Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using excessive force during installation, leading to O-ring damage.Apply gentle, even pressure. If resistance is encountered, re-inspect for obstructions or incorrect O-ring size.
Installing a dry O-ring, increasing friction and potential for tearing.Always use a recommended lubricant compatible with both the O-ring material and the fluid being sealed.
Using an O-ring not rated for the operating temperature or chemical environment.Verify the O-ring material's specifications against the application's requirements for temperature, pressure, and chemical compatibility.
