Installation Procedure

1. Ensure the mating groove is clean, dry, and free of debris or sharp edges. 2. Carefully lubricate the O-ring with a compatible lubricant if recommended for the application to prevent tearing during installation. 3. Gently compress and slide the O-ring into the groove, ensuring it sits evenly without twisting or stretching beyond its elastic limit.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using excessive force during installation, leading to O-ring damage.Apply controlled pressure and use lubrication if necessary. If resistance is significant, re-evaluate the groove dimensions and O-ring fit.
Installing a dry O-ring in a tight groove, causing tearing or permanent deformation.Always use a compatible lubricant recommended for the O-ring material and application to facilitate installation and protect the seal.
Allowing the O-ring to twist or roll during installation, compromising the seal.Ensure the O-ring is seated squarely in the groove. A slight back-and-forth rolling motion can help seat it properly if it attempts to twist.

Common Applications
