Could anyone tell me if i have a defective O-ring? and i do not have exact O-ring, But i have one little less bigger size and one little lesser size than exact O-ring. Then could anyone tell me which size i will use, whether little bigger size or little lesser size size & why?

 

Interestingly enough, o-rings are engineered. You should use the right one. Period. Remember, it was a defective o-ring that killed the Space Shuttle Challenger. What can using the wrong o-ring do in your plant?
