Which item has the longest shelf life among the three?

• A. O-ring
• B. V-ring
• C. Viton O-ring
• D. Gasket

Answer: (C)

Shelf life for seals hinges on how the material resists aging from heat, ozone, and chemicals. Viton is a fluorocarbon elastomer known for outstanding temperature stability and chemical resistance, so seals made from it tend to keep their elasticity and sealing capability much longer than seals made from more aging-prone materials like standard nitrile, neoprene, or silicone. That longevity is why a Viton O-ring is the best pick among the options for lasting performance in storage and use. The other options can vary a lot because their base materials aren’t as resistant to aging under typical storage conditions. A generic O-ring, a V-ring, or a gasket can all be made from materials that degrade faster or suffer compression set over time, making their shelf life shorter on average. So, the Viton O-ring stands out as the most durable choice for a longer shelf life.
