Why Your High Pressure Seal Fails? DMHUI Expert Troubleshooting Guide

Common Causes of Seal Failure:

• Excessive Pressure: Using a seal designed for lower pressure in high-pressure environments (30MPa and above) can lead to failure. Solution: Choose DMHUI's Viton TCV seal, designed to handle high-pressure systems and ensure leak-proof performance even in extreme conditions.

• Incorrect Material Choice: Using nitrile in applications with high chemical exposure can cause swelling and seal failure. Solution: Use DMHUI's Viton TCV seals for better chemical resistance, ideal for systems exposed to harsh chemicals.

• Poor Surface Finishing: An inadequately polished or damaged shaft surface can damage the seal during installation, causing it to fail prematurely. Solution: Polish the shaft surface to reduce roughness (Ra ≤ 0.8μm) and use a guide sleeve to ensure proper seal alignment during installation.
