Which statement is true about shelf life?

• A. An O-ring has a shelf life of 5 years
• B. A V-ring has a shelf life of 20 years
• C. A Viton O-ring has a shelf life of 3 years
• D. An O-ring has a shelf life of 10 years

Answer: (A)

Shelf life is how long a stored seal can be kept before its performance may be compromised, based on material and storage conditions. For elastomer O-rings used in ALREMP, the standard stored shelf life commonly cited is five years when kept in original packaging under proper conditions (protected from heat, ozone, sunlight, and moisture). That’s why the statement about a five-year shelf life for an O-ring is the best choice. The other options assign longer or shorter durations to specific ring types or materials (like V-rings or Viton O-rings) that aren’t aligned with the typical stored shelf-life guidance, so they don’t fit as accurately.
