Reasons and Countermeasures for O-ring Leakage

As a commonly used seal, the Encapsulated O-rings may leak under certain circumstances.

The following are some analyses of this problem and Sunpass's countermeasures:

1. Quality issues:

Sunpass Encapsulated O-rings are made of Japanese Dakin raw materials, which are excellent in ductility and elasticity, and the light transmittance of FEP materials is extremely high.

The products undergo five strict quality inspections before shipment, and use precise process flow to ensure the accuracy of the dimensions, and are committed to providing customers with high-quality O-rings.

2. The matching degree between the workpiece and the seal: Ensuring the matching degree between the seal and the workpiece is one of the key factors to prevent leakage.
3. The precision of the workpiece: Insufficient precision of the workpiece and rough surface may cause the O-ring to be damaged during installation, thereby causing leakage.
4. Irregular installation operation: Irregular operation during installation is also an important cause of leakage.

In response to the above problems, Sunpass has developed a set of detailed installation and operation guidelines in combination with domestic and foreign industry standards and professional advice from industry experts, aiming to reduce the leakage rate of the Encapsulated O-rings in actual working conditions.
