li><strong>Pulp & Paper:</strong> White and green liquor systems; refiners, agitators, and mixers; high and low pressure feeders</li>
<li><strong>Chemical Processing:</strong> Heavy-duty pumps and valve stem sealing across wide pH ranges</li>
<li><strong>Emissions Control:</strong> Block valve stem packing for fugitive emissions reduction</li>
</ul>
