Common Reasons for Metal-O-Ring Failure

While O-Rings are an incredibly useful sealing application, they are not infallible. When they fail, it’s usually because of the combined adverse effects of several environmental factors.



The most common causes of O-Ring failures include:

• Improper gland design, allowing for too much or too little compression, not enough for seal expansion and tolerance stack-up.
• Incorrect O-Ring size.
• Incompatibility of O-Ring elastomer and environmental elements.
• Improper O-Ring installation.
• Inadequate O-Ring lubrication.

The blend of weights on the Metal-O-Ring can be intricate and hard to assess. In this way, it is urgent that both the O-Ring compound and size be tried in the genuine environment of its administration. Underneath you'll discover three case of the sorts of O-Ring disappointment that can happen, what causes the disappointment and how to distinguish and redress it.

Designing an Metal-O-Ring involves rigorous testing and attention to detail. In order to meet high-quality standards — like in the aerospace and medical industry – we cannot leave room for error.

The lesson:

The combination of stresses that act on Metal-O-rings can be complex and difficult to evaluate. Because of this, it’s important to be aware of common O-Ring design flaws to help prevent failures within your system. And remember, with flaws or without flaws, it’s equally important that both the O-Ring compound and size be thoroughly tested throughout the process.
