Installation Procedure

1. Ensure mating grooves are clean, free of debris, and properly lubricated with a compatible lubricant. 2. Carefully stretch the O-ring over the smaller diameter of the assembly or slide it into the groove, avoiding any sharp edges or excessive stretching. 3. Ensure the O-ring is properly seated and not twisted within the groove before engaging the mating parts.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using excessive force during installation, leading to nicks or cuts in the O-ring.Employ gentle, controlled movements and use appropriate installation tools to prevent damage to the sealing surface.
Installing a dry O-ring, which can cause friction and premature wear.Always lubricate the O-ring and mating groove with a compatible lubricant to reduce friction and ensure smooth installation and operation.
Selecting an O-ring material with inadequate chemical resistance for the application fluid.Thoroughly verify the chemical compatibility of Buna-N with all fluids and environmental conditions the O-ring will encounter.

Common Applications
