<div class="product-section-block" style="display: block; visibility: visible; clear: both;">
<h2>Product Function：</h2>
<p>The 9F-3788 Metal Seal Ring is designed for service within transmission planetary groups, torque converters, and flanged tube connections of heavy equipment. Manufactured from cast iron with a lock-type joint configuration, this seal ring acts as a dynamic hydraulic barrier to control clutch-pack oil pressure and prevent fluid cross-over. The gray iron construction provides stable thermal expansion rates and wear resistance against continuous rotational forces inside planetary gear hubs. If this metal seal ring suffers from face scoring, cracking, or joint distortion, it can cause transmission line pressure drops, slow gear response, and accelerated internal gear wear.</p>
</div>
<hr />
<div class="product-section-block" style="display: block; visibility: visible; clear: both;">
<h2>Common Failure Symptoms：</h2>
<ul>
<li>Sudden or progressive drops in transmission or planetary circuit operating pressure.</li>
<li>Harsh shifting or delayed clutch engagement during high-load heavy equipment operations.</li>
<li>Fine iron scoring debris or metal flakes captured in the main system filters.</li>
<li>Excessive heat generation inside the planetary housing caused by continuous internal fluid bypass.</li>
</ul>
</div>
<hr />
<div class="product-section-block" style="display: block; visibility: visible; clear: both;">
<h2>Installation Notes：</h2>
<ul>
<li>Clean the shaft carrier grooves and receiving bores with a non-residue solvent to remove carbon and metallic sludge.</li>
<li>Inspect the groove sidewalls and mating surfaces for deep ridges, micro-scratches, or sharp burrs.</li>
<li>Carefully expand the lock-type iron ring to pass over the shaft landing without over-stressing or fracturing the joint interface.</li>
<li>Apply clean transmission oil to the seal ring assembly to provide start-up lubrication.</li>
<li>Ensure the lock-joint ends are properly engaged and aligned before sliding the planetary housing into position.</li>
</ul>
</div>
<hr />
<div class="product-section-block" style="display: block; visibility: visible; clear: both;">
<h2>Maintenance Tips：</h2>
<ul>
<li>Maintain strict schedules for transmission fluid and filter element changes to limit abrasive particulate in the oil.</li>
<li>Regularly monitor system pressure levels to detect early signs of internal seal bypass.</li>
<li>Always install new metal seal rings whenever planetary carriers or torque converters are disassembled for major overhauls.</li>
</ul>
</div>
<hr />

<h2>Product Function：</h2>
<p>The 8S-3372 Torque Converter Seal is designed to maintain fluid retention and prevent high-pressure transmission oil from escaping the torque converter housing interface. Engineered from an advanced elastomeric compound that tolerates extreme oil temperatures and shearing forces, this seal ring fits into the converter stator or housing bore to sustain vital internal hydraulic pressure. By providing a continuous barrier, it keeps power train fluids contained while protecting the interior torque converter assembly from atmospheric debris and moisture. If this seal ring degrades or flattens, transmission oil bypass occurs, leading to low charge pressure, slipping clutches, and poor power transfer.</p>
</div>
<hr />
<div class="product-section-block" style="display: block; visibility: visible; clear: both;">
<h2>Common Failure Symptoms：</h2>
<ul>
<li>Oil leaking from the bell housing or torque converter inspection plates.</li>
<li>Drop in torque converter charge pressure, resulting in sluggish machine acceleration or power loss under load.</li>
<li>Elevated transmission oil temperatures caused by internal fluid slippage and bypass.</li>
<li>Elastomer degradation, including hardening, cracking, or loss of cross-sectional elasticity.</li>
</ul>
</div>
<hr />
<div class="product-section-block" style="display: block; visibility: visible; clear: both;">
<h2>Installation Notes：</h2>
<ul>
<li>Thoroughly inspect the converter housing groove and shaft landing surface for scratches, burrs, or wear ridges before installation.</li>
<li>Clean the assembly area completely to remove metal filings, varnish, and old oil residue.</li>
<li>Apply a uniform film of clean transmission oil or approved assembly lubricant to the new seal ring to prevent tearing or rolling during insertion.</li>
<li>Position the seal evenly within its landing track, ensuring it sits entirely flush and is not twisted.</li>
<li>Align and mate the torque converter sub-assemblies squarely to avoid pinching or shearing the sealing lip.</li>
</ul>
</div>
<hr />
<div class="product-section-block" style="display: block; visibility: visible; clear: both;">
<h2>Maintenance Tips：</h2>
<ul>
<li>Perform regular transmission fluid and filter changes to keep abrasive metal fines from scoring the elastomeric seal.</li>
<li>Monitor transmission oil temperature and pressure gauges closely during operation to identify internal bypass early.</li>
<li>Always install a new torque converter seal ring whenever the transmission or converter housing is separated for overhaul.</li>
</ul>

<h2>Product Function：</h2>
<p>The 8S-3371 Seal Ring functions as a fluid barrier within medium-to-high pressure lines, transmission linkages, and oil cooler lines of heavy construction machinery. Made from specialized elastomeric compound optimized for high chemical and heat resistance, this seal ring prevents pressurized engine oil or transmission fluid from weeping past joint flanges. It bridges the gap between mechanical mating halves, maintaining line pressures under heavy machine vibrations and cyclic operations. If the ring seal hardens or shrinks, it will compromise fluid containment, leading to continuous fluid leakage, system drop-offs, and increased structural wear on surrounding dry compartments.</p>

<div class="product-section-block" style="display: block; visibility: visible; clear: both;">
<h2>Product Function：</h2>
<p>The 8P-8950 Metal Seal Ring is engineered to maintain oil pressure and prevent fluid migration within high-temperature hydraulic paths, planetary transmission groups, and torque converter assemblies. Manufactured from gray iron, this joint-lock type sealing ring withstands continuous rotational wear and high thermal expansion without losing its structural tension. It functions as a dynamic barrier to isolate oil circuits inside heavy-duty gear systems. If the metal ring scores, snaps, or suffers severe face wear, internal pressure drops will occur, leading to clutch slippage or sluggish transmission response.</p>

<li>Fine iron scoring particles discovered in the transmission oil filter elements.</li>
</ul>
</div>
<hr />
<div class="product-section-block" style="display: block; visibility: visible; clear: both;">
<h2>Installation Notes：</h2>
<ul>
<li>Check the shaft landing surface and receiving bore for any grooving, burrs, or ridges before setup.</li>
<li>Gently expand the metal seal ring over the shaft and ensure the lock joint securely engages without over-stretching the gray iron material.</li>
<li>Submerge the ring in clean system oil prior to assembly to minimize initial contact friction.</li>
<li>Verify that the ring rotates freely within its designated carrier groove after seat installation.</li>
<li>Align mating component sub-assemblies squarely during final integration to avoid shearing the extended edge of the metal seal.</li>
</ul>
</div>
<hr />
<div class="product-section-block" style="display: block; visibility: visible; clear: both;">
