<h3>Application</h3>
<ul>
<li><strong>Pharmaceutical:</strong> Automated filling lines and blister packing machines.</li>
<li><strong>Food & Beverage:</strong> High-speed rotary cappers and pasteurization tunnels.</li>
<li><strong>Chemical:</strong> Drum filling stations and hazardous material storage systems.</li>
</ul>
<h3>Precautions</h3>
<ul>
<li><strong>Temperature:</strong> Operate within -20°C to 80°C to prevent deformation.</li>
<li><strong>Pressure:</strong> Ensure torque does not exceed 5 N·m to avoid thread stripping.</li>
<li><strong>Maintenance:</strong> Inspect liners daily for integrity and replace worn sealing gaskets.</li>
