Installation Procedure

1. Ensure the mating groove is clean, free of debris, and properly lubricated with a compatible lubricant. 2. Carefully stretch the O-ring over the smaller component or into the groove, avoiding excessive stretching or twisting. 3. Gently seat the O-ring within the groove, ensuring it is not pinched or damaged by sharp edges.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Overstretching the O-ring during installation.Gently stretch the O-ring just enough to fit over the component or into the groove. Avoid pulling to its maximum elasticity.
Installing the O-ring without proper lubrication.Apply a thin layer of O-ring compatible lubricant to the O-ring and the groove to facilitate installation and prevent damage.
Using the wrong O-ring material for the fluid medium.Verify the chemical compatibility of Buna-N with the specific fluids, solvents, and temperatures encountered in the application. Consult material compatibility charts if unsure.
